ABSTRACT:
An aerodynamic device for being launched for flight through the air and having three inherent parameters of rotation while moving through the air, the first being a yawing vector imparted by the launcher as the device rotates about its own center of symmetry, the second being a roll vector as it rotates about an axis parallel to its direction of flight, and the third being rotation of the device very slowly about a center which is determined by the launching point whereby a boomerang action is provided. The device comprises a substantially annular body having three symmetrically disposed lobes extending radially outwardly therefrom, with each lobe being of a substantially undulated cross-sectional configuration to provide a subtle lateral curvature for the device which is critical to the flight behavior thereof, the lateral curvature of the lobes providing a lifting surface for sustaining the device in a state of levitation during movement through the air, and a reverse curvature at the tips of the lobes providing stabilization and control of the roll flight axis of the device.
