Re: JH-7/JH-7A Thread
I guess he probably read from Wikipedia. My understanding is that China bought 96 Spey Engine enough for 2 regiment than latter they bought another 48 surplus British Air Force for another regiment Then the production switched over to JH-7A. The rumor then is British help China set up the production for Turbofan engine based on Spey But even that is latter denied by the Designer of JH 7 mr Chen Yijian in interview

At one time China was thinking of exporting JH-7 So the spec that he quoted is probably based on old JH-7
Reports on China’s intention to cooperate with aircraft engine makers in the UK and France to improve the performance of the turbofan of PLA fighter bomber JH-7, are denied by Chief Designer of JH-7, Chen Yijian, Academician of Chinese Academy of Engineering. According to Chen, China has also already fixed problems with the JH-7 turbofan, Hong Kong newspaper Ta Kung Pao reported.
Also known as the Flying Leopard, JH-7 initially used the WS-9 Qinling turbofan, which were from turbofans produced by the Rolls-Royce Spey company in the UK. But after years of research, China has fixed problems with the turbofans of Flying Leopard on its own, according to Chen.
Chen went on to say that China’s research on turbofans is still lagging behind compared with some other countries, especially the turbofans of large aircrafts. China has been calling for more research talents to help solve this problem. He said the third generation of China’s fighter bombers, including the J-8 series, J-10 series and the Flying Leopard, have taken shape of a combatant power, and will appear in the Military Parade to celebrate the 60th anniversary of the nation.
According to Ta Kung Pao, China began research on the WS-15 Qinling-2 Turbofan in 1998. The Qinling-2 Turbofan is an improvement on the WS-9 turbofan, with increased pre-heating temperatures on the turbines and reduced weight for greater efficiency. Tests on the Qinling-2 Turbofan in October 2008 were successful. It is now technically competitive to the late M53-P2 engine from France.
Here is the Spec for M53_P2
M53-P2 - powered later Mirage 2000C models and used to upgrade earlier models [2]
Dry thrust: 64.7 kN (6,600 kgp / 14,500 lbf)
Afterburning thrust: 95.1 kN (9,700 kgp / 21,400 lbf)
Where did you hear that it's still not 100% indigenous? They had a great deal of problems with producing the engine in the '80s, I think it's been resolved by now. I believe the WS-15 is the engine being developed to replace the WS-9.
