ABSTRACT:
An aircraft is provided with a wing in the form of an annulus having an airfoil shape in radial section, the wing being concentrically mounted on a vertical axle shaft which in turn is rotatably carried by a mounting on the fuselage. Rotation of the wing drives air centrifugally across the upper and lower surfaces to energize the boundary layer, enhance laminar flow, and produce lift. Vanes may be mounted on the inner portion of the surface to increase the flow and thus produce greater life. The vanes may be attached to a stabilizer ring which is eccentrically adjustable by a controlling mechanism to vary the extension of the vanes into and out of the wing at various points in the cource of rotation and thus vary the degree of lift produced. The wing may also be provided within its inner perimeter with airfoil lifting blades which produce additional lift, and the blades may be swung by a stabilizer ring to positions producing a desired thrust in a desired direction as the wing rotates.
