The Bell XH-15 (Bell Model 54) was an American four-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[edit | edit source]
The Model 54 was a conventional pod-and-boom four-seat helicopter with a wheeled, fixed tricycle landing gear and was 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. 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.
Variants[edit | edit source]
- Military designation for three Model 54s ordered for evaluation.
