WS-10/Taihang is ready

[vce]

From what I heard, the J-11Bs are indeed using the WS-10A, but the AL-31s are still used for J-10s. This is because J-11B is a twin engine plane, so if one engine fails, the plane can still survive. Using WS-10A on J-11B is essentially an extensive user test of reliability. If everything goes well for a few more years, J-10 will use WS-10A, too. The AL-31 is being phased out, but not gone.

J-11B is equipped with FWS-10 engines,each rated at ~125kN thrust with afterburner(ISA,SLS,uninstalled). the more powerful derivative--FWS-10A is designed to power J-10 .

To make my point clear, i do not beleive the WS-10 is ready for mass production because no official word has come from the Chinese. Moreover, the Chinese recently ordered more AL-31's. I am not saying the WS-10 is bad, nor am i saying it will never come into full production. I hope this settles it

as the signboard description in the image said: the FWS10 already entered mass production stage
