A rotating circular aerofoil system that includes a disc body that has an aerofoil shape in cross section. The air foil shape has an angle of attack that is symmetrical. The disc body's includes a circular inner edge which forms a circular center opening and the disc body's leading edge. The disc body also includes an outer edge that forms the trailing edge. Intersecting ribs extend across the center opening and include a shaft opening that attaches to a rotating shaft. Formed on the top and bottom surfaces of the disc body are evenly spaced apart, extending T-shaped or L-shaped fins. In one embodiment, an air blower or impeller is attached to a hollow shaft linked to an air pump. When the air pump is activated, air is delivered to the air blower and impeller that distributes the air over the top surface of the disc body to improve lift.

The present invention is an electric air vehicle that uses a new kind of propeller referred to as rotor with circular solid disk shape with blades on one side of the rotor and flat surface on the opposite side. When the rotor is in rotation it has the advantage of exhibiting weightlessness and the air flow over the blades is smooth and occurs on one side of the rotor compare to existing propellers that air flows on both side of the blade. Flight control is achieved by mechanically tilting the rotor for the air vehicle pitch and roll movement without a need for additional flight control surfaces.

The present invention discloses a low-noise novel thruster, in which a rotor casing is located at an air inlet side of a stator casing, at an inner middle portion of the rotor casing a rotor core is provided which is driven to rotate by a driving module; a rotor core is provided at in inner middle portion of the stator casing; the rotor casing is of a streamlined cylindrical structure with unequal diameter, and the main body of the rotor blade is parallel with the axial direction, and provided with a smooth curve in the rotating direction of the blade adjacent to an edge portion of an air inlet side. The present application provides a new thruster, which has same energy consumption and safety as propellers, but at a significantly greater thrust than the propeller, the more significant the advantage is at higher speeds.
