1) J-XDS will not be on WS-10s,
Never said that. It might though. My point is, it doesn't matter what engine it uses – a whole new ecosystem would still be introduced.
Both the J-15 and J-15T have been seen with WS-10s.
One prototype each as far as we're concerned.
That shows me they had every intention of putting the WS-10 on the J-15 family.
And now Yankee and Shilao said "maybe not." I'm not taking their words as gospel, but have you got better sources?
Mixing engines on the same air wing is most likely what the PLAN wants to avoid in the Yankee/Shilao scenario.
The J-35 is coming anyway and that's already introducing a whole another radically different ecosystem. Why not just train the 003 crew for WS-10 J-15T/Ds from the get-go?
PLAN will use domestic engines in future aircraft like the J-35 and the J-XDS.
Exactly. So why are they not getting this over with instead of relying on another country?
But the J-15 and WS-10 families might not be guaranteed for the second Type 003, 004 or 005 so re-engining them might be moot.
It all depends on whether they will need to build enough new J-15Ts to outfit air wings without mixing in older batches of J-15 variants and creating support for two engine types.
So, an F-14D situation. Exactly what I was questioning why the PLANAF isn't avoiding.
Is WS-10H spooling issue resolved.
Yes. It has never been a problem in any variant since the introduction of the contra-rotating spools. The performance/production rate of the WS-10 isn't the limiting factor here and that was mentioned in the video.
Is overall performance and TWR similar to latest AL-31F engine.
Yes. Every WS-10 variant from 10A on are superior to their Russian contemporaries.
Until and unless used frequently and in large quantities in seaborne conditions, one cannot come to certain conclusion what issues it may face while operating in seaborne condition.
This isn't an excuse. Are they just never going to use WS-10Hs because "they don't know how they'll really fare"? What in the positive feedback loop? You'll have to start somewhere.
4) If incase Russia is unable to provide engine due to certain war or any other issue who would be carrying out the mass testing of WS-10H engine. Whatever logistical issues which we are facing right now could turn out to be very big deal if war breaks out which involves China's interest. Should never be depended on foreign supplier (even if it's a close ally) when the alternative is readily available.
5) Indigenization of local parts and assembly is must and you can't be depended on foreign supplier and that to heart of the fighter plane.
That is exactly the concern that I'm stressing. But given how the WS-10H is already a viable option, I'm inclined to believe that the mass testing is already done.
