For the case of a cross-shaped boomerang, where V, ω and a are the velocity, spin speed and radius of the boomerang as before, and A S = πa 2 (the swept area of the boomerang). , and equations 1, 5 and 7 can be arranged to give From equations 2, 3 and 6, we find that the radius R of the circular flight path is independent of spin speed ω and forward velocity V, and that it is a constant for a given boomerang: R = (4J) / (ρC L πa 4 ) (7) Sunday, May 30, 2010 18
• For the case of a boomerang with J=1/3 ma 2 , and equations 1, 5 and 7 can be arranged to give aω = (√2) V (8) which defines the "flick-of-the-wrist" needed to make the boomerang fly properly. Sunday, May 30, 2010 19
