Some (alleged) information on WS-15:
WS-15 is expected to have a maximum thrust of 18.5 tons, which allows J-20B to supercruise at Mach 1.8 and a maximum speed of above Mach 2.2. Besides, WS-15 may have adopted advanced dual-redundancy full-authority digital electronic control system, advanced fault isolation capability and 3D vector nozzle.

The article also suggested the possibility of WS-20 being fielded on the future H-20 strategic bomber.

he is very close friend of mine. XD

its not about reliability. these information are pretty much accurate.

total thrust of WS-15 will be 38,000-40,000 lbf

dry thrust 25,000 lbf

dvanced dual-redundancy full-authority digital electronic control system, advanced fault isolation capability.

the only information in this chart about WS-20 can be the power plant of H-20 bomber. which is not true. H-20 will have low bypass ratio engines.

This way of describing is obviously not an official tone, it may be the selection of some non-professional media.

Dry thrust similar to F119?

All the planes flying with Russian engines still need spare parts though ?
The whole thing is just theoretical anyway "IF Russian can't service..", until we see any proof of this there is no point speculating.

China could make spare parts for the AL-31 series. They know the thing inside out. There are design alterations done to J-20’s AL-31 for the initial batch that wouldn’t have been possible if they didn’t.

Could you expand on this for those of us with little background who nonetheless with to place these developments in the appropriate context? That is to say, what engine or technology parallels lead to your statement that recent developments mean that China is now closing the gap by 20 years (and still has a 20-year gap left to close)?

WS-15 is pretty much counterpart to F-119, which was in a ready state two decades ago. China must close the gap with the variable cycle engine (ADVENT) which is progressing very smoothly and revolutionize turbofan design.

While everyone is celebrating I’d like to sober everyone up by reminding that the WS-15 development took so long that all of the Chinese military forums are now dead and can’t celebrate the news.

I felt like it should have came out 4 years ago. COVID definitely didn't help it. I know they were trying to improve the specs since performance gains with the WS-10 made the earlier specs redundant but better late than never.

Speaking of this, today I was surprised to find that haohanfw

Thank god my account still works.
Hope this is a good sign to loosen controls on military forums
