Abstract
A flying disc (,) comprises an outer rim (,) encompassing a contiguous thin central plate (,). The rim has a cross-section comprising an outer surface (,), top and bottom edges (,), and fillet curves (,) joining the top and bottom edges to the respective top and bottom surfaces (,) of the central plate. The total height (,) of the rim is the vertical distance between the top and bottom edges. A second height (,) is the vertical distance from the bottom edge to the point (,) where the top fillet curve becomes parallel to the top surface of the central plate. The second height should be between 55% and 80% of the total height in order to achieve balanced aerodynamic lift and thus a straight flight.
