The WS-15 (Chinese: 涡扇-15; pinyin: Wōshàn-15), codename Emei, is a Chinese afterburning turbofan engine designed by the Shenyang Aeroengine Research Institute and manufactured by the Xi'an Aero-Engine Corporation, which will be used to power the Chengdu J-20, which would be able to achieve supercruise.
Design and development
Development of the WS-15 afterburning turbofan engine began in the early 1990s. In 2005, the engine performed successfully on the testbed. In 2009, it was known that the prototype was able to achieve 160 kilonewtons (36,000 lbf) and a thrust-to-weight ratio of 9. The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.The new engine is speculated to incorporate two-plane thrust vectoring nozzles. As of now, the only in-service, in-production fighter jets using this technology is the Sukhoi Su-35 and Sukhoi Su-30MKI. This feature allows the aircraft to produce thrust vectoring moments about all three rotational axes, pitch, yaw and roll.
