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
[list type=decimal]
[*]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.
[/list]

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. [size=10pt]This is very important news.[/size]

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.

It's a certainty that China will have Prompt Global Strike abilities WELL before the US.

Yes. But one has to balance this equation with some perspective. Much has happened in the US in the black world, seemingly.

Given the notable lack of success in the US in white world hypersonics, I'd have to say I highly doubt it.

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.

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...

"...Because of their political-economy, based on the plan, they are very unlikely to quit."

What if the 'plan' leads to a dead end? And regarding the 'can-do attitude' you claim has died in the west please make sure you qualify that you are speaking for yourself.
