Chinese Aero Engine information thread

How do you know WS-18 is low by pass? It looks like DKP30 engine, doesnt mean it performs like it. With new metallurgy, WS-18 spec is definitely better than old Russian engine. Plus, PLAAF seems very satisfy for WS-18 that they continue using this engine with very slow induction phase of WS-20.

As it seems, all operational Y-20s so far are using original D-30KP-2 engines

Finally...
J-10B/C/S, J-11B/BS/BH/BSH, J-16/D, J-20, and J-15 have equipped with WS-10 engines.

Indeed ... so eventually - similar to the re-engined J-10AS we've seen a few weeks ago - a hint that SAC is at least testing them.
To be sure it is converting all operational J-15s to WS-10 is IMO too early yet.
