Abstract: A rotating circular aerofoil system that includes a disc body that has an aerofoil shape in cross section. The aerofoil 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.

Abstract: A rotating circular airfoil system that includes a disc body that has an airfoil 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 airfoil shape's leading edge. The disc body also includes an outer edge that forms the airfoil shape's 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 fins. The fins extend continuously from the inner edge to the outer edge. When a rotating shaft is inserted into the shaft opening and imparts sufficient rotation to the disc body, the fins contact the air forcing it to flow along disc body's top and bottom surfaces and creating a lifting force.

Abstract: A rotating circular airfoil system (10) that creates lift when rotates about its axis (12) is disclosed. This circular airfoil is symmetrical about its axis and has a body-sectional-shape (14) similar to those of modern airplane wings. It is hollow in the middle to create a circular inner edge (16), which is the leading edge of the airfoil while its outer edge (18) is the trailing edge. Angle of attack (20) is symmetrically provided. Pairs of fins (22) are attached or embodied onto the top and the bottom of the airfoil. These sectional-tee-shape fins run radiately from the inner edge of the circular airfoil. Spokes (24) from the center of the circular airfoil attached to its inner edge enable it to be rotated by a turn-shaft that aligns to the airfoil axis through center hole (26). When this circular airfoil rotates about its axis in the air, the surrounding air is contact by the fins and forced to travel from the inner edge to the outer edge of the circular airfoil, as a result of the centrifugal action.
