For the case of a cross-shaped boomerang,<br />
where V, ω and a are the velocity, spin speed<br />
and radius of the boomerang as before, and<br />
A S = πa 2 (the swept area of the boomerang).<br />
, and equations 1, 5 and 7 can be arranged to give<br />
From equations 2, 3 and 6, we find that the<br />
radius R of the circular flight path is<br />
independent of spin speed ω and forward<br />
velocity V, and that it is a constant for a given<br />
boomerang:<br />
R = (4J) / (ρC L πa 4 ) (7)<br />
