Abstract
A straight boomerang which may be massed produced and which provides consistent and reproducible flight characteristics, is constructed based on an analysis of the aerodynamic forces which are operable on the boomerang during its flight and the use of a material which eliminates or minimizes density gradients along both the longitudinal axis and the width axis. In addition, the weight verses lift area ratio is chosen to facilitate the transition of the longitudinal axis of the boomerang immediately after release from a vertical position to a horizontal position which is key to a successful flight pattern.
