Russian tech firm launches work on sixth-generation engine for combat aircraft​


At the moment, Russia is developing fifth-generation engines, which are item 30 for the Su-57 fifth-generation fighter and the Item RF for the prospective aviation complex for long-range aviation

MOSCOW, July 16. /TASS/. Russia’s United Engine Corporation (part of the state tech corporation Rostec) is launching R&D work on the sixth-generation engine for combat aircraft, United Engine Corporation Deputy CEO for Strategy Mikhail Remizov told TASS on Friday.

"Now work is starting in several promising areas: the technologies of the sixth-generation engine, a combined powerplant, and the more electric engine technology. The R&D effort on the sixth-generation demonstrator engine technology has been included in the long-term work schedule of the United Engine Corporation and our applications for state program financing," he said.

A government decision and state financing will be required for the work on developing the sixth-generation engine, the deputy chief executive said.

Russia is currently developing fifth-generation engines: Item 30 for the Su-57 fifth-generation fighter and the Item RF for the prospective aviation complex for long-range aviation (PAK DA).

Problem is: that's not main line and never supposed to be. They are in process of making a new one in different building along with hiring hefty numbers of new personnel (said to be 500+). Thus expected speed growth in upcoming years.

That could be the prodline, only we don't see the whole line.. only the first/last 3 airframes;)

You are looking at mostly the Su-35 line. Which of course a serial mass produced plane, but probably quite a bit simpler than the 57 line.

Whoops, I completely missed the explanation in French above the pic. D'oh.

OTOH, in which case I'm even more appalled! That's incredibly austere for a long established production line.

Russia's Su-57 Heavy Fighter Bomber: Is It Really a Fifth-Generation Aircraft?

Russia's Su-57 aircraft has been in development since 2002 and is considered a key part of Russia's arms export industry as a fifth-generation fighter. Despite continued Russian efforts to sell the aircraft, it is unlikely that a fully developed and full production–ready Su-57 will be available...

I'd advise ignoring the title, that's only referring to the very last paragraph, the rest of this has some interesting thoughts on the Su-57's export potential - OTOH it is from RAND, so certain biases can be assumed.

RAND biased!?! Surely you jest Sir! Why they are the most circumspect of experts. Just ask the USAF Inc.
 
The question from Rand is actually quite legit, and it would be fair to say that 5.5G is a more accurate classification of the plane. When the "first iteration" NGAD (i.e. F-22 refreshment) comes online we can talk further about the topic

5.5?!!
But is it at least Stealth?
No (most airframe don't have coating)

Sorry I forgot "stealth" is not a technical parameter based on some analog RCS magnitude given in dBsm for a given frequency, polarization and aspect, but a BOOLEAN buzzword as in TRUE (anything US MIC produces) and FALSE (anything that Russia clumsily attempts). I think we saw already in the dedicated thread the depth of the Western claims in this regard, and I also think it is better not go further down that path here.

BTW, some key features of NGAD to be considered: speed, payload, range. Now think about the caveats that apply to the "European version" of it, and let me know if considering those two aspects together does not ring a bell for you.
 
F-22 have only single radar array in X-band, while T-50 have five to eight radar arrays in both X-band and L-band. F-22 have no dedicated active ECM suite and relies only on main radar array for very limited ECM, while T-50 have dedicated ECM suite which utilizes both radar arrays and its own arrays, plus full coverage by DIRCM system. F-22 relies solely on main radar for search and track and have no passive SaT capability, while T-50 have dedicated IRST station plus wide array of IR and UV sensors for 360 degree passive coverage for search and track. F-22 is limited in both AA and AG work, being unable to carry LRAAMs and most of guided air to ground ordnance, which limits its usage as multirole. T-50 has both wider array of AA options, including LRAAMs, and wider array of AG options, including ARMs, CMs and AShMs.

Based on all that, glorified Me states that T-50 is six gen when compared to widely accepted fifth gen of F-22.

Sorry I meant it as a joke from the directed negativity of what gen aircraft it is by comparing their aircrafts to the U.S. to calm them down. Might as well throw a comparison in from what the Su-57 has with the F-22.

1626674793499.png
1626674875901.png
I have heard that for MAWS the F-22 is both infrared and UV. And KRET and RTI stated 10-15 years or 5-10 years somewhere in their articles(don't want to relook depressing information) cant remember which of the 2 have said which, announced they are behind in MMIC technology so I will say 10 years behind in AESA radar technology. Meaning if the F-22 received that 4th gen radar in 2007 the Su-57 if still using MMICs, has better upgraded their radars somewhere in 2017 or afterwards. 2009 is quite old for their existing radars hence I am assuming project megapolis by new avionics they mean new radars for 2022-2024.

The F-22 could have been further upgraded to be like the Su-57 but the F-35 came later or as other users before suggested to me more expensive to implement. If the U.S. did go with the F-22 upgrade plan they might have maybe called it a 5.5 gen. The only thing I don't like is how this aircraft was treated during hurricane season in Florida, they have to respect beauty and dedication more.

I didn't mention the IRST because some say addition to RCS and the others give a minimal RCS exception for a further view. Example: F-22 with IRST is .0005 one without it is .0001 but the IRST capability makes one F-22 see the other F-22 better before that F-22 can spot that one with radar, etc, etc.

Plus even more problematic issues like fixed intakes, small bays, small fuel fraction, no advanced lift augmentation devices, huge fixed tails and thirsty heavy engines. Compared to PAK-FA's stealthy fully adjustable intakes, huge oversizing of airflow, likely 2 stream VCE izd. 30 with 18 t thrust, TWR 13, highest specific thrust, big fuel tanks and huge deep weapon bays, supermaneuverability, all moving keels, LEVCONS... 5.5G is a modest assessment.

If you're going down this path, then the significant issue is not aerodynamics, engines or systems, but systems integration to give full sensor fusion. We know the F-35's sensor fusion supposedly blows pilots away, we've seen very little on where Su-57 stands in comparison.

You can stuff an old airframe with new avionics and upgrade that part (this is routine around mid-life of any platform), but you cannot avoid its fundamental kinematic and physical limitations that way. That is why this fake dichotomy between SA and kinematics is nothing but brainless sales chatter, having SA does not impede you having a good airframe, too, and you can bet your last cent your enemies will do exactly that. The fact that F-22 does not receive a thorough mid-life avionics upgrade as any other fighter before should make you wary that everything is ok with it, airframe wise. Of course the F-22 has significant limitations, and that is the reason why NGAD goes the path it does and that we hear about flying prototypes already. I am not even making things up, this is your own USAF leadership saying so. Airframe wise, the F-22 is surpassed in every aspect by the Su-57. But US side prefers to focus on stealth, which is not possible to assess seriously from the outside unless in very obvious cases, in which PAK-FA does not belong.

Communication and navigation systems for the Su-57 fighter will be presented at MAKS-2021

Also, visitors to the air show will be able to get acquainted with the S-108 communication and data exchange complex from the Su-35 multipurpose super-maneuverable fighter, with an on-board communication complex based on integrated modular avionics technology

MOSCOW, July 19. / TASS /. The Ruselectronics holding of the Rostec state corporation will show at the MAKS-2021 airshow communication, navigation and identification systems for the Russian fifth-generation fighter Su-57. This was reported to journalists in the press service of Ruselectronics.

In particular, NPP Polet (part of Ruselectronics) will demonstrate at MAKS-2021 the S-111 communications system from the Su-57 fifth-generation multipurpose fighter. "The equipment provides telephone radio communication and aircraft data exchange with other aircraft for various purposes, as well as with ground, air and surface control points. The equipment uses the latest high-speed information transfer technology and uses advanced network solutions," the holding said.

In addition, the newest development of NPP "Polet" will be presented - the unified system of communication, data exchange, navigation and identification (OSNOD). "Currently, the OSNOD system terminals are installed on the Su-57, Su-30SM aircraft, the modernized Su-27, Su-34, Su-35S and on the export version of the Su-35, on the Il-76 of various modifications, the Il-112V, and also on modernized long-range aircraft - Tu-95, Tu-160. In addition, ground control points and communication centers are equipped with the OSNOD system, "Ruselectronics said.

Also, visitors to the air show will be able to familiarize themselves with the S-108 communication and data exchange complex from the Su-35 multipurpose super-maneuverable fighter. The complex provides noise-immune closed data and voice information exchange over the air-to-air and air-to-ground lines.

In addition, an onboard communications complex based on integrated modular avionics technology will be demonstrated. Due to the open architecture, modular construction principle and the use of standardized data exchange protocols, the functionality of the complex can be supplemented and modernized without significant costs. In addition, the equipment can be installed on a variety of media.

Wanted to know more their latest communication equipment like the OSNOD which was talked about before but not in too much details on how it was better improved in data exchange.

Click to expand...

If your victory is dependent on your airframe kinematics, you're doing it wrong, because that implies you're seeking out a "fair fight", when that's precisely the thing you should be avoiding. If you aren't cheating you aren't trying hard enough. And sensor fusion is a major step towards getting the information necessary to do that, and to get inside your opponents OODA loop. Hell, Ogarkov's Military Technological Revolution is a Russian idea, not an American one, though the US grabbed it with both hands as the Revolution in Military Affairs.

(The idea of stuffing an old airframe full of new avionics isn't as simple as you seem to think. And that's for any old airframe, a stealth airframe makes it massively more difficult).

F-22 does not receive a thorough mid-life avionics upgrade as any other fighter before should make you wary that everything is ok with it, airframe wise.
Click to expand...

It's pretty clear from the avionics perspective that F-22's avionics architecture is problematical and the issue isn't the airframe (other than their only being 200 of them) but that F-22 doesn't datalink into networked warfare particularly well.

this is your own USAF leadership saying so.

My USAF leadership? I think you're mistaking me for American.

Well its that time of every 2nd year, in which some people goes all out :mad:o_O:p
Some love it, some outright hate it.

Sinse Russia now is a red country in the Covid Pandemic map, it must affect the Air salon pretty badly.
Cudos for them trying to put on a good show!

Thing is that there is no point to bother about the rivets, skin quality and RAM on both: be it an F-22 of USAF demo-team(which is depicted on that photo) or T-50 flight prototype #510.

BTW, not so long time ago someone already posted here the difference in skin and coating between the #510 prototype and #01 production airframe.

Exactly. Eighter people have very short memory, or they never actually read the stuff being posted here, only interesting in running a sh!tshow..

Anyway, the show must go on.
Do you think they get to sign more orders on Su-34 or Su-35S?

Su-34M - highly probably...albeit i'm not a fan of it.
Su-35S - not sure we need it. Would be better to fully focus KnAAZ on Su-57 production increase.
