Earlier helicopters such as the Sikorsky R-4 and the Bell 47 had used piston engines. By the early 1950s turbine engines were being used in fixed wing aircraft and a turbine engine that could turn it's trust into shaft power had been developed, called the turboshaft engine.A major advantage to using a turboshaft engine in a helicopter is that they have a higher power to weight ratio, provide more power for the equivalent size and require less maintenence. the first bell helicopter to use a turboshaft engine was a modifyed version if the Bell 47, designated the XH-13F and first flown in October 1954. The in 1955 with United States Army needed a MEDEVAC helicopter to replace the Bell H-13 Sioux that had been used in the Korean war, and as a result the United States Army awarded Bell a contract to develop a turboshaft powered MEDEVAC helicopter, designated the XH-40. The first prototype of the XH-40 was flown by Floyd Carlson at Fort Worth on 22 October 1956. Two more prototypes were made the year after, and 18 YH-40 test aircraft were made in 1958. The Bell UH-1 soon entered service under the designation HU-1A, which is where it gets it's unique nickname, "Huey".
