Major applications Chengdu J-20
Status Under development

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.[1]

The WS-15 is intended to power and enable supercruising on the Chengdu J-20.[2]

Design and development[]

Development of the WS-15 afterburning turbofan engine began in the early 1990s.[1] In 2005, the engine performed successfully on the testbed. An image of the core appeared at the 2006 China International Aviation & Aerospace Exhibition. In 2009, a prototype achieved 160 kilonewtons (36,000 lbf) and a thrust-to-weight ratio of 9.[3] The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.[4]
