| Number | Title | Issue Date |
| 4386748 | Aircraft with counterrotating members A rotationally symmetrical supporting member provides lift in response to movement of air over its upper surface, and such air movement is produced by the impeller of a coaxially arranged drive unit, the base of which is connected to the supporting member... | 06/07/1983 |
| 4370824 | Aerial device An aerial device in the form of a disc which can be "sailed" in the air by throwing it in a manner to impart rotation to the disc. Vanes, holes and/or conduits are provided in the disc to force air from the top side or perimeter or other location to the u... | 02/01/1983 |
| 4312483 | Aircraft with circular wing An aircraft is provided with a circular wing member which is rotatably mounted to a fuselage member. The circular wing member provides lift for horizontal flight and also provides gyroscopic stabilization of aircraft attitude. The circular wing member is ... | 01/26/1982 |
| 4307856 | Annular wing An annular wing particularly suited for use in supporting in flight an aircraft characterized by the absence of directional stabilizing surfaces. The wing comprises a rigid annular body of a substantially uniformly symmetrical configuration characterized ... | 12/29/1981 |
| 4301981 | Aircraft with rotary wing 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 ... | 11/24/1981 |
| 4296892 | Spherical living module or space A substantially spherical human living module or space has a plurality of pontoons projecting from its lower hemisphere. It is preferably arranged to be self-propelled, as a vehicle, and the pontoons are preferably extensible and retractable. In a version... | 10/27/1981 |
| 4273302 | Aircraft with counterrotating members A rotationally symmetrical supporting member provides lift in response to movement of air over its upper surface, and such air movement is produced by the impeller of a coaxially arranged drive unit, the base of which is connected to the supporting member... | 06/16/1981 |
| 4269375 | Hybrid annular airship An airship has a gas-containing annulus contained by the circular base portion of framework the central portion of which extends above the annulus. The capacity of the annulus in accordance with one embodiment is such as to render buoyant a weight equal a... | 05/26/1981 |
| 4215832 | Inverted cone aircraft An aircraft is disclosed which includes a body having the shape of an inverted cone with a downwardly extending rim formed about the edge thereof and a triangularly shaped tail section. The aircraft can be constructed as a glider or a powered device and s... | 08/05/1980 |
| 4214720 | Flying disc A flying disc capable of vertical takeoff, hovering, or powered horizontal flight. The disc includes a discoidal wing that is circular and includes a convex surface on an upper side and a concave lower surface. The wing also includes an inward leading edg... | 07/29/1980 |
| 4208025 | Rotary wing aircraft An aircraft rotary wing aerofoil assembly comprising a generally planar annular frame supporting radially inner and outer sets of aerofoil blades, each set being disposed to form an annulus and supported on the frame for rotation about a common axis, and ... | 06/17/1980 |
| 4196877 | Aircraft An aircraft comprising a generally annular wing structure surrounding a circular central structure to form an annular air duct, a pair of fuselages extending longitudinally at opposite sides of the aircraft, and rotor blades extending radially across the ... | 04/08/1980 |
| 4184654 | Rotor aircraft An aircraft useful as a toy or as a personal craft which includes a plurality of blades freely rotatably mounted on a spherical body supported by landing means. The blades are hinged onto arms to swing up and down for upward flight or downward landing. Fu... | 01/22/1980 |
| 4165848 | Rotary thrust device including axially elongated rotor rotatable in casting having elongated fluid intake and discharge slots A fluid flow device comprises a rotor housed in a casing having slot-like intake and outlet openings. Groups of such devices can be used to form an aircraft propulsion system by drawing-in air from above through the intake openings and forcing the air dow... | 08/28/1979 |
| 4120468 | Remotely piloted vehicle The vehicle is constructed from a flat disc recessed in a slot in a thin, pencil-like fuselage having aft and front propulsion engines and mounted for rotating about the center of the disc and about an axis extending transversely to the disc and to the di... | 10/17/1978 |
| 4117992 | Vertical lift device A vertical lift device comprised of a generally vertically disposed cylindrical tunnel, open at the top and bottom ends, with a driven propeller axially mounted at the open top end to direct a stream of air downwardly through the tunnel. A first portion o... | 10/03/1978 |
| 4050652 | Gyro foil A flying vehicle in the form of a fixed structure fitted with propulsion engines and in the form of a fixed wing and tail section mounted to a pair of counter-rotatable discs, one below and one above the fixed structure, with the discs when rotating provi... | 09/27/1977 |
| 4044972 | Aircraft with circular wings An aircraft has two concentric wings of substantially equal diameters, the wings being connected to each other and stayed by an elongated central corridor which is located beneath a central engine duct disposed in the plane of the upper wing.... | 08/30/1977 |
| 4032084 | Helicopter type aircraft with ground effect structure The aircraft in the nature of a helicopter is movable in a vertical direction when being raised from the ground or landing thereon. The body of the aircraft is toroidal in form, that is to say, the shape of a doughnut having a central aperture. The centra... | 06/28/1977 |
