Abstract: A rotating airfoil aircraft utilizing blown air from a centrifugal fan located at its center to produce lift by causing airflow to travel over the upper surface of the airfoil and outwardly and downwardly from the lower surface of the airfoil. The airflow over the upper surface produces lift by causing a reduced pressure in the blown air current and the downwardly directed air produces an upward lift. This lifting force is used in connection with other lift produced by various factors including the airfoil traveling laterally through ambient air and, particularly during takeoff and landing, by means of the downward exhaust of an engine such as a jet engine. The rapidly rotating airfoil aircraft provides an advantage of providing the leading edge an opportunity to cool during a major portion of each rotation, thereby reducing the effective degree of leading edge heating caused during lateral flight.

Abstract: An aircraft utilizes a buoyant evacuated rotating envelope to provide at least a portion of the lift required. The rotating envelope may be in the form of a disk, cylinder or other suitable shape. In one embodiment, an evacuated rotating envelope in the form of a disk is utilized. The disk is provided with a central core tube with at least one jet engine mounted therein. The deflection of the exhaust causes rotation of the envelope. A non-rotating payload compartment is mounted to the rotating envelope by bearings. Structures are provided for deflecting the exhaust to be utilized for lateral propulsion as well as for stabilizing the payload compartment to prevent rotation. Two other embodiments utilize rotating cylinders which may be rotated either by a jet engine mounted within a core tube or by an off center jet engine which drives the cylinder.

Abstract: A hybrid multiplexing method and communications system for controlling transmission of information between a plurality of remote terminals and a shared central facility over a common communications channel. The remote terminals are synchronously polled to ascertain whether or not the remote terminals desire access to the central facility. Asynchronous polling is utilized to establish communication between the central unit and the remote terminals desiring access to the central unit.
