Prototype certainly will not have WS-19, but i assume first serial aircraft will have it. China already mastered all crucial engine techs so development will go smoother and faster than previous models.

true. But we also had no clue how it goes with the ws15, are we?

Yes, but since there seems not to be the expected progress for the WS-15, why should there be greater one with an even younger WS-19?

Surely, but don't we expect the same for the WS-15 since years ...

Unless WS-19 is easier and its development cycle benefited from WS-15's and WS-10's. WS-19 is touted as a 5th gen level mid thrust engine in the same "generation" of technology as WS-15, rather than being of the same generation of technologies that gave us WS-10A and early variants of WS-10.

This means WS-19's development time may be less than WS-15 and could even be considerably less who knows. Maybe WS-19 is simply an upgraded WS-13 with new materials and other evolutionary improvements rather than a complete ground up and therefore could take much less time if those evolutionary developments directly came from WS-15 and WS-10 research and development.

That all may be correct, but this all includes so many IFs ... and therefore as I said my hopes are de facto nil to see the J-35 prototype with it flying; and that was the original question.

I think WS-19 spec is more easier to achieve. 25,000lbs thrust is achievable by upgraded version of last gen engines like F414-EPE, EJ2x0 and M88-4.

Oh please, it is maybe easier, but not that easy at all ... since the Chinese don't have any "last gen engines like F414-EPE, EJ2x0 and M88-4". They start from not such an already modern engine

But now let us stick to the topic, this is too much semantics on engines!

Eh. The basic technical challenges between a mid sized engine and a large sized engine, which is the materials, the aerodynamic modeling, the mechanical engineering, etc should be the same. Whatever the tech level is at for large engines should also be the case of mid sized engines.

Agreed, but my reply was aimed against hist argument … anyway it makes it still not likely to see the WS-19 before the WS-15.

Any other big bottle neck is human resource. These cutting-edge engines can't be developed by new grads. These projects needs tons of experienced engineers. Given China's history in aircraft engine development, China probably don't have enough talents to support so many projects in parallel, even if these projects can share some key technologies.

Don't underestimate China's young talents. You should refer the launch of Tianhe core module, autodocking cargoships, autodocking of apcaeships that carry crews of CSS, powerful rocket CZ 5B and others. Don't forget the Rover Yutu on the moon. the Zhurong tover on Mars. All these achievemsnts are carried out by China's young talented scientists, engineers, AI electronics experts and administrators.
