A boomerang is like a propeller

A boomerang is like a propeller

The two wings of a boomerang are arranged so that the leading edges are facing in the same direction, like propeller blades. Propellers create a forward force by spinning the blades.

If you throw a boomerang, as you do with a Frisbee, you may assume the forward motion would be up, and the boomerang would fly up until it stopped spinning and gravity pulled it down again. If you held it vertically when you threw it, as is proper, it seems that it would fly off to the right or left. But that is not what happens.

Why boomerangs fly

Why boomerangs fly

The wings are set at a slight tilt. They have an airfoil design - rounded on one side and flat on the other - which gives a wing lift...
