From Wikipedia, the free encyclopedia.
The Convair Model 37 was a large passenger aircraft planned, but never built, by Convair. It was to be a civilian airliner version of the Convair XC-99 transport plane, and thus eventually derived from the giant B-36 bomber.
The Model 37 was to be of similar proportions to the XC-99; 182 ft 6" in length, 230 ft wingspan, and a high-capacity, double-deck fuselage. The projected passenger load was to be 204, and the effective range 4,200 miles.
Fifteen aircraft were ordered by Pan Am for transatlantic service.
Unfortunately for the project, the fuel and oil consumption of the six 3,500 hp Pratt & Whitney Wasp Major radials powering the XC-99 and B-36 made the design uneconomic, and hoped-for turboprop powerplants did not materialise fast enough. Fifteen orders were not sufficient for production, and the project was abandoned.
