Wright R-1820 Cyclone Engines (and propeller assemblies), owned by the NMUSAF and determined excess to collection needs. Engines (and propeller assemblies) were removed from the Northrop YC-125B and Lockheed C-60A aircraft located at the National Museum of the USAF, Wright-Patterson AFB OH. Engines (and propeller assemblies) are “as is” “where is” and have not been maintained to airworthiness standards. No maintenance records are available for the engines (and propeller assemblies) and total times are unknown. Engine variants include R-1820-87, -205A, -97, -202A, Lycoming.
The Wright Aeronautical Corp. introduced the 9-cylinder, air-cooled, R-1820 radial engine in 1931. Developed from earlier "Cyclone" engines of the late 1920s, the larger and more powerful R-1820 produced 575 hp; however, engineers dramatically improved its performance over many years of production, with several later versions being rated at 1,525 hp. Although the R-1820 powered thousands of military and civilian aircraft, it remains best known as the engine that powered Boeing's B-17 Flying Fortress in World War II.
