FJR710 Jet Engine

The jet engine FJR710/600S is the first high-bypass ratio turbo-fan engine in Japan that was born under the project ‘Research and Development of Aircraft Jet Engine’ by the then Agency of Industrial Science and Technology, Ministry of International Trade and Industry in 1971. For the research and development project, the National Aerospace Laboratories of Japan (currently the Japan Aerospace Exploration Agency) handled the element research and operating tests, and IHI Corporation, Mitsubishi Heavy Industries, Ltd. and Kawasaki Heavy Industries, Ltd. took charge of design and trial manufacture. The high-altitude performance testing of the engine was executed at then NGTE in England and the advanced technology was authorized, which led to the international jointly developed engine V2500 currently used in the Air Bus A320, etc. The FJR710 jet engine was also used in the short takeoff and landing aircraft ‘ASKA’ of the National Aerospace Laboratories of Japan and served as a foundation for Japan’s civil aviation engines. Main specifications are as follows: thrust force, 4.8 tons; fuel consumption, 0.39 kg/hr/kg; bypass ratio, 6; overall pressure ratio, 19; and weight, 1,080 kg.
