today when i open a military news&pics website of china,i found these photos below. these pics should interest those people who knows something about chinese fighters and engine industry. suppose the pic is real.(seems not fake one.) u would suddenly know the point is that the engines r WS-10(or å¤ªè¡Œ Tai Hang). and now,we have seen WS-10 has been tested on J10B,J15(chinese verion Su33),J-11. J15 J10B No.5 another J11 with ws-10 pic so.seems WS-10 would take an important place in PLAF. oh,if WS-10 can be used by J10B,which is a single engine fighter,does it mean that WS-10 will take place of AL-31f in PLAF?
