In the case of boomerang it is also acting on the
same principle – The Bernoulli’s principle for the simple reason
that its design too is in the form of a horizontal half – tear drop!
How does a boomerang return to the thrower?
When you throw a boomerang you not only impart
great speed but also a certain amount of spin. The spin at the top is
more than at the bottom. Because the design enables the top of the wing
to move forward and at the same time spin forward as well, for the same
reason, the bottom portion spins not very fast but it surges forward and
effects the lift. Topside spins forward – backside spins backward.
Result? When the boomerang loses momentum the spin creates a gyroscopic
precession, which propels it to turn to the left enabling it to fly back
in a circle to whoever threw it.
