The 225-hp R-790 was a standard U.S. Air Corps radial engine used in several types of airplanes during the 1920s and 1930s. Some significant long-distance flights during that era featured R-790s.
The engine on display at the museum is one of three Wright R-790s that powered to Fokker trimotor Bird of Paradise during its non-stop flight from the United States to Hawaii in 1927. The civilian version of the R-790, the Wright J-5 Whirlwind, powered Mr. Charles A. Lindbergh's Spirit of St. Louis during his historic 1927 New York-to-Paris flight.
