Abstract: An aerodynamic toy having a circular-shaped rotatable, free-flight body of generally convex/concave shape is provided. A downwardly extending rim portion integral with and forming a smooth continuous curve with the body acts in flight as a primary air foil. Spiral-shaped air spoilers are provided on the upper surface of the convex-shaped body.

Abstract: An aerodynamic, saucer-shaped toy is provided for use in throwing games. The body of the toy is provided on its convex, upper surface with a plurality of radial extending air spoilers. These spoilers provide discontinuities to the flow of air so that in flight the air flow over the convex surface of the aerodynamic toy is disrupted, creating a turbulent air layer over the moving surface thereby somewhat reducing aerodynamic drag. A depression can be provided in the aerodynamic toy, centrally located in the convex surface, in which can be provided additional spoilers, as desired.

Abstract: An aerodynamic toy is provided for use in throwing games. The toy is shaped somewhat like a saucer and its body is provided on its convex sides with radial elevations. These provide discontinuities to the flow of air so that in use the air flow over the convex surface of the aerodynamic toy is disrupted thereby creating a turbulent air layer over the moving surface and reducing aerodynamic drag. An openable central compartment on the concave side may be used to contain batteries and a switch to power lights. The latter are supported by clips near the rim of the saucer.
