This invention relates to autogyros and to counter-rotating rotor helicopters. It further relates to compound autogyros and/or helicopters that employ a lifting surface or wing in forward flight. More specifically this invention provides an autogyro with counter-rotating rotors, circular planform wing integral with the rotors, and means for engaging power to the rotors for vertical ascent, descent and hovering.

In an autogyro, the combination of: a fusilage body, a rotor pair comprising two rigid circular structures each profiled with a a flat face and a convex airfoil surface, peripheral blade sets on said structures, said structures being disposed with their faces so close together that their convex surfaces form a single aerodynamic wing, means for mounting and gearing said rotor pair for counter-rotation on a common axis, gimbal means securing said mounting means to said body, and means in said body for controlling the tilt of said rotor pair relative to said body.
