Gee Bee Model R
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.〔http://www.airfields-freeman.com/MA/Airfields_MA_W.htm#springfield〕 ''Gee Bee'' stands for Granville Brothers.
==Design and development==
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〔Haffke 1989, p. 99.〕 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(), 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. In addition, when steeply banked in such a "pylon turn", it turned out that the fuselage acted as an airfoil, like the 'lifting-body' designs of the 1960s. This allowed the aircraft to make tight "knife-edge" turns without losing altitude. It was, in effect, a Pratt & Whitney R-1340 engine with wings and a tail on it.
