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]
SF-A[]
The SF-A is a high-bypass turbofan in development by the same group as the WS-15, and is based on the WS-15 core. SF-A was reported as being targeted for the Xian Y-20 strategic airlifter and the Comac C919 passenger aircraft, with a thrust of 127 kilonewtons (29,000 lbf), and was projected to enter production in 2016.[4]
