ABSTRACT:
A flying disk characterized by a saucer-shaped hull having a convex top and a concave bottom surface and fitted with three side ports jointly defined by the rim of the disk and by the rear edges of three airfoils attached to the rim and the concave bottom surface of the disk. The airfoils are cupped and extend inwardly toward the center of the disk. A tubular central port is provided in the center of the hull and the tips and mounted portions or legs of the triangularly shaped, inwardly extending airfoils are positioned in planar relationship with the bottom opening of the central port. Aerodynamic lift is achieved when the disk is thrown forward with a spinning motion as low pressure is created on the convex upper surfaces of the disk hull and the cupped airfoils, while high pressure is created on the bottom concave surfaces of the hull and airfoils.
