ABSTRACT:
An aircraft having vertical take-off and landing capability including a nozzle-shaped fuselage housing a power-generating mechanism, a propulsion-developing mechanism at the rear end, and laterally-extending wings located forwardly of the rear end. Each wing includes an aerodynamically composite airfoil having a lower surface possessing a camber curvature. A propeller is provided at the free end of each wing for rotation in a plane parallel to the plane of the wing. The lower surface of each wing includes a thrust flap which may be moved between a first position in which the flap coincides with the camber curvature of the wing lower surface and the propeller provides primarily lift, and a second position in which the flap projects below the camber curvature of the wing lower surface to cooperate with the propeller to compress the flow of air therebetween thereby generating thrust useful for propelling the aircraft in a forward direction.
