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,[1] which would be able to achieve supercruise.

Design and development

Development of the WS-15 began in the 1990s.[1] The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.[2] 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.[3]
