摘要： A throwable boomerang includes an open center polygon defining a closed ring having upper and lower surfaces including from three (3) to eight (8) connected linear segments and a plurality of tabular shortened, generally rounded, rearward-projecting members extending outwardly and downwardly from said ring each along and aligned with the axis of one of said linear segments, the peripheries of said tabular member being arcuate with each segment comprising an outwardly facing airfoil having a leading edge with a continuously varying angle of attack along the segment length, with the inner trailing edge of the airfoils of all of said segments conforming to a single plane, the leading airfoil edge of each of the segments being above the vertical midpoint of the segment proximate the extending tabular member and transitioning to being below said vertical midpoint at an end of the segment which is remote from the extending tabular member.
