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 to power the Chengdu J-20,[1] which is planned to achieve supercruise.
Design and development
Development of the WS-15 afterburning turbofan engine began in the early 1990s.[1] .[3] The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.[4]The new engine is speculated to incorporate two-plane thrust vectoring nozzles.
