81 Aerodynamic vehicle having a variable geometry, co-planar, joined wing US10801750 2004-03-16 US07249734B2 2007-07-31 Rudolph N. Yurkovich
An aerodynamic vehicle is comprised of a pair of forward wing sections and a pair of rearward wing sections that are connected together by four pivot assemblies as a four-bar linkage. The four-bar linkage surrounds an opening provided between the forward wing sections and rearward wing sections. Movement of the wing sections varies the cumulative area of the wing sections, and adjusts the shape of the opening between the forward wing sections and rearward wing sections. Movement of the wing sections improves the aerodynamic performance of the vehicle and allows the wing sections to assume optimum configurations for operation of the vehicle at high speed and low speed.

84 Circular vertical take off & landing aircraft US09967840 2001-10-01 US06581872B2 2003-06-24 Eric Ronald Walmsley
A circular VTOL aircraft with a central vertically mounted turboprop engine (14), driving contra-rotating co-axial propellers (24), above a central jet engine, or engines (12), horizontally mounted on a turntable pod (11) which is steerable through 360 degrees. The turboprop provides vertical thrust from contra-rotating propellers compressing air from an upper circular intake (5) downward through a funnel-shaped rotor-chamber (6) to a circular vent (10) at the base of the craft. The resulting column of compressed air supports the craft during take-off, hover and landing operations and provides a cushion of air in normal flight. The horizontally mounted jet turbine provides main thrust for horizontal flight and vectored thrust for VTOL. The passenger cabin (21) is circular and is situated in the main body of the disc-shaped craft. Fuel tanks are situated around the circumference of the craft to maximise fuel capacity. The flight-deck (2) is situated at the top center of the craft, above the engine unit (15), which is detachable.

86 Device for generating an aerodynamic force by rotational movement US09509688 2000-06-16 US06318962B1 2001-11-20 Eduardo Bittencourt Sampaio
A generator of aerodynamic force by rotational movement, by means of a device which, starting from a rotational movement, induces a field of velocities in the surrounding fluid, which produces a difference in pressure on a surface, which in turn results in an aerodynamic force. The rotor element (1) is set in rotation at high speed by a motor (3). The rotational movement of the rotor element causes the fluid in which the device is immersed to assume a rotational movement, the velocity of the fluid layer that is in contact with the cylinder being equal to the velocity of a point at the surface of the cylinder. The planar element (2) separates the fluid into two regions. The fluid in the region below the surface is motionless, whereas the fluid above the surface is in motion. Since the higher the velocity of the fluid the lower its pressure, the fluid in the region below the surface exerts a higher pressure than that exerted by the fluid in the region below the surface. This difference in pressure results in a force that acts on the surface.

For an aircraft (1) having a balancing torque and including a motor-driven propeller (5) arranged on a central axis (3), and a useful load container (6), a solution should be provided which would insure that the aircraft is capable of carrying useful loads in a stable flying attitude and with simple control means.This is achieved by that the central propeller (5) driven by the drive motor (4), on one hand, and relative thereto, the motor (4) and/or torque-balancing means arranged thereon, on the other hand, are rotatable in opposite directions and together are supported for rotation relative to the useful load container.At that, the drawing figure to be published: FIG. 1.
88 Aircraft with a ducted fan in a circular wing US9246 1993-01-26 US5303879A 1994-04-19 Franz Bucher
The aircraft comprises a rotor with a vertical axis arranged in a housing for generating a lift exceeding the weight of the aircraft. The housing is essentially shaped as a circular wing. A first way of guiding air is provided for controlling the air stream generated by the rotor, by means of which the position of the aircraft can be controlled in hovering flight. From hovering flight, the aircraft can be moved into a cruise flight, where the lift of the aircraft is generated aerodynamically by the circular wing of the housing and its forward thrust by a propeller. For the transition between hovering flight and cruise flight, a second way of guiding air is provided for controlling the pitch of the aircraft. The structure for the second way of guiding air is arranged outside a zone defined by the air stream of the rotor.
89 Method and means for generating a force US520638 1990-05-08 US5155992A 1992-10-20 Robert E. Follensbee; Guy D. Riva
A method and means for generating a force. A flared body is enclosed in a shroud to form one or more ducts of axially diminishing cross-section for accelerating and directing the discharge of a fluid introduced into the ducts under pressure. A cambered vane is positioned at the exit of each duct, in the path of the accelerated fluid discharge. Fluid passing over and under each vane produces a force aligned axially with the body and in the direction of flow of the fluid in the associated duct. In a preferred embodiment a conically-shaped body and surrounding shroud form an annular duct for air delivered to the mouth of the duct by a compressor. The vane is an annular airfoil.
90 Circular airplane US332489 1989-04-03 US5054713A 1991-10-08 Lawrence W. Langley; Hal L. Moses
The invention is a circular airplane with an oblately spheroidal body which derives lift from a wall or ribbon jet exhausting over its upper surface. The jet is produced by a mixed flow fan driven by an internal combustion or gas turbine engine within the body. A fixed guide van assembly removes the swirl from the outlet flow of the mixed flow fan. The jet exiting from the fixed guide vane assembly follows the curved surface of the body, exhausting downward, and produces lift. The magnitude of lift produced in each quadrant of the airplane may be reduced for thrust vectoring by flow control gates which partially block the flow of air from the fixed guide vane assembly. Rotation control vanes introduce a controlled swirl into the flow of air from the fixed guide vane assembly to effect rotation of the airplane. Actuators for flow control gates and rotation control vanes, and a flight control system, are provided.
91 Aircraft with counterrotating members US956005 1978-10-30 US4273302A 1981-06-16 Heinz Jordan
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 so that counter torque from the drive unit imparts rotational movement to the supporting member. A carrier which may hold a load or supporting steering flaps is rotatably mounted in relation to the supporting means and to the driving unit.
