I heard the story was FC-31 project was almost canned, but was saved by the dramatic success of WS-19 engine which convinced whoever is in charge to continue to fund the project towards 3.0 with this new engine.

I read that the WS-19 will power JF-17 as well, is that true?

So China will have 2 class of new engines:
WS-15 - top of the line engine for J20
WS-19 - slightly weaker engine for FC-31 and JF-17

Will any other fighters use these engines? Like J10, J16 etc

I'd assume future J-10s and J-16s would use the latest WS-10s, although updating their design and fitting them with WS-15s does not sound outlandish either.

WS-15 : 170 to 180 kN
WS-10 (latest variant) : 140 to 150 kN
WS-19 : 100 to 110 kN (possibly 120 kN)

Any chance of a single WS-15 engine J35? Will dual WS-19 give supercruise?
I don't see a single WS-15 J-35 happening. I would prefer that carrier fighters enjoy the benefit of the safety redundancy of having two engines.

I can see a separate project, a speculative but logical stealthier successor to the JF-17 being powered by the WS-15 or WS-19. But that's another story.

Plus, if anyone has the F-35 in their minds... we all know the only/main reason it has 1 engine is because of the VTOL B variant and the folly of trying to build 3 (really just 2) stealth planes in 1 (or whatever the % parts commonality is).

I think the USN would have preferred to also enjoy that benefit, if they had it their way.

So the J-35 program is jointly funded by both the PLA-AF and PLA-N?
  • (3)以前缺钱,东拼西凑只造了陆基型,陆基型的完善和优化,舰载型设计也做同步调整,保证两者最大限度的标准和结构件通用率!
  • 官媒也报道了,鹘鹰舰载型也在制造中了,(1)只用两年多点的时间,要从图纸变成实机,一架试飞,一架做静力测试,还是挺紧张的!
  • 钱给了,(2) 编号也都给了两年了,按时间推算,官媒称2021年首飞,并非是空穴来风,实机出现时看刷什么编号啦?3501?35001?
Doesn't sound like so.
(3)There was no PLA funding when they made and tested the land-based variant. (2)The type number was given just two years ago, together with the funding. (1)The naval variant was built in two years. These points seem to imply that only naval variant was chosen by PLAN and received funding. Whatever was done before (2020-2=2018) by SAC is from their own wallet and PLAAF was and still not paying.

The only interesting bit is the red underlined part. It mentions full static test for a certain unnamed project. Could be J-XY.
