Hi,

Available information on Iaotian-1  Aotian-1 is still confusing and remains to be pieced up properly.

China has seemingly flown-tested, on september 20, 2013 an unpowered experimental vehicle code-named Iaotian-1 Aotian-1 (遨天1号 or 遨天一号in the Hulun Buir (呼伦贝尔市) region (northeastern inner Mongolia) a region of grasslands and high steppes. And now a test range too for TAEM (Terminal Area Energy Management) maneuvers / landing of a potential chinese Reusable Launch Vehicle (可重复使用运载器) contender.

This project would originate from CALT (Chinese Academy of Launch Vehicle Technology) and as such might be a direct heir of their "old" project 921-706 (the RLV rival of Shenzhou). CALT is part of CASC.

As of today, other forum sources, where chinese-speaking members comment ([Elixir] and [Henri K.] - see footnote below), indicate that:
(1) the piece of information originates from CALT;
(2) this piece of information was essentially targeted towards Western websites to pass it along, with scant information available on screened chinese forums (Weibo, etc.);
(3) one or more pictures posted on Weibo (微博) by a project member, were immediately erased, but some managed to be archived (see below);
The picture is said to originate from the following CALT-related blog [edit: latest post published by hangtianchuangxin dates back to 2014-10-30 21:18 来自 iOS, no follow up ever after]:
http://e.weibo.com/hangtianchuangxin
(4) the vehicle -- which, to the best of other knowledgable Chinese-speaking forum members, has not been pictured yet -- but would bear striking similarities with Dream Chaser (well, project 50/50 and Bor4 would have been a better historical reference for the sake of accuracy). Conditional is important: Dream Chaser was flown tested last week and there might be creating some sort of confusion here.

All of these information need confirmation from other sources.

Anyone?

PS) This post draws heavily from information made available by [Henri K.] aka [Elixir] aka [Henri Kenhmann] aka [hk299792458] (these alias equivalences were formally acknowleged on Nov.14, 2012 on defense.pk forum in response to a question by [qwerrty]) who is/are a very active blogger supposedly but very unlikely from France (法国), mostly writing in French, the language of diplomacy. The family name Kenhmann happens to be ultra-extremely rare and seems to have german origins (Kehn borrows from an old german word meaning "skiff" or "barge"). Apart from a canadian ebay account with the surname "Kenhmann", little could be found in 2012 on Henri Kenhmann, and Kehnmann in general. This(these) individual(s) is(are) active on, and inactive but subscribed to, many other space-related forums (although this might be the same person using different aliases) such as: abcbourse.com, air-defense.net,  allhtml.com, astronautique.actifforum.com, beatzone.cz, boardreader.com, boursematch.com, checkoutthelatest.com, clip.dj, daily-bourse.fr, defense.pk, dp.sina.cn, flickr.com, forumconstruire.com, forum.hardware.fr, freemp3u.com, plus.google.com, hmongplay.com, indiandefence.com, imageshack.us, livraddict.com, merops.com, militaryphotos.net, moneymakergroup.com, ps3youtube.com, shelby.tv, socialblade.com, talkgold.com, video.mivzakon.co.il, vtap.com, youreplay.com, youtube.com, etc. to name a few. It very surprising he's not an (active) member of SPF yet, since it would have been easier for us all to have him starting this new thread. I'm sure SPF members would be eager to be privileged for new scoops from this "well-known and respected forum member on Chinese military developments" (quote from [mepal1], 28/09/2013, http://www.chinesedefence.com/forums/chinese-navy/1464-type-054-type-054a-jiangkai-class-ffg-19.html/). On other forums, [Henri K] is credited with numerous records of accurate information on every possible chinese-related military fields. On 09/07/2013, sinodefenceforum.com member [SinoSoldier] wrote, without prior fact-checking: "There is this guy called Henry Kenhmann from France who works as an engineer. He has been a very close follower of the Chinese military and somehow has documents relating to weapons systems never heard of before. His predictions are scarily accurate and as far as "track record" goes, his information seems to be a lot more accurate than HuiTong. Some of his "predictions" are the 48000 ton LHD, HQ-8, HQ-26, solid state laser, etc. He asserted that the 055 will be in construction in 2013 before anyone else did, and he apparently also got these rumors: - Type 055 will have QC280 ; - Type 055 will be 12000 tons ; - It will have the Type 1130 CIWS ; - Construction will possibly begin in 2013 ; - Type 055 will have the PJ38 ; - It will have superior ECM ; - A smaller complement ; - Same radar as 052D" (source: http://www.sinodefenceforum.com/navy/type-055-ddg-plans-next-generation-destroyer-thread-3-6480.html). In light of these information, and as a key provider of goldmine chinese R&D hard-to-find information, [Henri K]'s statements on Aotian-1 should be studied seriously: [Henri K] might well be considered like a news agency (sort of), tied to -- informally or not -- chinese government-related sources/agencies/insiders (controlled "leak" and information dissemination), which make their information extremely valuable but prone to careful fact checking and always to be framed in balanced, contextual analysis. As time goes by, [Elixir] behaves like an online evangelist, with the clear intent to visibly shape one specific online environment: the perception of Chinese strength at the dawn of the 21st century, through select aerospace and military topical prisms. [Elixir] exhibits different distinct writing styles and may involve several individuals. However, given the scope and almost continuous rate of information diffusion, on an almost full-time basis on the aforementioned forums/websites, [Elixir] may also be part of a larger, plan. It may likely be considered as one of many apparent visibility modes of a well-structured, state- or para-state sponsored organization. Now, why chose the alias [Elixir] (酏) remains a mystery wrapped in a riddle: An elixir is conveniently defined as a "clear, sweet-flavored liquid used for medicinal purposes, to be taken orally and intended to cure one's ills", often presented as a "solution of at least one active ingredient" with the requirement to be "stored in a tightly closed and light resistant container away from direct heat and sunlight". [Elixir] went remarkably silent in late january 2014 on target forums of interest highlighting the difficulties for some observers to rely on this single feeding source to cast their own (actually "adroitly shaped") view of Chinese aerospace and military organizations. [Elixir] was revived and back again on the operational online information theater on 02/17/14. Their vanishing perfectly matches up with celebrations of the Chinese's New Year holidays. On April 27, 2016 at 9:12 LT [Elixir] announced pulling out from Forum de la Conquête Spatiale (FCS) claiming health reasons. A few days later, [Elixir] was back at it again, with new fluency in French and complete refurbished writing skills and grammatical style (stylometry softwares such as JGAAP could be helpful here). Could this be interpreted as a turnover? Whichever organization goes behind manpowered [Elixir] is likely to be state-sponsored. The purpose and aims of this apparent psyop yet has to be determined. But honestly, its aims are very clear. N'es-ce pas? Aller Zhu

Aotian-1 vs Shenlong

  • Needless to say, Iaotian-1 Aotian-1 should not be confused with the Shenlong Space Plane (神龙”空天飞机), developed as part of the 863 State High Technology R&D Plan (国家高技术研究发展计划).
  • The Shenlong Space Plane project was code named 863-706. As to the vehicle, it was a wingle reentry vehicle weighting 4 ton. This vehicle was seemingly flown tested several times, including at Mach 15 on January 8, 2011. Chinese media outlets used the specific expression "试飞" standing for "test flight" to qualify the test. Of additional interest, the development of the Shenlong Space Plane has been associated with the 611 Research Institute, Chengdu Aircraft Corporation, Aviation Industry Corporation of China (AVIC).

All chinese articles I read through so far (thx googletranslate!) just comment on information made available on western blogs. No real "news", actually. And lots of nationalistic statements on the glorious chinese ability to catch up with US technological marvels in force projection (with a mix of FOBS, X-37B, J-20 along the way). Few interesting comments but loads of crap. From what I could read up to now, Iaotian-1 Aotian-1 is described as a transatmospheric vehicle capable of orbiting the earth once. It is said to be similar to the "Dream Chaser". Again, this is all confusing and I am looking forward to reading other independent news to corroborate all that.

Very intriguing indeed.

Last post for today.

As of now, a search using the folliwing keyword "遨天1号" in the "image section" of Baidu (i.e. the equivalent of "google image"), direct link here:
http://image.baidu.com
... ended up with no pertinent result (unless you are a soccer lover, for whatever keyword/database reason.)

A.

PS) Edit 20160510. On may also use the following keyword: 遨天一号

Sometimes the code-name also reads/translates as "Aotian-1"

A.


[added: Iaotian-1 is one of several possible translitterations, Aotian-1 seems more appropriate]

Hi back;

First, a big thank you to Deino for having posted this thread today on SinoDefense Forum (SDF) -- I'm not a member of this forum yet -- and "asking for more". Link is: http://www.sinodefenceforum.com/

Please find below a compendium of first reactions. For the sake of clarity, capitalized words put into brackets -- i.e. [QWERTY] -- indicate a forum member alias under which the related comment was made.

Some SDF members reposted a well-known CAV-related waverider configuration circulated years ago, originating from a Chinese technical publication. Patent literature may prove to be more interesting, however.

[SINOSOLDIER], SDF member, had "heard the same thing a few weeks prior. Best to wait it out."

[KROKO], SDF member, indicated that the Hulun Buir was very close to the Russian border and expressed his "doubts that china would want to test unpowered planes on that place. Could fall into the wrong side of the border..."

[SIEGECROSSBOW], SDF supermoderator, noted that "The only information on this was the aforementioned blog post, but even that was take down pretty quickly. I think waiting is the better option here, unless you want the wall climbers to go to Inner Mongolia."

OK guys. I'll keep investigating and posting stuff until I understand what's going on.

A.

Fact checking starts with Hulun Buir region.
Yes indeed, it's upnorth and close to the Russian border.
These wikipedia maps shows us clearly where it is.

http://en.wikipedia.org/wiki/File:China_Inner_Mongolia_Hulunbuir.svg
http://en.wikipedia.org/wiki/File:China_Inner_Mongolia_location_map.svg

Challenge: identifying a test range suitable for a hypersonic winged test vehicle (in this region).

Googlemap anyone?

PLA military region where the flight-test allegedly happened.

The Hulun Buir region where Iaotian-1 Aotian-1 test flight allegedly happened is to be related to one of the People Liberation Army (PLA)'s 7 military regions (MR).
http://en.wikipedia.org/wiki/PLA_Military_Region

The only PLA MR matching the Hulun Buir geographical situation is the Shenyang Military Region (see  attached wikipedia map)
http://en.wikipedia.org/wiki/Shenyang_Military_Region
http://en.wikipedia.org/wiki/File:Shenyang_Military_Region.svg

Air Bases associated to PLA's Shenyang MR

The number of potential sites where the test flight supposedly happened is limited to 30 Air Bases of interest including the Dingxin / Shuangchengzi AB which has a special missile testing unit.

C. Kopp (Australia) has issued a page / site / report cataloguing "over 200 military and dual use airfields". "It includes Google Earth KMZ files for air bases and civil airports where the identity of the base can be established with some confidence. As all data is open source, APA cannot guarantee that the data is comprehensive or up to date in every instance. The site will be updated as more open source data and high resolution imagery becomes available."

This resource might be of interest to any one with a wish to further investigation of Iaotian-1 /Aotian-1:

source: Dr Carlo Kopp, People's Liberation Army Air Force and Naval Air Arm  Air Base Infrastructure, Technical Report APA-TR-2007-0103, 30/01/ 2007 (updates : 15/01/ 2011 ; 29/03/2012 ; 03/04/2012), http://www.ausairpower.net/APA-PLA-AFBs.html

In any case, Kopp's catalogue might be interesting to fact check any future revelation on Iaotian Aotian-1 whenever it ever gets official. If it ever gets…

To admit I would agree that Dingxin AB is the most likely base even it is much more away from Russia and located in the Lanzhou MR.

By the way there are - at least officially - not that many operational bases and in regard to Carlo Kopp I would prefer my own "sources", since the map is wrong (Map from James Lawrence published in my book "Modern Chinese Warplanes" (Harpia Publ.), p. 123)

Thx alot Deino.

BTW, at the time when the search begins for this "new" Chinese spaceplane, and I feel being not alone in this quest, counterpoints are worth reading, just to keep both feet on the ground. Years ago, the Shenlong / Divine Dragon affair broke many stories. Most of them built one upon another, iterated in closed loops and auto-citations. Whatever leak / weak signal shows up today, it is always tempting to believe in what we wished were existing while trying to connect the dots. Alas, the full-frame reality picture often happens to be less glamorous.

In that respect, the following article is worth reading:

Laura Grego (Senior Scientist), "Claims About China's Space Plane unconvincing", Union of Concerned Scientists, 07/12/2012
http://allthingsnuclear.org/claims-about-chinas-space-plane-unconvincing/

That post is by no means intended to be a showstopper - quite the opposite. It just aims at making sure we walk the right path along this snarkfullish journey currently called Iaotian-1 Aotian-1.

There do appear to be way more airbases out there than are accounted for in the PLAAF or PLANAF's ORBATs.  Carlo and I built that article and one on airfield UGFs from a massive KML I put together showing airbases in China.  If you plot the bases with "known" operational units, there are still a whole mess of airfields out there you'd be missing.  Are they all necessarily operational?  Probably not, although I did make an effort to mark bases known to be non-operational separately.

Thanks and I agree with You that there are indeed many, many more airbases out there in China, but by looking at operational ones would narrow down the hunt for this unknown base.
There problem behin that - and You mention it - is that I indeed cncentrated only on the operational ones directly assigned to a known regiment/division .... to add the non-operational ones too would have made this map even more confusing.

However - and here You surely know the material much better than me - in line of the recent developments like urban development several bases were simply given up or transferred to the civil authorities and as such "to mark bases known to be non-operational separately" would be quite usefull since many of then will never return to operational status again.

Oh, I was in no way trying to disparage your work!  The info you chose to present is perfectly logical and fits the material just fine.  My point is just that there are a ton of airfields out there that aren't necessarily going to have known operational units associated with them, and that one of them might be the culprit we're looking for here as they're far easier to overlook.

It seems the actual project name is "AOTIAN-1", not IAOTIAN-1 as initially suggested by [Henri K] on a well-known French astronautics forum. Incidentally, it happens that the initial apparent misspelling of "IOATIAN-1" enables a fairly accurate and easy tracking of how information percolates and flourishes on the web, based on a good understanding of how recent updates of google Panda + Pinguin SEO engine suites actually work.

Hi there,

Worth reading again today, a 2006 Flight magazine article by Rob Coppinger reporting that CALT unveiled its RLV roadmap at the International Astronautical Congress (IAC) in Valencia, Spain. If any september 20, 2013 flight test event ever happened, it might be somewhat described by this roadmap, even if actual details slightly differ.

The article reads: « "We don't have an official schedule for the programme, but the first generation could be developed in 15 years," says CALT research and development centre manager Yong Yang. He says CALT expects to conduct a Mach 15 re-entry demonstration flight using a winged upper stage that will be launched to an altitude of 100km (62 miles). Another planned demonstration is an automatic flight and landing test to prove guidance, navigation and control systems. No dates have been provided for these tests.»

Why would Mi-26 be involved in/for Aotian-1 flight test?
Considering the first rash of information available on weibo's blog, the september 20, 2013 flight test involved one russian-made Mi-26 heavy lift helicopter. China started to use Mi-26 in 2007 and purchased a couple of them in 2008 (see below). These helicopters have a payload capacity of 20 metric tons, and a maximum take-off weight of 56 metric tons with a ceiling of 4500 m. As such, the september 20, 2013 Aotian-1 flight test might have only been the first successful drop test, from a conservative ceiling figure of 4000m of a vehicle, for a final, unpowered glide (?), approach and landing test (ALT). The maximum weight of the test vehicle would have to be less then 20 t anyway. Nice. Hefty.
 
Mi-26 general characteristics
A Mi-26 dedicated wikipedia page details its the vehicle history, variants, characteristics
http://en.wikipedia.org/wiki/Mil_Mi-26
  • Crew: Five– 2 pilots, 1 navigator, 1 flight engineer, 1 flight technician
      Capacity:
  • 90 troops or 60 stretchers
  • 20,000 kg cargo (44,090 lb)
  • Length: 40.025 m (131 ft 3¾ in) (rotors turning)
  • Rotor diameter: 32.00 m (105 ft 0 in)
  • Height: 8.145 m (26 ft 8¾ in)
  • Disc area: 804.25 m2 (8,656.8 ft²)
  • Empty weight: 28,200 kg (62,170 lb)
  • Loaded weight: 49,600 kg (109,350 lb)
  • Max. takeoff weight: 56,000 kg (123,450 lb)
  • Powerplant: 2 × Lotarev D-136 turboshafts, 8,500 kW (11,399 shp) each
     Performance

  • Cruise speed: 255 km/h (137 kt, 158 mph)
  • Range: 1,920 km (1,036 nmi, 1,190 mi)(with auxiliary tanks)
  • Service ceiling: 4,600 m (15,100 ft)
Mi-26 variants
Below are all known variants of the Mi-26 according to wikipedia's above reference.
It would be interesting to determine which type(s) of Mi-26 was purchased by China, ands which was used during the september 20, 2013 flight test.
  • Mi-26: Military cargo/freight transport version. NATO name: 'Halo-A'.
  • Mi-26A: Upgraded version with an upgraded flight/navigation system.
  • Mi-26M: Upgraded version of the Mi-26; designed for better performance.
  • Mi-26MS: Aeromedical evacuation version.
  • Mi-26NEF-M: Anti-submarine warfare version.
  • Mi-26P: Passenger transport version, with accommodation for 63 passengers.
  • Mi-26PP: Radio relay version.
  • Mi-26PK: Flying crane helicopter.
  • Mi-26S: Disaster relief version.
  • Mi-26T: Civil cargo/freight transport version.
  • Mi-26TC: Cargo transport version.
  • Mi-26TM: Flying crane helicopter.
  • Mi-26TP: Fire-fighting version.
  • Mi-26TC: Export version of the Mi-26T.
  • Mi-26TZ: Fuel tanker version.
  • Mi-26T2: Improved version of the Mi-26T equipped with BREO-26 airborne electronic system, allowing it to fly any time, day or night, under good and bad weather conditions.
Mi-26 studied for potential role during Soviet Buran space shuttle program
Mi-26 was a brand new helicopter when it was explored as a possible means of transportation for the soviet Buran space shuttle.  "The developers of the Buran space vehicle programme considered using a couple of Mi-26 helicopters to "bundle" lift components for the Buran spacecraft, but test flights with a mock-up showed how risky and impractical that was."
source:  http://en.wikipedia.org/wiki/Mil_Mi-26#Buran_programme
quoting: Dr. Fedotov, V.A. "BURAN Orbital Spaceship Airframe Creation". Buran Energia. Retrieved 22 January 2013
http://www.buran-energia.com/documentation/documentation-akc-air-transportation.php
 
This type of use seems to be fairly risky for an operational use, and thus not applicable to understanding the Aotian-1 flight test.
     
Reminder about Mi-26.
On 05/11/2008, People's Daily Online News issued an article on China's then recent acquisition of two Mi-26 on the occasion of the Zhuhai 2008 airshow. Until then, "[T]he China Flying Dragon Special Aviation Company introduced the first Mi-26 helicopter in China in 2007 through a leasing arrangement. The company has now purchased it outright. The handover of the property rights was finalized at today’s ceremony,” said an official of China National Aero-Technology Import & Export Corporation.” This online article read that "The second Mi-26 helicopter in the purchase agreement will be primarily used for forest fire protection in Northeast China,” he was quoted as saying.

Still trying to connect the dots…  In the article below, CAS stands for "Chinese Academy of Science".


Qian Xuesen (11/12/11-30/10/09) was the father of the Chinese Space program. On June 12, 2009, CAS set up a "Qian Xuesen National Engineering Science Experiment Base". There seems to be a relation between this "Experiment Base" and hypersonic research. A simple googlesearch leads to a recently published paper (02/09/2013) by Michael Raska, Research Fellow at the Institute of Defence and Strategic Studies (IDSS), a constituent unit of the S. Rajaratnam School of International Studies (RSIS), Nanyang Technological University in Singapore. Quoting M. Raska:

"Hypersonic Vehicle Technology Project:
While data on China’s hypersonic research remains scarce, there are signs that China is developing conceptual and experimental hypersonic flight vehicle technologies such as hypersonic cruise vehicles (HCV) capable of manoeuvring at Mach 5 speeds (6,150+ km/h), and flying in near-space altitudes. Andrew Erickson, Associate Professor at the US Naval War College, analysed China’s Shenlong (Divine Dragon) spaceplane project, including its apparent test flight in 2011 and noted subsequent profusion of Chinese research articles on the subject. Similarly, Mark Stokes from the Project2049 Institute identified new research institutes focusing exclusively on the design and development of hypersonic test flight vehicles, including the 10th Research Institute also known as the Near Space Flight Vehicle Research Institute, under the China Academy of Launch Technology (CALT) - China’s largest entity involved in the development and manufacturing of space launch vehicles and related ballistic missile systems. The Qian Xuesen National Engineering Science Experiment Base in Beijing’s Huairou district is also one of China’s key HCV research centres."

... also available from here: http://www.nationmultimedia.com/opinion/China-expands-its-secret-civil-military-projects-30214208.html


Another article was recently published in the same "spirit" targeting a much wider audience (Popular Science):
Peter W. Singer (Director 21st Century Defense Initiative, Senior Fellow in Foreign Policy at the Brookings Institution), "Inside China's secret arsenal", Popular Science, December 2012, accessed online from:
http://www.popsci.com/technology/article/2012-12/inside-chinas-secret-arsenal

These papers occasionally balance and comment little piece of news regularly published on Chinese internet "source" such as:
"On September 3, 2013, Huanqiu, the Chinese edition of Global Times, published an article titled, “China Works on Three Big, Secret Military Projects? Divine Light and High Energy Weapons.” China’s National High-Tech Research and Development Program (the 863 Program) has vigorously worked on three types of mysterious military and civil dual-use high-tech research and development projects: 1) high power laser weapons development; 2) hypersonic aerobatic technology; 3) the 2nd generation “Beidou” satellite navigation system."

Project 869: CALT Tianjiao-1 proposal and Aotian-1.   .   .  .  . . . . .....  connecting the dots?

Early information on Aotian-1 hinted at some sort of connection between this vehicle and the US Dream Chaser project. As already stated, we could even go back 50 years earlier and start this story with Gleb LL's SPIRAL program... Let's call this the hypothetised form factor.

One possible lead was given in mid-2011 by Richard D. Fisher, a well-known US analyst with an expertise in Chinese affairs.

Ready? Let's go.


In the summer of 2011, R.D. Fisher released a series of slides presenting his vision and understanding of the Chinese Space Plane program, which I'm sure could have been better dressed into subtlety. Fisher's presentation bears some interest today as it explores the connection between state project 863 and manned / RLV efforts. Quoting Fisher's study: "At about the same time [1986] the Air Ministry, sensing opportunity, starts its “869 Project” which advances space plane concepts to meet the goals of the 863 Program. This preference reflects their desire to compete with U.S., Soviet, French and Japanese space plane programs. A key Chinese historical article* about this period makes clear that the Air Ministry was guided in particular by the military potential of space planes, to include consideration of space combat missions."

The historical article of interest wherein key information was extracted from, is: Li Chengzi and Zheng Xiaoqi (Beijing University of Aeronautics and Astronautics), “The Debate Over Placing Priority on the Space Shuttle or Manned Spacecraft During Consideration of China’s Manned Space Program,” Science and Technology Review, Submitted August 2009.

One slide of interest details CALT's "Tianjiao-1" proposal for project 869: a 20-25 t mini-shuttle launched atop a carrier-rocket. The original vehicle's basic aerodynamic shape is very classical. However, a later (2009) conference artwork (see picture) shows what may have been flown tested on september 20, 2013. Quoting R.D. Fisher again: "Possible lifting body based derivative featured in artwork for 2009 Chinese conference."

source: Richard D. Fisher, "China's Space Plane Program", International Assessment & Strategy Center, strategycenter.net, 24/08/2011,

http://www.strategycenter.net/docLib/20111024_ChinasSpacePlaneProgram.pdf

Images speak for themselves.

Let me be clear, however. The connection between RD Fisher's interpretation of Tianjiao-1 and the "2009-Chinese-HL_20-lifting_body-conference-artwork-picture" (sorry guys for this expression), still needs to be clarified. Until now, the connection still is an unproven hypothesis.

Thus if anyone could pass on this message to R.D. Fisher, with whom I never met, that's be great: Dear mister Dick Fisher, would you please actually connect the dots to get a better understanding. The connection between Tianjiao-1 and the 2009 artwork is not proven, just an overworn argument of authority. I'm sure this message will edge its way through…

 :) :P ::) ;) ;D

This figure matches with the payload performance of a Russian-made Mi-26 helicopter for either a drop test or crane takeaway on a desert airfield after drop testing from a modified Il-76. Maybe we should look into that, too.

As a result, Aotian-1 weight would fare a maximum 20 t, not 25 t. Maybe the weight envelope was downsized to 20 t sometimes during the program, as a consequence of iterative AOA studies in the design engineering process, taking into account both China's "future launcher" performance capabilities AND performances of available vehicles required to test the vehicle. To my understanding, allocating resources to develop -- as part of a separate, parallel program -- a new helicopter capable of lifting 25 metric tons would take too much time, add up risks. And the market for this new "would-be" would nichy, if not purely experimental. Chinese people are very pragmatic. Easier to buy and old working model from Russians. Less expensive. Enabling fast track effort.

The number of potential sites where the test flight supposedly happened is limited to 30 Air Bases of interest including the Dingxin / Shuangchengzi AB which has a special missile testing unit.

Dingxin is not in the same region.

Well... I'm not sure this is the one we're looking for. But thx for the piece of information, since this would be a likely place of choice to flight-test any future reusable aerospace vehicle: just a few miles away from Jiuquan space launch center! What may lack is a long, long, long runway.

Special to SPF member, wild bunch of information:
  • General "Dingxin airbase, located in north central China near the Shuangchengzi missile test range, is home to a great deal of PLAAF flight test efforts. Pockmarked terrain and targets marked in the desert indicate that among other things, Dingxin is home to weapons integration testing.
  • Nearby cities: Jiuquan, Jiayuguan City , Zhangye
  • Coordinates:  40°24'6"N 99°47'29"E
Thx for looking.

BTW,  for those newbies who come and go and revisit those Aotian-1 pages, be kind enough to revisit them even more regularly as I keep modifying my already posted texts to make sure I always get more accurate.

It would be interesting to determine which type(s) of Mi-26 was purchased by China, ands which was used during the september 20, 2013 flight test.

Short anwer: Mi-26TC "Halo".
Around 300 variants and subvariants have been produced since it first flew on december 14th, 1977 in Russia (prototype). This helicopter was declared operational in 1986. As of today, and to the best of my understanding, China is currently using 3 (three) Mi-26TC. In 2010, purchasing a 4th one, was also considered. It is also my understanding that some sort of joint venture later promoted the (seemingly ongoing) joint development of a 33t heavy lift helicopter.

- - - - - - - - - - - -

"In March 2010 Rostvertol plc and Lectern Aviation Supplies Co. Ltd (China) signed a contract on delivery of a new Mi-26Tc helicopter to China. This is already the third Mi-26TC sold to the People’s Republic of China. The same as the first two helicopters the third Mi-26TC is being purchased mainly for extinguishing fires and liquidating consequences of emergency situations. The cooperation between Rostvertol plc and Lectern Aviation Supplies Co. Ltd is lasting for more than five years since the Rostov enterprise entered the Chinese market. In April 2006 during the visit of the Rostvertol plc specialists to China and agreement was signed between Rostvertol and Lectern Aviation on establishing a joint Russian- Hong Kong enterprise. In October 2006 such an enterprise was established – Rostvertol Helicopters China Limited – what substantially helped in promotion of the Rostvertol plc products in China. The first Mi-26TC (certified modification of the Mi-26T) was obtained by China Flying dragon Special Aviation Company in May 2008. Initially, in 2007, the helicopter was handed over for lease for a 3-years period, however the Mi-26TC showed its worth in extinguishing serious fires in the Chinese provinces, in transporting bulky cargoes and in liquidating consequences of earthquakes, and China Flying Dragon bought it out before the lease term expired. In November 2008 during the international air show China’2008 a contract on sale of the second Mi-26TC to the Chinese air carrier Qindao Helicopters Special Aviation Co. was signed. The helicopter was delivered to China in July 2009 where it is successfully used for extinguishing fires and liquidating consequences of emergency situations."

Mi-26T and certified Mi-26-TS ("low maintenance helicopter" which can be "serviced in field conditions") operate in the country, as highlighted by Russian Helicopters ("Rosverto"l) CEO Dimitry Petrov.

I still have no clue yet where any of these Mi-26TCs are kept in PRC.
Is there a suggested spotter community suggestion?

Beyond future alphanumerics: Aotian-1, Aotian-2... Aotian-10000?

Needless to say, the very fact there is a project or vehicle code-named Aotian-1 (遨天1号) implies that sometimes in the future another vehicle/project/whatever will show-up bearing another incremented figure name: Aotian-2 (遨天2号), possibly Aotian-3 (遨天3号), possibly Aotian-4 (遨天4号), Aotian-5 (遨天5号), and I could raise the bar till infinite, say... Aotian-10000 (遨天10000号) but it'd take too much time. For all those who wonder, I am not privileged to any information: what I'm saying is just based on pure logic. And yes indeed, that is super logic, n'est-ce pas? Future Aotian birds will either be a limited series of Incremental performance Growth Vehicles OR a full fleet of separate vehicles. Only time will tell.

It would be interesting to determine which type(s) of Mi-26 was purchased by China, ands which was used during the september 20, 2013 flight test.

Short anwer: Mi-26TC "Halo".
Around 300 variants and subvariants have been produced since it first flew on december 14th, 1977 in Russia (prototype). This helicopter was declared operational in 1986. As of today, and to the best of my understanding, China is currently using 3 (three) Mi-26TC. In 2010, purchasing a 4th one, was also considered. It is also my understanding that some sort of joint venture later promoted the (seemingly ongoing) joint development of a 33t heavy lift helicopter.

I still have no clue yet where any of these Mi-26TCs are kept in PRC.
Is there a suggested spotter community suggestion?

A.

There is indeed a dedicated spotter community forum with an expertise in helicopters, and jets, and any flying honeyjunk you wanna know about: http://jetphotos.net
This is where an 18-member (as of today - please check out this post date) self-proclaimed "China Aviation Spotter Group" (CASG) operates with the following relevant link:
http://jetphotos.net/members/viewgroup.php?id=61

Incidentally, this is where Chinese Mi-26TC "Halo" tail code numbers (identifiers) and pictures can be found in plain sight.

The 1st Chinese Mi-26TC "Halo" operated by China Flying Dragon Airline, is serialled B-7802 (tail code) with CN registration number #34001212619. Dressed in red, its main mission is firefighting and disaster relief operations.
http://jetphotos.net/showphotos.php?cn=34001212619

2nd Chinese Mi-26TC "Halo" operated by Qingdao helicopters, is assigned tail code B-7803 with CN registration number #34001212620
http://jetphotos.net/showphotos.php?cn=34001212620. It is painted orange with grey on the underside.
http://pic.feeyo.com/posts/556/5566701.html

3rd Chinese Mi-26TC "Halo" was flown to China on October 14, 2010 and delivered to Lectern Aviation Supply on Monday Nov 15, 2010. It is assigned tail code B-7807. Painted red like its predecessor Mi-26TC / B-7802, its primary mission is firefighting and disaster relief operations.

These hellos still rely on old style cockpit design, and do not use the BREO-26 glass cockpit available for Russian Mi-26T2.

Attached is an official photo of Mi-26TC B-7807 released in November 2010 when it was officially transferred to China. What distinguishes it from B-7802 is the "black area" on its sides.

... which is what makes it so... interesting!

Attached is a picture posted on Panoramio -- BTW a great site-- taken by [ferrari575] in february 2011 at Hulun Buir Hailar Airport (呼伦贝尔海拉尔机场), just one month after this airport was renamed (it was formerly called Hailar DongChang Airport). Worth noticing is Mi-26TC "Halo" B-7807 on site.

http://www.panoramio.com/photo/48413355

While this may be a great starting point, this by no means implies that:
  • any such helicopter was on site on september 20, 2013;
  • Aotian-1's alleged flight-test happened;
  • Aotian-1's alleged flight-test happened in Hulun Buir (region);
  • Aotian-1's alleged flight-test happened at Hailar airport;

To admit I would agree that Dingxin AB is the most likely base even it is much more away from Russia and located in the Lanzhou MR.

By the way there are - at least officially - not that many operational bases and in regard to Carlo Kopp I would prefer my own "sources", since the map is wrong (Map from James Lawrence published in my book "Modern Chinese Warplanes" (Harpia Publ.), p. 123)

Deino

Thx again Deino. I found an interesting map which maybe useful as a complementary tool.

Looking for sources of inspiration. The 2009 conference background poster "identified" by Richard D. Fisher, seems to be heavily inspired by an earlier OSC-NASA artwork commissioned for illustrating the Orbital Space Plane (OSP) program. While this US program "folded", the winged body orbital space plane* concept was later (2010) revived by OSC (it was then renamed Prometheus).

*Post edited to correct some typos. The first version of this post mistakenly used the expression "winged bidy aerospace plane". I was definitey exhausted when I wrote it. Now fixed!

It is clear based on his history of posting that `Henry Kenhman` is nothing more than a propaganda organ from the Chinese military simply using a fake French name on the internet to publish (pretend to 'leak') infos on Chinese military programs (their favorite method, go figure why...).
Like, ya... what are the odds that a `French blogger' interested in the Chinese military and space programs would write posts on both Pakistani army and Indian aerospace forums...  Ahem... (both are mutually excluding when it comes to the Chinese military programs)(just follow those for long enough counting the number of insults traded online to get yourself a headache and you will get the idea).
And besides, if he was a French aerospace buff, he would definitely not be posting at the right places. Never saw anything by someone using his name or nicknames on any of the forums i frequent. I would recommand he tries the Nasa Spaceflight Forum, then he might get an real audience (or get himself sidelined or kicked out of there real quick when they would find out his game).

Recently published, related information of interest (JDW, october 2013)  O F   U T M O S T   I M P O R T A N C E

"China is also pursuing a manned space shuttle programme, according to China Aerospace Science and Industry Corporation chairman Gao Hongwei. Gao was speaking on 25 September at the 64th International Astronautical Congress (IAC) in Beijing."

[snip]

"Prior to Gao's 25 September statement the most substantive revelation about China's space shuttle ambitions was made at the 2006 IAC, when two engineers from the China Academy of Space Launch Vehicle Technology described two space plane concepts."

[snip]

"Other Chinese sources have indicated that the Chengdu Aircraft Corporation was heavily involved in designing the small Shenlong suborbital space plane technology demonstrator and may be equally involved in follow-on space place programmes. Shenlong is similar in size to the Boeing X-37B and has made at least one suborbital test flight, according to Chinese reports that were confirmed by a Russian source."

It's super difficult to (re)connect the dots.
FYI, this is the first time this picture is ever posted outside of the Chinese web. SPF kinda scoop, hey!

Hi,

Though I'm not sure this is the appropriate thread, while being relevant, I found that on May 8, 2010 a prospective "model" of what an hypothetical future chinese space shuttle (phraseology tinted with a grain of salt) could look like was exhibited in Shanghai. This was during the World Fair. This maybe crap, and surely is. But rather than trashing this piece of information out, I am including this material herein, together with the source as it may later inspire someone or ring a bell.

Abstract:  A plasma sheath enveloping a reentry vehicle would affect on-board antennas performances greatly, especially the navigation antennas. This paper studies the effects of plasma sheath on a GPS microstrip patch antenna during a typical reentry phase. Utilizing the algorithm of time-domain finite integration, the radiation and admittance characteristics of the GPS antenna coated by plasma sheath are obtained. The changes in antenna characteristics are analyzed and the process of a reentry blackout is also reproduced from the respect of the antenna performance degradations.

Hi, the article below is related to this current topic.

Emphasis (bold) are mine. I'd be grateful to anybody willing to fact check, and offer a careful and balanced view, related to this top-secret-military-test-interpreted-as-a-UFO information.

Be kind. Enjoy.

A.

BEWARE: FACT CHECK THE INFORMATION BELOW. CAN IT BE CONFIRMED IN ANY MANNER FROM/WITH OTHER SOURCES (weibo, if it's not censored yet, etc.)



"China Developing Secret 'Space Bomber': Duowei"


China is allegedly developing a secret "space bomber" to compete with America's Boeing X-37 reusable unmanned spacecraft, reports Duowei News, an outlet run by overseas Chinese.
Sources say people who reported UFO sightings on March 13 in the Chinese cities of Chongqing, Kunming, Chengdu, Wuhan, Changsha, Zhaoqing and Haikou actually saw a top secret rocket being tested by the government. This coincides with an announcement on the website of China's National Space Science Center the same evening which declared that scientists had successfully conducted a high-altitude scientific exploration test.
Various reports claim that China upped its space program following the successful launch of the US X-37B reusable unmanned spacecraft in December last year. Sources say China has been developing a mysterious space shuttle codenamed "Shenlong," meaning "Divine Dragon" in Chinese, a stealth space bomber that will significantly boost the country's space warfare capabilities.
Chinese military websites began "leaking" alleged photos of the Shenlong project in 2007, with a spacecraft appearing to be suspended from a Xian H-6 strategic bomber. In January 2011, a television station in northwest China's Shaanxi province reported the successful test of an aerosphere vehicle. However, precise details of the Shenlong have remained secret, with most online reports about the project deleted by censors.
Last June, media in central China's Hubei province said that the Shenlong is similar in purpose to the X-37B in that it is an unmanned spacecraft, and claimed that the country's scientists have achieved four major technological breakthroughs on the project in the last two years.
Speculation from alleged photos puts the Shenlong's size at around 1m high and 5m-6m in length, which would make it roughly a third the size of the X-37B. Others sources have estimated the Shenlong at around 1.1m high, 12m long and 4m wide.
According to speculative reports, the Shenlong is designed to be launched at 10,000m in the air from a Xian H-6 jet. The first phase engine will boost the 13-tonne Shenlong up to an altitude of 490 km within eight minutes, while the second phase will take it to height of 600 km. In the third phase, a 50 kilogram satellite will be launched into orbit before eventually descending back to Earth.

The 2009 conference background poster
.
.
.
.
.
.

taken on November, 14th 2009
.
.
.

... shows interesting details on he projection screens.

For what it's worth, and a question.
  • What we see is definitely not the Shenlong space plane (神龙”空天飞机) and does not match anything I know of.
  • The wing-body spaceplane is represented flying in space, with an attitude which could be interpreted as pre-rentry.
  • This raises a couple of legitimate questions: (1) is it a yet unidentified Chinese shuttle project/study/etc. and in that case, how well is it documented in the technical literature? (2) if not, it is another country's CGI image/artwork used/adapted here for "background" presentation and (gap filler) illustration only. In that case, what is the reference?
  • Hypothesis #1: This image may come from an animation movie. Can this hypothesis be verified? What is the dropdown menu used for? Launching the PPT (or its local equivalent) or a movie
  • Hypothesis #2: This image seems to be used as the opening slide of a plenary lecture. Can this hypothesis be verified?
  • As to what it being shown, I feel pretty comfident it's not an Indian shuttle project. Could it be Japanese? Russian? US? European?Very old? Brand "new" (well in late 2009)?
Come on guys and girlies, don't be shy... Does this image look familliar or ring any kinda bell? What is the closest equivalent you know of?

This is not to keep you from doing your research, but was only meant to say that as have been typical with the Chinese miltary aerospace programs, we will only know for sure and see the picture of what it was that was flown when they will decide to 'leak' it with one of their unofficial leakers, probably when a US Secretary of State or other dignitary will be paying them a visit, just to show off. Other than that, we are just seeing a lot of preliminary projects, illustrations showing proposals that will not look like the final vehicle if any, this all makes me think of the myriads drawings, illustrations and CG art we see from US aerospace manufacturers since decades about so many spaceplane projects. If the USAF indeed built a secret US space shuttle, we never saw it, and we may never see it until they decide to show it or long after it's been retired. Until then, we've got the not so classified X-37 B robot. The same way, none of the pictures shown here would be likely to show a classified Chinese space bomber the same way none of the drawings or photos we saw prior to the revelation of the J-20 were showing what the J-20 really looked like. If they had one they would not show it, even on the Chinese web. Too easy to see.

It would be absolutely weird if a missile launch would require evacuating towns and villages in several different spots, but I have no explanation on what on earth is that thing being launched right now (doubt it's aimed towards orbit though).

Expect UFO reports soon.....  ::)

Just found that [Elixir] / [Henri Kehnmann] news agency posted last september an intriguing CCTV13 video dealing with the future man-rated CZ-5 / CZ-7 launcher. The payload is a bit strange strange, and since I don't speak Chinese, understanding a little more goes beyond my reach.

Hi,

Here are some more contextual information for would-be fact-checkers:

(1) DATE / WEATHER

(1.1) DAY DATE
Aotian-1 alleged flight test supposedly happened on September 20, 2013 in the Hulun Buir region.
This was a Friday.

(1.2) DAYLENGTH
As to the Hulun Buir region, we can get local weather information associated with Hulun Buir's Hailar airport:
sunrise @ 05:45 local time
sunset @ 18:03 local time
day length: 12:18

source: http://www.sunrise-and-sunset.com/en/china/hailar/2013/september

Hi,

From a programmatic standpoint, most funds are channelled through both 863/super-863 and 973 projects.
Scholars could look into that.

Actually, quite a few 863 and super-863 [technology push] projects can be traced back to reusable aerospace technologies development.
Specifically, 863-70x series.  863-706 of course, but not only. 863-702 has been connected to RLV (TSTO) studies.

One among many interesting blog articles (largely cut and pasted on many various blogs) worth of interest is:
http://blog.renren.com/share/283319025/1844697075

There's a whole website about project 863 description and funding.

863 discussed on wikipedia:

863, as described by the Chinese Ministry of Science & Technology:

Article on Chinese hypersonics test:

http://freebeacon.com/china-conducts-first-test-of-new-ultra-high-speed-missile-vehicle/

Perhaps we should rename the thread to:  Gates, "They have prompt global strike...."

It's a MARV. Only about 50 years behind the US, and 40(?) behind Russia.

The question is whether it is powered (as the Russians have reportedly been working on), or whether it was "simply" a MARV.

Also, there is a huge difference between a Pershing II-type MARV and a boost-glide type vehicle, which this appears to be.

Yes indeed, Chinese hypersonics is in a very good shape.
And Project 2049's Mark Stokes may heavily downplay the extent of currently ongoing efforts.
Technical literature related to all aspects of this advanced weaponry (GNC, HTC, trajectory shaping, computation, etc.) clearly highlights that more projects are going on, full throttle up including various types of RLVs, and conventional and advanced high-speed airbreathing strategic platforms.

Is this fan art or an X-37 clone?

No idea yet but a question worth asking. This series of images posted on the Chinese blog, exhibits an introductory caption reading among others 神龙2.0 空天飞机CG which goggletranslates as "Shenlong 2.0 space plane CG". CG stands for "computer graphics". It looks like fan art but tastes like a real project. That's very confusing.
It puzzles me too. BTW, I find it hard to believe this "Shenlong 2.0" or orbital Sheniong, is Aotian-1 because it doesn't look like a Bor-4, or -- for those not familiar yet with this seminal Soviet-era project --, today's "Dream Chaser" (based on my understanding of what is going on in the field of hypersonics in China, as there are several projects going on).

China Confirms Hypersonic Missile Carrier Test
http://www.voanews.com/content/reu-china-confirms-hypersonic-missile-carrier-test/1830606.html
Reuters

January 15, 2014
BEIJING — China has flight-tested a hypersonic missile delivery vehicle in a move that was scientific in nature and not targeted at any country, the Defense Ministry said on Monday.
 
A Chinese military build-up has raised regional jitters. Many countries in Asia have welcomed a stated U.S. intention to shift more attention and military assets back to the region. They are beefing up military spending and ties with Washington.
 
“Our planned scientific research tests conducted in our territory are normal,” China’s Defense Ministry said in a faxed response to Reuters. “These tests are not targeted at any country and at any specific goals.”
 
The statement confirmed a report by the online Washington Free Beacon newspaper that the hypersonic glide vehicle (HGV) was detected flying at 10 times the speed of sound over China last week. A spokesman for the U.S. Defense Department told the newspaper it was aware of the test.
 
The Free Beacon said the test made China the second country after the United States to have successfully tested a hypersonic delivery vehicle able to carry nuclear warheads at a speed above Mach 10 - or 12,359 kilometers per hour.
 
Three decades of double-digit, annual increases in military spending have accelerated Beijing's ambitious build-up and allowed Chinese defense factories to boost the quality and performance of home-grown weapons and military hardware.

"House GOP Defense Heavies Slam China After Hypersonic Missile Test"
by Colin Clark on January 14, 2014 at 9:30 PM

Source:
http://breakingdefense.com/2014/01/house-gop-defense-heavies-slam-china-after-hypersonic-missile-test/

Quote
CAPITOL HILL: Sometimes it can seem as if one lives on several different planets at the same time while living here in Washington. This afternoon saw three top GOP lawmakers decrying China after it apparently tested (we don’t know if the test was successful) a hypersonic vehicle. This evening, the Navy announced it is beefing up the number of carriers stationed in the Pacific, moving the USS Theodore Roosevelt from its current berth at Norfolk to San Diego.

And the Chief of Naval Operations told the Surface Navy Association’s annual conference late this afternoon that the kerfuffle between the Chinese aircraft carrier’s escorts and the USS Cowpens “quieted down very quickly” once the carrier’s senior captain communicated directly with his colleague on the Cowpens. The CNO cast this as an excellent example of how well-understood protocols could help both sides avoid crises. It’s been previously noted that the captain of the Liaoning visited the Pentagon last September.

But on Capitol Hill, the portrayal of China was not nearly as positive. Three GOP members of the House Armed Services Committee, including chairman Buck McKeon, sounded the alarm.

The Chinese “appear to be leaping ahead of us” with the test of a hypersonic missile, said Reps. McKeon, Randy Forbes and Mike Rogers. “The Asia Pacific is fast becoming a powder keg. Allowing nations that do not share our respect for free and open avenues of commerce to gain a strategic advantage over the United States and her allies only brings us closer to lighting the fuse.”

I spoke with a former senior intelligence official who is familiar with hypersonic technologies to get some idea of the significance of the Chinese test. In military terms, this “isn’t very significant,” if it’s a gliding vehicle powered to hypersonic speed by a rocket, which appears to be the case, the former official said. The truly worrying advance would come if China had demonstrated the ability to fly a powered vehicle at hypersonic speeds that was able to engage in controlled flight. The United States has worked on hypersonic technologies for years, most recently on Boeing’s X-51, which is a scramjet. The X-51 flew faster than Mach 5 (which defines hypersonic) for 210 seconds in May last year.

There have been persistent reports that China’s so-called carrier-killer missile, the DF-21, is hypersonic. But it’s more likely a medium-range ballistic missile with an independently-guided warhead that does not fly faster than Mach 5.

Here’s the complex dance of the carriers as chronicled by the Navy News Service: “The U.S. Navy announced today that the aircraft carrier USS Ronald Reagan (CVN 76) will replace USS George Washington (CVN 73) in Japan and become part of the U.S. 7th Fleet forward-deployed naval forces (FDNF) in Yokosuka, Japan. As part of the rebalance strategy to increase the Navy’s presence in the Pacific Fleet, USS Theodore Roosevelt (CVN 71) will move from Norfolk, Va., to San Diego.

“Theodore Roosevelt will serve as a U.S. 3rd Fleet rotational carrier allowing Ronald Reagan to depart her current homeport in San Diego and proceed to Yokosuka. George Washington will depart Japan and proceed to Virginia in preparation for its mid-life refueling complex overhaul at Newport News Shipbuilding, Huntington Ingalls Industries.”

Yes of course as is the case when a new competitor shows up in the courtyard with a toy you were supposedly the only one in town, to own. Reminder: China invented gunpowder, had some practice in the art of tillery (pun intended), but they did not invent the gun nor the rifle. I should check back Needham on that, but this is what I remember from reading it a long time ago. This lack of engineering skills in an ever competing word (Europe) had dramatic consequences in the mid 19th century when europeans showed up. The Opium War is something every one should understand here, even if this is past. You just can't beat with knives and arrows a small army of gunmen, that's impossible, it does not make any sense. Chinese people learned this elementary lesson to avoid being caught by surprise in a similar situation, if anything "bad" happens. The problem reads differently today and becomes: when Vulcan's works give rise to infatuation and the feeling of limitless power, what do people do? I'm usually very positive but the future is not bright, quite the opposite. Very cloudy. Very dark. I don't understand everything but it's like everybody was currently, patiently paving the road to Hell. Everybody.

Hi.

New stuff? New stuff, definitely. Please read and help [Chinese-speaking anyone].

On 19/02/2014, [Sinosoldier] a junior member of sinodefenceforum.com, posted there [section: strategic-defense; subsection thread: China's space program news and views], what appears to be a [dead] backlink from where a couple of pictured text documents, originating from two different sources, are reposted for information. These chinese pictured documents are sanitized and edited for comments. These documents are seemingly associated with a "new type of space vehicle". The post reads that a '"new type of space craft has finished autonomous approach and landing tests".

unverified source [published 22/01/2014]: http://www.zznews.cn/news/system/2014/01/22/010230573.shtml
square one forum post [dated 19/02/2014]: http://www.sinodefenceforum.com/strategic-defense/chinas-space-program-news-views-184-1143.html

The only "known" chinese space craft recently discussed here around that could be able to perform / complete ALTs and thus match the succinct description, is a winged like vehicle such as, but not limited to, Aotian-1. If this is really it, things are going to move pretty fast.

So, here's a wrap up.

  • A new type of space vehicle is under development in China (this is not really a big surprise).
  • This new type of space vehicle is managed by CASC, not handled by CALT which has many consequences.
  • This new type of vehicle might be connected to Aotian-1 classified flight test, which happened in late september 2013. (If it were not classified, far more papers and pictures would have been published.) It may also be not, which is what I favor, as of now.
  • Aotian-1, based on information released and gathered at the time the subject came up, is a man-rated project from CALT while the "new type of space vehicle" involves lots of automation and originates from CASC
  • The new type of space vehicle might be an "extension" of CASC project 863-706 Shenlong
  • In early 2014, new information allegedly originating from CASC popped up on a chinese blog, NOT on any official CASC channel that I know of, as of now.
  • This early 2014 information, was then posted on a chinese defense related forum reaching a much wider, western target audience.
  • [Elixir], as always acting like an informal chinese aerospace defense news agency source, is back from their new year holidays and active as usual. Quite surprisingly though [Elixir] lagged behind this "announcement". [Elixir] postings on this subject, might be worth looking at.
  • The "new type of space craft" documents posted on the web in early 2014 contain sanitized code names, key words and expressions.
  • At no point does the code name "Aotian-1" appear in a legible manner in any of these documents.
  • Document forensics may also be of interest [QR code readings, etc.]
  • If anybody is available for translation, please help NOW.
Your move.

Hi there,


As to my previous post just above, and as a reminder, I do not think this all refers to Aotian-1 but rather to the actual , real-life version of this CGI-related material, identified by [Deino]:

As a consequence of some of the previously posted information herein and on other forums, here comes the first of a long series of topical articles begin to spring. It is very late, and these papers only scratch the surface of things. There is so much to say, to see, to tell.

On 22/02/2014  sinodefense.com forum member [DX] issued  a very incomplete article on "China's Spaceplane programme".

DX, "China's Spaceplane programme", 22/02/2014,
http://sinodefence.com/2014/02/22/chinas-spaceplane-programme/

For [DX], the author, this  subject is not new. Four years ago, in january 2010, he released a succinct review of "China's space shuttle programme in the 80's" partly built on Fisher's own reviews… 
http://sinodefence.com/2010/01/01/chinas-space-shuttle-programme-in-the-80s/


[Extract.]
Automated High-Speed Approach and Landing Test

A short, seemingly benign news article published on a local government website in early 2014 has, by accident, revealed that a highly secretive landing test of an unmanned spaceplane vehicle had been successfully conducted. The article, published by a department of the Fujian Provincial Government, praised the significant contribution made by a local enterprise specialised in bearings to the successful flight test of a “key aerospace system”. According to the report, the vehicle had completed an “automated high-speed approach and landing test”, marking the grasp of the associated core technology.Coincidently, the same flight test was also mentioned in an official Thank You Letter issued by CALT to Northwestern Polytechnical University (NWPU). The letter, dated October 2013 and signed by the programme director and chief designer of an “unmanned aerospace vehicle system”, praised NWPU for its work on an electrical braking system used by the vehicle. The name of the programme was carefully blacked out on NWPU’s website. The letter claimed that the successful test of the unmanned vehicle not only enabled full grasp of automated high-speed approach and landing, but had also made a number of unprecedented achievements in the field of spaceplane both domestically and internationally. Although the exact type of the unmanned vehicle involved in the test is unknown at this stage, it can be assumed that the vehicle is somehow associated with the AoTian 1 development. Based on this progress, the vehicle is likely going to enter operational service by 2018-2020."[/size]

The Chinese Defense Ministry confirmed the fourth test of a hypersonic nuclear delivery vehicle, which the US called an “extreme maneuver,” amid rising tensions between the two powers in the South China Sea.
The test of the hypersonic glide vehicle, which the US has dubbed the “WU-14”, was carried out on June 7 and is the missile’s fourth test in 18 months.
"The scheduled scientific research and experiments in our territory is normal, and those tests are not targeted at any country and specific goals," the ministry said in response to a report published on Thursday by the Free Beacon.
The strategic strike weapon is extremely advanced and can travel at 10 times the speed of sound, or 12,231.01kph.

http://rt.com/news/267115-china-tests-hypersonic-missile/

Quote
A fourth test of China's ultra high-speed hypersonic glide vehicle for nuclear delivery called the WU-14 was carried out by the People's Liberation Army last week, Bill Gertz, senior editor of the Washington Free Beacon, wrote in an article published on June 11.
Gertz said the test was conducted on June 7. As this is the the fourth test of the WU-14 in the past 18 months, US intelligence analysts believe the PLA has set a high priority on the development of the vehicle. The first WU-14 test is understood to have taken place on Jan. 9, 2014, followed by further tests on Aug. 7 and Dec. 2. All four tests have been conducted at the same facility in western China, the report said.
A US intelligence official told Gertz that in the latest test the WU-14 demonstrated for the first time the "extreme maneuvers" designed to penetrate US missile defense systems. The WU-14 threatens to neutralize US strategic missile defenses with the unique capability of flying at ultra-high speeds and maneuvering to avoid detection and tracking by radar and missile defense interceptors, said the official.

Hi there since we don't have any WU-14 related thread, which might be considered useful now, this one may serve as a repository for hypersonic related research in China, and we shall see later.
AOTIAN-1 is not WU-14 anyway, not funded by the same organizations.
There are many other hypersonic RDT&E projects in PRC. This forum hasn't discussed much whar was going there in the field of hypersonic airbreathers : ramjet, scramjet, DCR etc. for claimed defense and/or aerospace (RLV) applications. 
Yep. Many projects often changing names…

The number of potential sites where the test flight supposedly happened is limited to 30 Air Bases of interest including the Dingxin / Shuangchengzi AB which has a special missile testing unit.

Dingxin is not in the same region.

Question.

Anybody having leads on PRC's hypersonic flight ground test facilities, achievements, plans, projects, university and industry teams? A lot of information is available but it seems we don't have this kind stuff posted on this forum yet. That for sure would be a nice repository. No ground test. No flight test. So.

Hi. Slightly off topic but not so much as it pertains to the ease of access to Chinese S&T litterature. And I'll be careful enough to loop the loop and weave it back to the topic. 

Below is a screenshot of the nodal architecture of Chinese scholar's IS, for each academia article published on any subject of interest. It also extends to patent literature, blogs, websites, PhDs theses manuscripts, etc. It is quite impressive.
 
For those who do not understand the power of a centralized "communist" economy, this sort of information system (IS) cannot exist in any other not-centralized system -- to the best of my knowledge, of course. Everything published is sucked up and indexed in an orderly, nodal referenced system.

This information system was dreamt of by Tsien Hsue-Shen in the early 1980s, as described by Iris Chang in her biography of this father of the contemporary chinese space rocketry. getting back to our thread, Tsien was key to evaluate Sänger's report on the Raketenbomber (WWII's spaceplane bomber concept) and came up with the new field of study: superaerodynamics (hypersonics in rarefied dynamics.) Tsien was von Karman's protege. Looping the loop, hey!

Re: the magnetic windows and other systems designed to allow antennae and sensors to operate during re-entry, would they most likely be for command guidance or for onboard sensors to inform onboard decision making? Obviously they aren't mutually exclusive, but would you expect most of the tracking updates to come externally? How much intelligence would you pack in something like this?

Would it have much use as a high speed re-taskable recon platform if the plasma blackout wasn't a problem? Have to wonder if some of the US recon analogues had similar systems, copper canyon and the like.

Hi back;

Most open, and easily available Chinese S&T literature discussing or tackling those subjects always quote recent US papers on blackout mitigation, as well as a series of NASA conference proceedings dating back to the 1970s (fact check this, my memory might fail) which you can all download from DoD's DTIC website.

The questions you ask are short but pertinent; they require, however, complex answers and echo ViceNews' recent article (well, the title is self-explanatory, contents is a bit below their publishing standards IMO):

You may use blackout mitigation (BM) techniques to (try to) open specific windows for specific bands which would be designed for telemetry or GN&C only. Many reference books on hypersonics authored by Chinese scientists are now available. One of them, published in 2012, might help you:

[/list]COPPER CANYON? Well, I don't know if anything on BM has been studied / published on/for this early 1980s SSTO RLV system predating US NASP. I'd first try to investigate another line such as a still little-known mid-1980s hypersonic boost glide vehicle program called "HAVE NOT" which was cancelled at some point, to the best of my knowledge (it would be rather surprising these BM issues were not studied at the time.) For sure, US hypersonic efforts are inspirational for Chinese prospective weaponmakers; so looking at what's available on one side of the Pacific Ocean is helpful to understand what might serve as guidelines on the other side. Example of an interesting hypersonic patent-related analysis from a little known institute (Beijing Seahawks Science and Technology Information Institute):

  • Li Yelan, Bai Yang, Zhou Peng, Patent Analysis of the Course of Aerojet's Business and the Key Technologies of Hypersonic, Procedia Engineering, Volume 99, 2015, pp.773-779: Proceedings of the 2014 Asia-Pacific International Symposium on Aerospace Technology, APISAT2014 September 24-26, 2014 Shanghai, China. Abstract: This study researched the patents published from 1942 to March of 2014 of Aerojet Company (including Aerojet Rocketdyne Company's patents) in USA, considering Aerojet's annals and other information, analyzed relationship of the patents and the course of Aerojet's business development, and the technology R&D process, and extracted the key hypersonic technologies of Aerojet Company, at last raised the conclusion. Source paper: http://ac.els-cdn.com/S1877705814037151/1-s2.0-S1877705814037151-main.pdf?_tid=9157c328-35b9-11e5-a700-00000aab0f6c&acdnat=1438150862_462d3046fb4571f6e39fbefb9509cb9f
Chinese S&T literature is replete with -- hundreds of -- RLV reentry/guidance papers such as:
  • Ping Lu, Entry Guidance and Trajectory Control for Reusable Launch Vehicle, J. Journal of Guidance, Control, and Dynamics.1997.20(1):143-149
  • Ping Lu, Predictor-Corrector Entry Guidance for Low-Lifting Vehicles, J. Journal of Guidance, Control, and Dynamics.2008.31(4):1067-1075.
  • J.B. Wang, Y. Tian, Z. Ren, Mixed guidance method for re-entry vehicles based on optimization, J. Journal of Beijing University of Aeronautics and Astronautics.2010.36(6)(in Chinese).
  • G. Chen, Study of reentry guidance and terminal area energy management for lifting vehicle, D. Harbin: Harbin Institute of Technology, 2011(in Chinese).
  • Q. Wang, M.P. Ran,Y. Zhao, Re-entry guidance for hypersonic vehicle based on predictor-corrector method, J. Journal of Beijing University of Aeronautics and Astronautics. 2013.39(12):1563-1567(in Chinese).
Lastly, there is a lot of homework required to answer your question. Chinese scientists regularly organize expert-level conferences on GNC and tracking such as the China Guidance, Navigation and Control Conference (CGNCC), described as "the largest academic conference on the guidance, navigation and control of aeronautical and astronautic flying vehicles in China" (CSAA website). This conference is organized by the CSAA's Technical Committee on Guidance, Navigation and Control (TCGNC) and here's a recap of past and planned conferences where BM and hypersonic-related GNC has been (and will be) discussed:

  • IEEE CGNCC2007 > 2007 Chinese Guidance, Navigation and Control Conference - 3-5 November, 2007, Beijing, China
  • IEEE CGNCC2008 > 2008 Chinese Guidance, Navigation and Control Conference - 14-16 November, 2008, Xi'an, China
  • IEEE CGNCC2009 > 2009 Chinese Guidance, Navigation and Control Conference - 13-15 November, 2009, Beijing, China
  • IEEE CGNCC2010 > 2010 China Guidance, Navigation and Control Conference - 9-10 October, 2010 - Shanghai, China
  • IEEE CGNCC2014 > 2014 Chinese Guidance, Navigation and Control Conference [2014中国制导、导航与控制学术会议] - Yantai City (烟台), Shandong Province -  8-10 August 2014
  • IEEE CGNCC2016 > 2016 IEEE Chinese Guidance, Navigation and Control Conference - Yantai City (烟台), Shandong Province (originally planned in Nanjing, Jiangsu Province) - http://cgncc.buaa.edu.cn/
It's always helpful to get an integrated, system, contextual (over)view. What type of system-level architecture would be necessary to allow any such retargatable system, etc. Terminal guidance with low CEP is not something I've gone into yet, since it's RLV-off topic in this current context.

A.
PS) I try to keep updating the reference paper list  in every related post which I often edit. Hope this helps.

Hi.

For what it's worth, and looking back again and again at Aotian-1 story, against other several chinese "winged" reentry projects (Shenlong, Wu-14, etc.), something annoys me.

In january 2014, at least one chinese media outlet gave away pieces of information on a flown-tested reentry vehicle, identified as a CALT project which I suspect to be Aotian-1. I did not grab this information on time, and here is the (empty) available URLs:

http://www.fjgzw.gov.cn/ar/20140124000003.htm

It seems that the official website of the Chinese city of Zhangzhou (漳州) released some sort of statement implying that a "high speed autonomous landing test" had been performed. The reason why the city would have released any such information was (partly) to boast of a city-based company's achievements, implied on the project. This (yet-unidentified) company might have been in charge of designing or manufacturing the vehicle's body flaps. I'll try to check things out in this, when I have more time.

A.

PS) I am very careful here because this information comes from an only recently identified "old avatar" of the ever-talkative "Henri K." organization though under another alias, as always. So, let's see where this all goes. And for those who do not see the point of this footnote, please read the PS of my very first post in this thread to get a better contextual understanding of the picture. This is of particular relevance today.

Hi again.

Something odd happened on the French aerospace forum "FCS" (Forum de la conquete spatiale) on the Space China section  wherein [Henri K] aka [ELIXIR] released what seems to be highly confusing but high-value pieces of information on the still secret Aotian program. Newcomers are urged to read carefully the footnote of my first post here in this thread to get a better understanding of the context. And be aware that, to the very best of my skills and knowledge, there is/was no such equivalent open China source discussing strategic aerospace, defence and advanced weapon systems on western forums. Some time ago, [Elixir] warned his audience he was suffering and that he would post for the last time; then he returned, then we are left in the dark…

So here we go, again:

http://www.forum-conquete-spatiale.fr/t16416-information-avion-spatial-ao-tian-1

According to [Elixir], a series of patents filed by CALT in October 23013, showcases a winged spacecraft which he relates to Ao-Tian. These patents clearly show a spacecraft structure and structural elements which could be associated to a Chinese version of X-37B, which in turn would be distinct from Shenlong.

This is old news but puzzling anyway. Until now, my strongest belief was that Aotian was a lifting body. My only guess is… I don't know and I feel a bit confused, although I do have some ideas.

I am attaching herein "as is" elements posted by [Elixir]. They really are interesting but dots still need to be connected very carefully. Something's not right. (Or I was made to make analytic mistakes, in the past which is not good.)

Hi.

Something else of interest popped up from a July 8, 2012 online article discussing, among others, Chinese work in an (alleged) orbital bomber project  (I prefer to be careful) while browsing baidu image with the following keyword: 遨天一号

Picture extracted from:
http://fxb.591hx.com/article/2012-07-09/0000055663s.shtml

This is weird. I really missed this image, and wonder both the context, and why markings are in English (something BLACK).

Anyone? Guess what?

Hi.

Something else of interest popped up from a July 8, 2012 online article discussing, among others, Chinese work in an (alleged) orbital bomber project  (I prefer to be careful) while browsing baidu image with the following keyword: 遨天一号

Picture extracted from:
http://fxb.591hx.com/article/2012-07-09/0000055663s.shtml

This is weird. I really missed this image, and wonder both the context, and why markings are in English (something BLACK).

Anyone? Guess what?

That photo with "black" looks like "jet" maybe the first part, plus the colour scheme and the fern leaf would point toward some sort of New Zealand link  ;)

Going back and forth to original information, which I still try to piece up together when I have time.

NWPU was said to be involved in the alleged 2013 flight test. For which we now have a related, published TAEM patent (late discovery, I know). TAEM stands for "Terminal Area Energy Management", and is commonly associated with gliding, shuttle-like landing phase ops. So in more than a way, this happens to be an interesting patent, really.

A.

Geometric-programming-based gliding aircraft terminal area energy management trajectory planning method
Patent No. CN104714553 (A)
Inventor(s):    ZHOU JUN; LU QING; WANG HUAN; HU WEIJUN +
Applicant(s):    UNIV NORTHWESTERN POLYTECHNIC +
Application number:    CN2015118082 20150114
Priority number(s):    CN2015118082 20150114
Abstract:  The invention discloses a geometric-programming-based gliding aircraft terminal area energy management trajectory planning method which is used for solving the technical problem that an existing gliding aircraft terminal area energy management trajectory planning method is poor in practicability. According to the technical scheme, on the basis of the state of an aircraft entering a TAEM section, a geometric programming method is utilized for rapidly planning a reasonable and feasible TAEM plane trajectory; on the basis of the TAEM plane trajectory planning, height deduction is performed, and therefore a complete trajectory planning strategy is given. Due to the fact that the aircraft enters an entry of an automatic landing section in a spiral-line mode in the geographic planning process, the sudden overload change phenomenon is effectively avoided, and therefore the requirement for the aircraft maneuverability is lowered; meanwhile, during trajectory planning, the state of the aircraft at the TAEM section at the initial moment is considered, corresponding flight paths are planned in a classified mode for the entering state of the aircraft, the reasonable trajectory can be rapidly planned, the requirements for different entering directions are met, and the planning speed is high through simulation verification.

Also, as an attached image, interesting RLV shape from another Chinese TAEM patent…

Hi.

Many things, here, in this thread:

http://bbs.9ifly.cn/forum.php?mod=viewthread&action=printable&tid=13234

with loads of original references to Aotian-1 related material published in Chinese literature.

Of particular interest here (in this bbs.9ifly thread) is a pretty active Chinese forum member, [IGNIX]. Who ever uses this alias investigated on his own Aotian-1, and periodically listed all CALT patents of interest likely associated with this semi-classified CALT reusable aerospace shuttle project (it were classified, patents would never have been released by patent military censorship, as in any other country). Some of this collected material was most likely used by [ELIXIR] (see my first post footnote on this team) to make this information partly available on French aerospace forums, and to certain extent, defintels.

Because I feel this Chinese link given above -- which had, until now, escaped my attention (yep s… happens!)--, is of utmost importance, I am reposting here significant pieces of information extracted from it, for other SPF researchers or interested parties.

Be aware that [IGNIX] organized patent lists by inventor names, which is another clever way to look at things. He thus identifies key researchers and project managers occasionally mentioned in news articles, blogs, grey lit, etc. [IGNIX] latest update dates back to May 5, 2016 and included some patents screengrabs herein attached.

Enjoy.

Hi.

Quite unclear yet but…  Given CALT's Aotian program pace, it maybe that a space-rated variant of this vehicle could either be tested at hypersonic speeds later this year, or flown into space. This is still very unclear: hints that something WILL happen this year started to circulate in late February / early March 2016.

Another, alternate possibility is that an "upgraded" Shenlong shows up later this year for a spacebound mission. Again, this is all very unclear since both projects (Aotian-1 and Shenlong), though competitors, might also be connected to an extent I haven't been able to determine yet. So take all this post with a tiny grain of salt. Again, this is my two cent forecast, not factual information, certainly not an announcement. Just thinking loud and clear in this almost voiceless thread.

A hint of what may happen might be found in CALT's RLV roadmap unveiled in 2006 at the International Astronautical Congress (IAC) in Valencia, Spain. Next move should be a Mach 15 flight test, with demonstrator launched atop 1st stage rocket. Something like ISRO's recently held RLV-TD test but  significantly different: Chinese work hard on the ability to head back to launch site or glide back and land safely on a strip, and this is quite different.

A.

PS) Another paper of interest is: Yang Yong(R&D centre,China Academy of Launch Vehicle Technology,Beijing,100076);"Study on Roadmap of Chinese Reusable Launch Vehicle"[J];Missiles and Space Vehicles;2006-04 // abstract: Reusable launch vehicle(RLV) is a main development trend of space transportation system.As the expendable launch vehicles are more and more mature,many countries have paid more attention to RLV concept and its’ key technologies.The state-of-the-art and the development trend of RLV is analyzed and a road map of China RLV technology development is presented.

Great find Flateric. Really.

This image which leaves more questions than answers, and seems to confirm something actually happened 3 years ago (I never doubted that).

The Aotian-1 vehicle is not pictured.

What we see here, a now fully identifiable landing tail-numbered Mi-26 TC, lifting a red-colored (empty) support structure connected to a lagging, white, unfolded stabilizing parachute.

Contextual analysis
  • The still image is likely extracted from a video from: https://www.weibo.com/u/2032349831 (to which I have not been able to connect for lack of security)
  • A Chinese twitter account image is used for caption, and reads:
    "遨天一号/Aotian-1】2013.09.21 高速自主进场着陆飞行试验。可能是类似X-37B的一种小型航天飞机"
  • This Chinese caption roughly googletranslates as:
    "2013.09.21 speed autonomous approach and landing flight tests. X-37B may be similar to a small space shuttle."
  • This twitter caption implies Aotian-1 is a possible direct response to the US, military-grade X-37B.

Maybe this celebration means Aotian-2 is already on its way…Maybe we hear about Shenlong in a couple of weeks…

Thx as always.

Hi. This is very important news.

The proselyting [Elixir] organization has announced very late, on September 28 2016, on the French "formum de la conquete spatiale" (FCS), that China had likely flown tested in the Gobi desert, one of its aerospace hypersonic demonstrators, be it Aotian or Shenlong (which seems to have been flown tested MANY times anyway). This piece of information was filed on FCS in the " Avion Spatial "Ao Tian 1"  " thread, here:
http://www.forum-conquete-spatiale.fr/t16416-information-avion-spatial-ao-tian-1

Added. The very same information was initially published by the [Elixir] organization on Sept.24 on another French military forum, "Forum marine", in the hypersonic thread here:
http://forummarine.forumactif.com/t7274p75-information-developpement-des-technologies-hypersoniques
(This had escaped my attention, at first.)

The [Elixir] organization base their information on NOTAM analysis, among others.

To access the [Elixir] organization review article / announcement on their newly-created website, users must be registered and logged in.

A few months back, [Elixir] anticipated that something would happen along these lines, teasing their audience…

Please please please China watchers, help me fact-check, review, confirm this event. Fact-checking is KEY. Thx.

A.

PS) Wow, I look back at my Sept 25 previous message and quite honestly, I did not expect that such an event would happen so soon; but there were so many indicators and warnings (I&W).

Hi there,

China seems to have flown tested, once again, it experimental airbreathing hypersonic vehicle.

Info posted on this other China AVIC hypersonic vehicle thread:
http://www.secretprojects.co.uk/forum/index.php/topic,27943.0.html

Alltogether (various programs), this would make 4 hypersonic flight tests in October 2016, claimed by the [Elixir] organization!

LATER EDIT

Back onto the trail of Aotian,

Another piece of the jigsaw.
Here is a CALT patent which might be related to either Aotian-1 or a space rated yet to be flown (Aotian-2 for lack of better designation).

Patent title: Mortise and tenon type wing rudder structure suitable for reentry vehicle 
Patent No.: CN105416566
Issued: 2016-03-23
[abstract]: A mortise and tenon type wing rudder structure suitable for a reentry vehicle comprises a framework (1), an upper side skin (2), a lower side skin (3) and fixing end covers (4), wherein the framework (1) comprises a wing beam, a rear longitudinal wall, stringers and ribs and is of a grid type framework structure; the upper side skin (2) and the lower side skin (3) cover the upper portion and the lower portion of the framework (1) respectively; the front edge ribs are distributed between the front edge of a wing rudder and the wing beam; openings used for installation of connection hanging shafts are symmetrically formed in the front edge of the wing rudder; the fixing end covers (4) are installed at the openings, perpendicular to the wing beam and connected with the upper side skin (2) and the lower side skin (3); the end wing ribs, the middle wing ribs and the fixing end covers (4) are connected with the upper side skin (2) and the lower side skin (3) through mortise and tenon connection structures. The structural mass of the wing rudder of the reentry vehicle is reduced through the mortise and tenon connection mode, and the thermal bearing capacity is improved.

EDIT Based on other patents of interest (CN105205281) this specific patent describing a "wing flap" could actually be related to another CALT project / program which could be patterned after Europe's PRE-X atmospheric reentry experimental lifting body vehicle.

Hi,

There seems to be a "new" organization in charge of studying RLVs, "space aircraft", "aerospaceplanes", etc. in China.

This organization is teaming up with CALT, but distinct from it.

This organization is called the "Beijing Linjin Space Aircraft System Engineering Institute".

A.
EDIT/ The organization is not new. See my msg293385 below.

Hi,

I did some little more homework on that. The story goes, as far back as I could determine, to 2008. On the basis of information I was able to pieced up today. This(these) institute(s) might have been created earlier, i.e. prior anything is published.
I did not investigate further down Chinese blogs, etc. Only industry-related literature.

2008: BEIJING SPACE AIRCRAFT DESIGN
2010: BEIJING NEAR SPACE AIRCRAFT SYSTEM ENGINEERING RESEARCH INSTITUTE
2011: BEIJING SPACE AIRCRAFT OVERALL DESIGN DEPARTMENT
2013: BEIJING LINJIN SPACE AIRCRAFT SYSTEM ENGINEERING INSTITUTE

To conclude: I was wrong in my quoted post; the aerospace R&D institute remains very active, but it is not really "new".
One of its areas of expertise, as it seems, is sensor integration and attitude control on hypersonic/reentry vehicles.

BTW, and for those who care, there is another R&D institute, that might be related (with a specialty in CAV-like systems, such as the so-called DFZF):

2011: NEAR SPACE INSTITUTE FOR AIRCRAFT SYSTEMS ENGINEERING

Nice find BobbyMike. Thx.
Gives a larger, picturesque contextual understanding of the hypersonic equation.
However, this is DF-ZF (strategic boost-glide) material, not Aotian (reusable spaceplane) related.
Of course, and as it sometimes happens, cross-competence and transdisciplinary work required to keep things rolling, actually blur what appears distinct at higher visible levels.

Based on....?  Unless we are have been flight testing hypersonics deep in the pacific, far away from conus, there hasn't been anything hypersonic picked up by seismology stations since the space shuttle except the x37. Hiding a fighter sized stealth aircraft in the desert is one thing, but people would notice something traveling at mach 6 and high altitude for many miles. Doing hypersonics in a black world, unknown, is next to impossible if not impossible. Could you imagine a blackworld x-15 darting around at 300k and 6 mach? No way.

Drop the hyperbole. We have more hypersonic experience than all the countries of the earth combined. In the white world we flew a hypersonic aircraft for decades; It was known as the Space Shuttle and it performed a large amount of hypersonic research during re-entry.

  • as long as all they ask me about is the air war...
The question is ram and scram Propulsion, almost everyone can create a ballistic reentry vehicle, that dors not a hypersonic program make.

After doing some research my initial conclusion is that lockheed at least has variable geometry combined RAM/SCRAM engines with shock intersection and pressure induced combustion. This is based on what I've seen on the state of the a art in white world testing and more importantly the soft of papers bring turned out on hypersonic wind tunnel data and CFD.
I have US operational hypersonics research, for practical best term aircraft in AIAA papers going back at least 30 years and tentative cuts they point to test craft, ground based proof of concepts with long term positive results and web hints at previous operational aircraft, though they are obviously careful to avoid that as you don't get redactions in these papers, but I've only just started going through them.

I think for a long time high stealth sub Sub sonics and maneuvererable satellites (themselves stealthy) with better sensors (hyperspectral, space based bi static SAR etc.) was where it was at. However the need for fast tasked ISR strike platforms just wouldn't go away and if they needed to bring the Blackbird bank for 91, you can see why they would need it blue more than ever seen Anti-sat and anti stealth work advancing so quickly with tier one adversaries.

Just saying you shouldn't be surprised to see some cool stuff get rolled out in the event if national emergency. It might not be glamorous like a Habu, but a long range sensor YAV, line the d-21? Maybe...

The Chinese prisms seen to be all over the place but that impression night be misleading, deliberately or not, or they could be funding anything that moves (over Mach 5).

Which is worth just slightly more than zero when it comes to sustained hypersonic flight.  Also, don't make the mistake of assuming that because we once did a thing (say, flew BGRV or ASALM PTV) that we could do it again (see the string of failures that pass for "success" in the US, or the habit of quitting at the first sign of difficulty - many times BEFORE the first sign of difficulty).  The Greatest Generation has retired, or died, and taken it's can-do attitude with it.  In the West anyway.

Sferrin, you nailed it. China is active in many hypersonic programs. More than half a dozen hypersonic shuttle-related projects are on the way. Because of their political-economy, based on the plan, they are very unlikely to quit.

Back to Aotian-1, now. We should soon hear of Aotian-2 or something along these lines...

The sheer determination to beat the Russians to the moon was beyond belief. While things may have slipped a bit since that time that same heart still beats among other Americans today.

Yeah I said it: Americans. Like you I also want more and would like to see those projects you mentioned come to fruition. But I am not bitter due to our lack of progress in certain areas.

Okay guys. If you want to discuss US technological supremacy and 3rd shift Apollo, there is the bar.

The context has changed. Tools changed. The global situation has changed and we all have to understand this. You cant think of today's situation framed in the past. We should get back to China's hypersonic aerospace / reentry topic.

I'm not like you. In those matters I stick to the facts and I am agnostic to understand what the hell is going out here. Wether you like it or not, China is making huge progress in various areas of hypersonics.

Back to the point. Thank you.

And regarding the 'can-do attitude' you claim has died in the west please make sure you qualify that you are speaking for yourself.

Yeah?  Where's Fasthawk? RATTLRS? HyFly? X-51 developments? LRASM-B? AARGM? ATKs MSST? What happened to follow on HTV-2 flights? US Army AHW? There are isolated exceptions to the rule (SpaceX and Blue Origin for example) but in the DoD? Please.  The only X-51 flight that was marginally successful (the last one) they ALMOST DIDN'T DO BECAUSE THEY THOUGHT, "WHAT IF WE FAIL?".   That's straight from the horse's mouth.  And what did they do with that glimmer of success?  Quit immediately.  "Whoa, that was scary.  Better not do that again, we might not get as lucky."

The advent of stealth, followed about 10 years later by the fall of the Soviet Union killed the need for speed. Many big ticket items were scrapped immediately after the demise of the USSR including the Virginia, the B-2, the Midgetman and others... That was the 90s. Then came 2001 and we know where defense spending went for the next 16 years. There has been no need for hypersonic weapons, and only now are we seeing things starting to get warm again with potential foes.

There were other more important weapons systems to modernize the military that were canceled to even be concerned about hypersonic weapons that were not needed.

Really?  So why all the failed programs then if they weren't needed?

I work in engineering on unspecified "vehicles", and I've been both a mechanical and electrical engineer. If you do not keep the talent pool "warm" with projects for the sake of maintaining first hand knowledge, then a given capability is truly 100% lost forever until it is reinvented. What you may call a failed project is actually a 'win' for maintaining experience and know-how. These failed projects are giving many engineers first hand experience and also making gains in knowledge over what was done in the past. Be thankful the US is keeping the talent warm until such time these weapons may be needed. We learn as much from 'fails' as we learn with the 'wins'.


Oops! In the above post I meant "seawolf" instead of "virgina"

The purpose was not to keep the pool "warm".  If they were interested in charity programs for that purpose they'd have been worried about not losing what we already had. (Nuclear weapon expertise, large solid motors, and ramjets for example.)  With these other programs, quitting at the first sign of difficulty only teaches how to produce failures.  They never get the chance to find out what actually works.  They just know what they did didn't work.  Doesn't sound incredibly effective to me.
