61	Circular wing aircraft	US3572613D	1969-02-17	US3572613A	1971-03-30	PORTER ARTHUR
A hollow, circular housing is open about its periphery and has a central opening in its top. Circumferentially spaced vanes extend between the central opening and the open periphery to direct air flow from the central opening radially outward through the open periphery and across the upper and lower surfaces of an annular airfoil wing secured to the housing. A pair of jet engines at the housing periphery operate to rotate the housing to effect said movement of air.

76	VERTICAL TAKE OFF AND LANDING CLOSED WING AIRCRAFT	US15593554	2017-05-12	US20180244381A1	2018-08-30	Carlos Alexander Fenny; Rohn Lee Olson; Andrew James Zahasky
An aircraft capable of vertical takeoff and landing, stationary flight and forward flight includes a closed wing that provides lift whenever the aircraft is in forward flight, a fuselage at least partially disposed within a perimeter of the closed wing, and one or more spokes coupling the closed wing to the fuselage. One or more engines or motors are disposed within or attached to the closed wing, fuselage or spokes. Three or more propellers are proximate to a leading edge of the closed wing or the one or more spokes, distributed along the closed wing or the one or more spokes, and operably connected to the one or more engines or motors. The propellers provide lift whenever the aircraft is in vertical takeoff and landing and stationary flight, and provide thrust whenever the aircraft is in forward flight.

A rotor blade rotation system includes two or more rotor blades, each rotor blade in mechanical communication with a hub and pivotable about an axis of rotation, a bearing plate comprising a rotating portion and a non-rotating portion, a fold linkage coupled to the rotating portion of the bearing plate and in mechanical communication with the rotor blade, and an actuator coupled to the non-rotating portion of the bearing plate and operable to reposition the bearing plate from a first position to a second position such that the folding links pivot the rotor blades from a deployed position to a forward folded position.

An aerodynamic platform or spacecraft including a habitable 1G centripetal force rotating gravity producing interior corridor within an aerodynamic shell and an aerodynamic drone booster launch system with reentry and reuse capability.
79	Disc-shaped turbo-jet aircraft	US15166005	2016-05-26	US09550566B2	2017-01-24	John Francis Henning, Jr.
A disc-shaped aircraft including an airfoil having a convex upper surface and a planar lower surface with the edges of the surfaces meeting at the periphery of the disc and having a plurality of rotational mini turbine jets affixed sequentially at the edge of the circumference of the disc, the turbine jets effecting vertical, horizontal, and directional thrust under computer and pilot control. Stable flight is maintained by an internal gyroscopic counter-rotating rotor blade system, individual control of the turbine jets, and a series of retractable flaps.
80	Saucer shaped gyroscopically stabilized vertical take-off and landing aircraft	US12387770	2009-05-07	US20100282918A1	2010-11-11	Herbert Martin
An aircraft that is housed within a gyroscope providing for improved flight stability that includes an inner hull which remains stationary within a rotating outer hull. A rotating sine-wave ring is used to activate and move a plurality of pistons which will intake air from above the upper surface of the inner hull configuration and create a negative pressure on the aircraft. The craft contains compression chambers which receive the air and which feed the various impeller thrusters which are rotational within three-fourths of a hemisphere.
