Xian WS-15

WS-15
Type	Turbofan
National origin	People's Republic of China
Manufacturer	Xi'an Aero-Engine Corporation
First run	2006^[1]
Major applications	Chengdu J-20

The WS-15 (Chinese: 涡扇-15; pinyin: Wōshàn-15; literally: "turbofan-15"), codename Emei, is a Chinese 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]

Design and development

Development of the WS-15 began in the 1990s.^[2] The thrust target was reported as 180 kilonewtons (40,000 lb_f) in 2012.^[3] In 2009, it was known that the prototype was able to achieve 160 kilonewtons (36,000 lb_f).^[4]

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 lb_f), and was projected to enter production in 2016.^[5]
