Chinese Engine Development

This China Central TV reveals a few things:

1 FWS10 has been redesigned, shrinked in the outer dimensions as FWS10A to be used in SU27/J11.

2 The biggest technical challenge was choke stalling in 2004, has been redesigned and passes the design certification in 2005.

3 Some J10s have been fitted with FWS10A.

Let me understand this, so the WS-10 is in mass production for the J-11 series
BUT
the WS-10a is a redesigned version that is going to be used in BOTH the J-11/J-10 aircraft? That doesn't make much sense. I thought the WS-10a had a redesigned gearbox for use ONLY on the J-10

Is there such a thing as the WS-10H for the J-15? If so, which engine is it based on...the WS-10 or WS-10a?

Unless there's an error, the translations given by Sydneylaide seem to indicate that both the aircraft types use the same designation FWS-10A for their engines.

My premise was that adding the suffix "A" should indicate a more substantial change than just a change in the gearbox position, something that's external to the engine core design. Anyway, I think it's a matter of designation only. There's no reason why both the aircrafts shouldn't be using the redesigned and improved version.

Honestly I'm confused too, as I thought WS10 is the designation for the prototype as in J10's case, and it's the mass-production version (no doubt with adjustments to fit J10/11) gets the WS10A designation from the manufacturer & FWS10 from the state.

Anyone?

Actually the original version of FWS-10 is 10A(130kN thrust class, featuring its gearbox and most accessories mounted beneath),designed to power J-10.
in 1987,the "No.10 engine project" was offcially launched ,it included 10A and some derivatives.
