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.

[ I claim:] [1.]1. An aircraft, comprising:a circular shaped airfoil having an upper surface;means for rotating said airfoil, wherein said means for rotating said airfoil includes an engine for causing gaseous fluid flow directed towards controllable deflectors, said controllable deflectors being adjustably adapted to cause selective amounts of rotation and lift; andmeans for causing airflow across said upper surface of said airfoil to produce lift of said airfoil.
