DAYTON, Ohio -- Bentley B.R.2 on display in the Research & Development Gallery at the National Museum of the United States Air Force. (U.S. Air Force photo)
The B.R.2 was a British designed and built air-cooled rotary engine of 230 hp, which was developed late in World War I. The British Sopwith 7F-1 Snipe was especially designed to use the B.R.2, although only three front-line squadrons had been equipped with the Snipe by the end of the war.
The B.R.2 was also installed in the Sopwith TF-2 Salamander, a fighter designed for trench strafing; however, the war ended before the plane could get into action.
