Bell 201/ XH-13F


One Bell Model 47G was fitted experimentally with a Turbomeca Artouste turbine built under license by Continental as the Model 200-T51T-3; it delivered 425shp. As the XH-13F, it was built at the beginning of 1955 to test some components for the Bell 204.

Bell's first turbine helicopter, the XH-13F, first flew on October 20, 1954, with test pilot Bill Quinlan at the controls. Project engineer for this joint Army/USAF research program was J. R. "Bob" Duppstadt.

The engine weighed so little that it had to be mounted behind the helicopter's fuel tanks and rotor mast for weight-and-balance reasons.

Pleased with the prototype during its Phase I (factory) testing, Quinlan called the XH-13F the "smoothest Model 47 ever built". At the start of April 1955, the prototype was handed over to USAF Major Jones P. Seigler and First Lieutenant Donald A. Wooley. The two officers, attached to Edwards Air Force Base in California, conducted the Phase II test program at Fort Worth to ensure good coordination with Bell.
