Being equipped J-20, WS 15 engine actually has eliminated the gap with the U.S. and European engine

According to the Russian military Equality Network on May 31 reported that, although the Russian military had stopped the development work of the world's first supersonic V / STOL fighter aircraft - Jacques -141, but the R-79 -300 engine which developed for the aircraft has not been abandoned. Recently reported that in 1996 China had already received the technical information of this type of engine and an engine products.

Russian media said that there were reports that Russia plunged into serious economic difficulties in 1992 forced to give up Jacques -141 vertical / short-range fighter development program decisions. Russian authorities are at a air show in Belarus announced the decision. R-79-300 engine from Russia "coalition" aircraft engines synthesis of science and technology development Co., Ltd., in the Lok Ma Jacques -141 program, its not yet been adopted by other models. In order to obtain the necessary funds, Russia in August 1996 provided China signed a document of this type of engine. China thus won the R-79-300 engine complete set of drawings and technical documents, and a non-vectored thrust nozzle of the engine. However, in 1998, due to the impact of the Asian financial crisis was plunged into economic difficulties, Russia finally agreed to provide China with R-79-300V vector control engine nozzles and related production technology.


Russian media said, according to Russia's technical documents, the Chinese Academy of a gas turbine in the R-79-300 engine on the basis of successful development of the domestic WS-15 series engines. At present, the engine has been derived from a variety of modifications, of which the "WS-15X" for China's fifth generation of heavy equipment, multi-role fighter J-20.

In addition to excellent aerodynamic design, J-10 fighter's high mobility also stems from the powerful AL-31 engine 

Russian media said that China-made parts of WS-15 engine parameters: maximum thrust of 161.86 kN (on afterburner, not open when afterburner 105.22 kN), bypass ratio is 0.382, the pressure coefficient of 28.71, before the turbine temperature of 1447K, the maximum diameter of 1.02 meters, 5.05 meters long, with a total weight of 1862 kg. WS-15 engine is also equipped with advanced full-authority digital electronic control (FADEC). Experts believe that, by virtue of the WS-15 project's success, China is narrowing the development of modern Europe, America and the Russian military jet engine in the field of the gap.


Jacques -141 former Soviet Union was developed to replace Jacques -38 a short distance / vertical landing aircraft, originally planned for the equipment, "Kiev" class aircraft carrier. The aircraft were equipped with three engines, which are a type of R-79-300 turbofan engine thrust vector (in the body back) and two in the rear cockpit was installed in the RD-41 series-type lift engines.
