WS-15/WS-19 is in same category class Engine means 5th gen according to western standards like J-20 but in Chinese books they count as 4th but i think in this press conference they go with the flow. following standard procedure what we all know..

remember, China's next gen engine will have thrust to weight ratio 15.. this is likely the engine they are talking about as 6th gen Engine.

one more thing, this 2400K TIT is not standard for next gen Engine, this is normal development cycle in Gas turbine industry. if i m correct, both GE/PW have 2400k material but still not yet commercial.

China Engine Material also reached at 2000k and 2400k is in advance phase of development.
Afaik 2200°K is pretty mature and might be close to actual application.

Isn't the turbine inlet temperature speculated to be 1850K for WS-15? Making it "4th gen" as per that slide. The text beside "6th gen" says "fully novel engine design" which could mean just about anything -- if we are to assume 5th gen is ACE/VCE, perhaps 6th gen is RDE which we know they have been working on.

This was the original figure from the late 2000s. Make of that what you will.

Guys, any updates on China's ceramic matrix composites (CMC) turbine blades development? From my understanding they have not tested anything equivalent to the GE F414 CMC.

Thanks, the picture indicates China's CMC engine is at a very early developmental stage, it took GE 10 years from F414 CMC to a working XA100, therefore, it's reasonable to assume a Chinese XA100 equivalent will come out at around 2035.

what's your best estimate for CN's timeline? when will they be able to produce a XA100 equivalent?
Perusing the research output on variable cycle engines all signs suggest they more or less have some candidate engine cycle designs completed. Whether they’ve proceeded to physical prototyping is an open ended question though the data in some of these papers suggest that they at least have some kind of physical test articles. Beyond that it’s hard to say. Chinese engine development is very secretive. For example the WS-15 is already in production and we know almost nothing about it.
