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.
