ABSTRACT:
A boomerang with three convolute curved blades connected to a central hub, said blades being uniformly shaped and equally spaced about a central axis and has unique airfoil characteristics around the entire peripheral edge, the unique airfoil characteristic is an integral part of this invention; when the boomerang is thrust outwardly in a vertical position, it will create and maintain a forward flight pattern from the point of launching; it subsequently begins an upward flight until it momentarily stalls in the air, then makes a 180 degree turn to the left, reverses its forward flight and simultaneously rotates 90 degrees from vertical, taking on a horizontal, hovering type of flight pattern, and slowly returns to the point of launching; said forward and return flight pattern is desirable for safety as well as the appeal it has for competing in sporting events and tournaments as well as leisure play activities.
