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, used to power China's Chengdu J-20 fighter, which would be able to achieve supercruise.
Design and development
Development of the WS-15 began in the 1990s. The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012. 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.
