Bell XH-15
Introduction The '''Bell XH-15''' ('''Bell Model 54''') was an American two-seat utility helicopter designed and built by Bell Helicopter, to meet a requirement for a liaison and utility helicopter for the United States Army and United States Air Force.
Development The Model 54 was a conventional pod-and-boom four-seat helicopter with wheeled, fixed tricycle landing gear, powered by a single 275 hp Continental XO-470-5 piston engine located in the rear cabin, driving a single two-bladed rotor. The United States Army Air Forces (USAAF) ordered three in February 1946 as the '''XR-15'''. The first flight was made in March 1948 with the new designation '''XH-15''', but no orders were forthcoming following evaluation by the United States Air Force (USAF) and the project ended in 1950.
