  • Williams International F112-WR-100 Turbofan

    This type of small turbofan engine powered the X-36A, a remotely piloted aircraft used in 1996 to demonstrate the tailless agile fighter concept. Because the X-36A was a scaled-down version of a potential fighter design, the small Williams F112 engine was ideal for the project. The F112 also powered

  • Westinghouse J34 Turbojet

    Developed by Westinghouse Electric Corp. in the late 1940s, the J34 engine was an enlarged version of the earlier Westinghouse J30. The J34 produced at least 3,000 pounds of thrust (depending on engine series) and was twice as powerful as its predecessor. Some J34 versions were fitted with an

  • Rolls Royce Avon MK 203 Turbojet

    The Avon MK 203 is an axial-flow turbojet engine similar to the Avon RA.28-49 used to power the vertical takeoff and landing Ryan X-13 Vertijet aircraft. This engine was donated to the museum in July 1986 by Rolls Royce Ltd., Glasgow, Scotland.TECHNICAL NOTES (Avon RA.28):Compressor: 15-stage axial

  • General Electric YJ93-GE-3 Turbojet

    General Electric designed the highly-advanced YJ93 engine to power a planned supersonic interceptor, the F-108, and a bomber, the XB-70, at speeds of 2,000 mph and at altitudes of about 70,000 feet.The high-pressure, variable-stator engine ran on special high-temperature JP-6 fuel and had a

  • General Electric YF120

    General Electric developed the prototype YF120 engine in the 1980s under a demonstration contract for the Advanced Tactical Fighter (ATF). The General Electric YF120 competed against the Pratt & Whitney YF119 engine. The engine on display was one of two YF120 engines installed on the YF-23.To save

  • General Electric T31

    The T31 engine was the first American turboprop engine to power an aircraft. It made its initial flight in the Consolidated Vultee XP-81 in December 1945. The T31 was mounted in the nose and a J33 turbojet engine mounted in the rear fuselage provided added thrust.The T31 was also used on the Navy’s

  • General Electric J35-A-17D

    Originally developed by the General Electric Co. at the end of World War II, the J35 was the USAF's first axial-flow turbojet engine. In 1947 GE transferred responsibility for the production of the engine to the Allison Division of General Motors.The J35 engine powered two important USAF fighters,

  • General Electric J31

    Note: This engine is on display in the National Aviation Hall of Fame.The J31 (General Electric designation I-16) was the first turbojet engine produced in quantity in the United States. It was developed from the original American-built jet engine, the General Electric I-A (which was a copy of the

  • Allison V-3420

    The V-3420 is a 24-cylinder double-vee, twin-crankshaft, liquid-cooled engine derived from the V-1710, a 12-cylinder engine that powered such World War II aircraft as the Lockheed P-38, Bell P-39 and the Curtiss P-40.Essentially, the V-3420 is two V-1710 engines mounted on a single crankcase with

  • Allison T40

    The unusual Allison T40 turboprop engine combined two T38 gas turbine power sections that drove a common gearbox (turboprop engines typically have only one gas turbine power section). A unique version, the XT40-A-1, powered the experimental XF-84H aircraft. While most T40 engines drove
