The Gee Bee Model R Super Sportster was a special purpose racing aircraft made by Granville Brothers Aircraft of Springfield, Massachusetts at the now-abandoned Springfield Airport (Massachusetts).Gee Bee stands for Granville Brothers.
The 1932 R-1 and its sister plane, the R-2, were the successors of the previous year's Thompson Trophy-winning Model Z.
Assistant Chief Engineer Howell "Pete" Miller and Zantford "Granny" Granville spent three days of wind tunnel testing at NYU with aeronautical engineering professor Alexander Klemin. The aircraft had a very peculiar design. Granville reasoned that a teardrop-shaped fuselage — especially as seen from directly above — would have lower drag than a straight-tapered one, so the fuselage was wider than the engine at its widest point (at the wing attachment point[s], within the length of the wing chord). The cockpit was located very far aft, just in front of the vertical stabilizer, in order to give the racing pilot better vision while making crowded pylon turns.
The R-1 won the 1932 Thompson Trophy race, piloted by Jimmy Doolittle. He also set a new world landplane speed record of 476 km/h (296 mph) in the Shell Speed Dash. The distinction of a landplane record was noteworthy because, at that time, specialized speed seaplanes outran landplanes (e.g. the Macchi M.C.72 with over 700 km/h). The Springfield Union of September 6, 1932 quoted Doolittle as saying, "She is the sweetest ship I've ever flown. She is perfect in every respect and the motor is just as good as it was a week ago. It never missed a beat and has lots of stuff in it yet. I think this proves that the Granville brothers up in Springfield build the very best speed ships in America today."
