Abstract:

The autogyro is being investigated for potential use as a small unmanned air vehicle for Navy electronic warfare missions. This paper presents wind tunnel test results for a 42 inch diameter unpowered rotor with coupling between feathering and flapping that allows for self-starting from a vertical descent. Aerodynamic performance is given for several blade pitch angles and angles of attack. Autogyro, Rotor, Rotary-wing
