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 afterburning 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] which would be able to achieve supercruise.

Design and development

Development of the WS-15 began in the 1990s.[2] The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.[3] In 2005, the engine performed successfully on the testbed. In 2009, it was known that the prototype was able to achieve 160 kilonewtons (36,000 lbf) and a thrust-to-weight ratio of 9.[4]

It has been speculated that WS-15 is heavily influenced by the Russian R-79V-300 turbofan engine which powers the supersonic VTOL fighter aircraft Yak-141. In the beginning of 1992, China obtained technical drawings of R-79 and technical data from its manufacturer Kobchenko/Soyuz. Later, China obtained thrust vectoring technology of R-79 and even the design plans for the proposed R179-300 engine, a future upgrade of R-79.

Compared to other turbofan engines which powers fourth-generation jet fighters, such as China's indigenous WS-10, WS-15 features various improvement, including increased turbine inlet temperature, more efficient and durable wide-chord fan blades and advanced manufacturing processes to produce integrated engine components.

CJ-1000A

The CJ-1000A is a high-bypass turbofan in development by the same group as the WS-15, and is based on the WS-15 core. CJ-1000A was reported as being targeted for the Comac C919 passenger aircraft and the Xian Y-20 strategic airlifter, with a thrust of 10,000–19,999 kilograms-force (98,070–196,120 N; 22,050–44,090 lbf).[5]
