  • 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

  • AFRL Pulsed Detonation Engine

    AFRL (Air Force Research Laboratory) personnel developed this Pulsed Detonation Engine (PDE) in the 2000s using mostly inexpensive, off-the-shelf automotive components. The engine worked by detonating the fuel-air mixture in repeated, controlled explosions. The resulting shockwaves created a peak

  • Republic YRF-84F FICON

    Please note: This aircraft is in storage.The museum’s YRF-84F participated in two U.S. Air Force experimental programs, the development of the F-84F fighter-bomber and later testing of the “parasite” fighter concept.The museum’s YRF-84F was the prototype of the F-84F Thunderstreak, which became a

  • Boeing YQM-94A Compass Cope B

    The YQM-94A was a high altitude, long-range, Remotely Piloted Aircraft (RPA) tested in the 1970s. It was designed for long-endurance photographic reconnaissance and electronic surveillance missions.Piloted from the ground, the YQM-94A received guidance signals through a radio link. A television and

  • Northrop-McDonnell Douglas YF-23A Black Widow II

    The YF-23A competed in the late 1980s/early 1990s against the YF-22A in the Advanced Tactical Fighter (ATF) program.During the late 1970s, a new generation of Soviet fighters and Surface-to-Air Missiles (SAMs) prompted the US Air Force to find a replacement for the F-15 Eagle air superiority
