The record for maximum time aloft (MTA) is two minutes, 59.94 seconds the unofficial MTA record, which was witnessed but not thrown in a sanctioned competition, is an astounding 17 minutes, six seconds. The inter-national record for distance traveled before returning to the thrower is 780 ft (238 m), in a flight that lasted nearly 22 seconds. Those who are interested in competition can choose from a variety of events, including precision (returning as close as possible to the launch point) and endurance (making the most catches in a five-minute period). Recreational throwers simply enjoy playing a solitaire game of catch. When it returns to the thrower, it is caught safely at chest height, trapping it between open hands in a sandwich fashion. If there is any breeze, the boomerang must be thrown between 30° and 90° to the right of the on-coming wind (or to the left for a left-handed thrower right-and left-handed boomerangs are mirror images of each other).Īs the boomerang flies forward, it begins to slowly roll over (counterclockwise for a right-hander), ultimately flying horizontally with its flat side down. The release angle should be between horizontal and 15° above. At the moment of release, the thrower adds a snap of the wrist, as if cracking a whip. After drawing the arm backward, the thrower hurls the boomerang with an overhand motion, much as a pitcher would throw a baseball. Depending on wind conditions and the design of the particular boomerang, the upper portion may be inclined up to 30° outward. The boomerang should be almost vertical, with the thrower holding the lowest arm. It should be held near the end of one wing with the top (curved) surface facing the thrower's body. A similar effect can be seen with a spinning top: if the top's axis is not quite vertical, the upper portion of the toy travels in a circle around the axis.įor a successful flight, the boomerang must also be thrown correctly. In addition, the spinning motion creates gyroscopic precession, which pulls the boomerang into a circular path. The wing profiles create the same lift effect that makes airplanes fly. During flight, the boomerang spins rapidly (about 10 revolutions per second). One is the arrangement of the arms, and the other is the airfoil profile shape that allows the arms into wings. Two design components give the boomerang the capability of circular flight. (Some sources describe all aerodynamic "throwing sticks" as boomerangs, separating them into "returning" and "nonreturning" categories.) Traditional designs are V-shaped, but newer versions may have irregular shapes or more than two arms. The term usually refers to an object made to follow a circular flight path that returns it to the thrower. A boomerang is an aerodynamically shaped object designed to fly efficiently through the air when thrown by hand.
