    摘要: A launcher (20) for a flying object, such as a boomerang (21), having a body that includes a plurality of wings (31). The launcher includes a stop (23), against which the object rests at a point (27) on its body. A moving member (25) engages one of the wings of the object so as to impart forward motion thereto, such that the object is propelled forward from the launcher with a rotational moment about the stop. The boomerang is preferably made from a sheet (50) of material which is cut to form the plurality of wings, joined at a vertex (28), wherein one or more of the wings are folded to produce lift flaps (34, 35).

    摘要: A boomerang (20) comprising a central hub (22) having a generally central aperture (24) therein, a plurality of equally spaced, cambered blades (26,28,30,32,34) extending generally radially outwardly from the hub, a tip (26',28',30',32') depending generally downwardly from each of the blades (26,28,30,32) but one, the included angle between each blade and its respective tip being greater than 90°, and a weight on the blade (34) without a tip so that the boomerang (20) is mass balanced about an axis through the center of the hub (22). The included angle between each successive tip and its respective blade may increase in either the clockwise or counterclockwise direction around the boomerang.

    摘要: A boomerang comprises a member having two arms 11, 12 including an angle in an L-shape. At least one arm itself has two portions 13, 14 including an angle, but this angle is in the opposite sense to the angle of the L and preferably larger in magnitude. There may be one or more apertures 35-37 in the region of the junction 17 between the two arms, and when there is a plurality of apertures they may be arranged linearly, decreasing in size towards the leading edge of the region as the boomerang spins.
