ABSTRACT:
A boomerang in the form of a generally planar ring having a circular outer edge and an inner opening. The opening is shaped so that equiangularly spaced apart planar wing elements are formed which have greater radial width than the portions of the rings which span between them. Each wing has a symmetrical V-shaped airfoil protruding from it so that the boomerang exhibits similar aerodynamic properties whether it is thrown by a left or right-handed person.
