The Firestone Aircraft Company of Akron, Ohio was a subsidiary of the Firestone Tyre and Rubber Company which took over rights to a number of the Pitcairn Autogyro Company designs via an acquisition of G&A Aircraft of Chicago in 1944. G&A Aircraft had previously built six examples of the XO-61 two-seat gyroplane for the U.S. Army. This experience was applied to the design of a new helicopter for the U.S. Army, designated Model 45. The Model 45 was a conventional pod and boom helicopter with tandem seating, a fixed tricycle undercarriage and a three-blade main rotor. The original Model 45B design used a 126hp XO-290-5 engine and the Model 45C (military XR-9A) was a development with a two-blade rotor. However, neither of these was actually built and the prototype (which carried the identity 6001) was designated XR-9B and was fitted with a 135hp Lycoming O-290-5 engine. Firestone also built a civil version, the Model 45D (NX58457), with side-by-side seating but development of helicopters was abandoned by Firestone in 1947. |
