Nope. J-36/J-XX both platforms will share same propulsion.. it will be nightmare to produce and maintain two different high end cycle Engine platforms.

i didn't even know that CAS is too working on next gen propulsion up until now. seems like this is for research purpose or for some other application.

apart from this, AECC Shenyang confirmed has ACE/VCE program. most likely is in advance stages right now.

there is one more next gen propulsion program. but very less information is available.
Well, if CAS goes through with this programme to its completion, does it mean China is going to have the world's first 6th generation export fighter? We all know what happens to all the runner ups for PLA projects.

CAS's project isn't focused on conventional VCE, based on their comparison with J58 they are trying to make an efficient engine for high supersonic speeds. Completely different purpose compared to 6th gen engine.

No. Two problems with that train of thought:
1. Why do we think this specific program will reach completion to begin with? For all we know this specific project is tech demo only.
2. Even if it is completed, as has been written by multiple people, this engine is not necessarily suited for fighter applications.

There is such an abundance of funding, resources and talent poured into military aviation, space and hypersonic aircraft + missile programs.

If the same were afforded to civil aviation engines, we'd have Chinese competition to PW, GE, RR and CFM within 15 years or 1-2 product cycles. CJ-1000 may have caught up to the leading edge of 2010s but the state of Chinese military engines have met and in some areas surpassed the West esp scramjets, combined cycles and other continuous detonation engines.

PLA's VCE/ACE programs would be far superior and their programs ahead in basically every way compared to this academic research project. J-36 and J-50 may even get their intended VCE engines when the fighters are ready.

I'm not sure if those engine types (or this VCE demonstrator itself) should be viewed in context of fighter aircraft (whether it's future generations or otherwise).

Applicability to say, reconnaissance aircraft, or future high speed strike bombers may be more relevant in the near term.
Yes, which makes me think those concepts aren't necessarily related to a next (7th) generation "fighter".

I suppose what I'm saying is these engine developments should be interpreted in the whole breadth of possible uses, and people shouldn't think of a next generation fighter in the first instance yet.


Not least because we don't know what 7th generation will look like (we don't even fully know what 6th generation will look like)

Yes, hence the usage of the "platform" term instead of "fighter" in my posts.

However, I certainly do see a lot of merit for a platform that is capable of lobbing AAMs against enemy aerial assets at high-supersonic or hypersonic speeds and at altitudes of 20-40 kilometers (~66000-131000 feet). The advantages from the significant increase in effective interception ranges should be pretty evident from this compared to contemporary AAM launch methods.

In fact, I would see such platforms as further progressions of the J-36, mainly in terms of the capabilities and roles of which the latter is expected to take based on current inferences.

Survivability vs. Prosperity. Perhaps China is still trying to drive the civilian jet engine projects by market forces as much as possible.

I think including a generation number that directly follows 5th and 6th somewhat undermines that effort.

Maybe "future combat platform" would be better, but I am also hesitant to attribute an air to air role to whatever platform or aircraft this engine (or a derivative thereof) could be applied for.


Putting it another way, I think it should be an active goal to undermine the idea that this engine is intended for some sort of combat aircraft that could succeed J-36/J-XDS.

I really think it's better to avoid verbalizing ideas so specifically at this stage.

Not because the idea is implausible, but rather because there is so much which is so plausible for applications of this aircraft and and there are so many ways for what next generation air to air combat can look like, being more generic is probably safer.

Variable-cycle engine for China's next-generation fighter program?

The above photo is of a 7-page article published by the journal "Technology Reward" (科技奖励) in November of 2018 that contains an interview with Mr. Liu Yongquan (刘永泉), who is the chief designer at Shenyang Engine Design Institute. Unfortunately, I do not have access to the article. However, from

Please help with the translation, as I'm not sure about how to translate the green part of the text.
Regarding the VCE program from AECC Shenyang, public reports from 2018 already mentioned it.

Of course, we don't know whether this was an entirely new project or just tested on the WS-10 platform. In any case, the progress of AECC's VCE will be significantly faster than that of CAS.

not true at all. policy has completely changed.

read this post. how much funding AECC Shanghai secured this year. commercial Turbofan is at highest priority right now.

a list of known High bypass Turbofan Engine projects..

1. WS-20 entered in the full scale production.

2. WS-XX a 25 tons class High bypass Engine is in final stages.

3. WS-35 announced in April this year.. most likely a 25-35 tons category class machine for military applications..
----------------------------------------------------------------------------------------------------------------------------
maybe you don't read what we post on Engine thread.. there is an urgency to become fully self-reliance in civilian aviation Engines.

this is why AECC Shanghai received largest ever strategic funding from China's top 12 heavyweight in June this year. it it said to be the biggest ever investment in Aero Engine in last two decades. i just erased the name investment groups but posted the screen-shot.

1. CJ-1000A has entered in final stage. testing phase with C919. then certification for small scale production.

2. CJ-2000 passed demonstrator stage in 2023 now become CJ-2000A and already have couple of prototypes. full scale testing underway. CMC is just one small thing. this Engine have many surprises. highest number of components/parts have made with 3D printed and composite. AECC explicitly said many times, CJ-2000 will be one of the most fuel efficient Engine globally.

AECC official website has updated.. this is the front page of their website.

France is not even in competition right now..

Speaking of France; it's sort of funny how the Chinese aero-engine industry is basically running circles around most of Europe given how the GCAP was stated to likely NOT include a ACE/VCE at all whereas we know that Chinese ACE designs are being worked on that will specifically power their next gen aircraft. France itself doesn't even have anything deployed that's comparable to the WS-19 or the WS-15 currently.
