The WS-15 (Chinese: 涡扇-15; pinyin: Wōshàn-15; literally: "turbofan-15"), codename Emei, is a Chinese afterburning turbofan engine designed by the Shenyang Aeroengine Research Institute and manufactured by Xi'an Aero-Engine Corporation. It is intended to power the Chengdu J-20 fighter,[2] which would be able to achieve supercruise.
Design and development
Development of the WS-15 began in the 1990s.[2] The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.[3] 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.[4]
Compared to other turbofan engines powering fourth-generation jet fighters, including China's own indigenous WS-10, the WS-15 features various improvements, including increased turbine inlet temperature, more efficient and durable wide-chord fan blades, and advanced manufacturing processes to produce integrated engine components.
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.[5]
