Pitcairn PCA2
This is early example of rotary wing technology. It is powered by a 330 hp Wright J6 engine with a ground adjustable propeller. It has a maximum gross weight of 3000 pounds and an empty weight of 2250 pounds. It could cruise at 110 mph with a 50 gallon fuel capacity.
An autogiro has an unpowered rotor that provides lift like the wing of a conventional airplane. The rotor is powered only by the forward speed of the autogiro in flight and must be "spun up" on the ground by taxiing or a take-off roll like an airplane. This particular model has a power take off on the engine to pre-spin the rotor prior to take-off, but must be disengaged before flight. Roll, Pitch and Yaw control is provided by the same control surfaces that you would find on an airplane. Later models had a directly controllable rotor and did away with the wing. They even had collective pitch control enabling "Jump" take-offs. However they lacked the zero airspeed yaw control of a helicopter's tail rotor, so the rotor could not be powered in flight, separating them from a helicopter.
"Miss Champion" was donated to the EAA museum in the fall of 2005. I was part of the crew that assembled it upon its arrival in Oshkosh, in preparation for Steve flying it for a photoshoot and moving in to her new home in the Pitcairn Hangar at the Oshkosh's Pioneer Airport.
