Powerplant

The initial low-rate production J-10s are powered by the 27,500lb-thrust (120kN) Russian Lyulka-Saturn AL-31F turbofan rated at 17,857 lb (79.43 kN) dry and 27,557 lb st (122.58 kN) with afterburning. The same powerplant is also being used by Chinese air force's Su-27s and Su-30s. Lyulka-Saturn reportedly delivered 54 AL-31F turbofan engines to China between 2002 and 2004. These are the AL-31FN model with special modifications to be fitted in the J-10.

China is also developing its own WS-10A turbofan powerplant, and it could be fitted on the later versions of the J-10. An all-aspect vectored-thrust version of the AL-31F was revealed for the first time at Zhuhai Air Show 1998, leading to speculation that this advanced engine may wind up on the J-10, potentially conferring phenomenal manoeuvrability.
