#2440: ChopperChopper

Today’s invention is a new form of armament for military helicopters.

A belt of bullets (with no gunpowder) is fed up a tube inside the drive shaft of the main rotor (red circles).


This emerges from the end of a rotor blade.

At this point, a computer-controlled chopping device precisely times the separation of a bullet from its belt (white box), so that it flies off tangentially towards its target.

Each rotor blade can therefore act as a catapult arm, delivering enormous firepower (as long as the timing carefully avoids the tail rotor).
