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]
In March 2022, it was reported that the WS-15 engine has been undergoing refitting among earlier LRIP variants of the J-20. The advanced engine will replace Russian-supplied engines in order to enable the J-20 to achieve supermaneuvrability and supercruising capability, thus matching other stealth fighters like the Lockheed Martin F-22 Raptor.
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.[2] The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.[3]
In March 2022, the Chinese state television reported that a new engine, WS-15 has been put through a series of tests. The WS-15 turbofan engine is said to have increased the J-20's maneuverability and combat capability during the test. Moreover, the addition of the WS-15 also enables J-20 to supercruise and provide it with thrust vectoring control capability and enhanced supermaneuvrability, as per reports by state-run Global Times.[4] The report by the state television did not say when the engine would be ready for assembly, but according to the military source that process has already begun with early J-20 fitted with Russian-supplied engines being replaced with the advanced WS-15. Additionally, it was reported that J-20 variants fitted with WS-10C, another thrust vectoring engine, wouldn't be refitted with the WS-15 engine.[5]
