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]

In March 2022, Chinese state media reported that the J-20 had performed trials with the engine and experienced significantly improved performance.[5]
