It's about WS-12, nothing to do with FC-31

WS-12 ???

Thanks, but interesting that it gained a new, separate designation.

WS-10B

The FC-31 program is still being developed?

Why not? There is no sign of being orherwise.

Well, unless the PLANAF, PLAAF, or another customer purchases it, is there an incentive to pour money into a stillborn project?

And the number count again? I come to 15! Or am I wrong?

Your count appears correct. What's the significance of 15 petals?

Here's an album with several pictures of the engine:

Clearly 15 petals.

Short, Stubby Nozzles : Check
Neither 16 nor 18 petals: Check

The hints are being dropped again and again

Some individuals think the WS-15 also has 15 petals

Could be that other engines also have nozzles with 15 petals, or that there's just one common TVC nozzle for both WS-10 and 15. Is there any evidence that this is the WS-15?

IMO highly unlikely ...

Yes, but that does not necessarily means THISs nozzle has to be a WS-15, ...

No ... and therefore IMO it is more likely a test-nozzle related to the WS-15's one but here mated onto a WS-10.

It makes no sense at all to test a new and completely unproven engine together with a new nozzle on a single engine type ... and the fact that they show it at Zhuhai is IMO proof that it is 100% for sure not the WS-15.
