A Lightweight, Disposable Air Cargo Delivery System
CopterBox is designed to deliver emergency supplies from a wide variety of aircraft with drop speeds of up to 140 knots. The corrugated paper box employs three rotor blades that use the principle of autorotative lift to slow it and its payload to a gradual descent prior to ground contact.

CopterBox makes economic sense in applications where a parachute would not be practical or prudent. CopterBox requires very little time and training to pack and rig prior to launch.

A welded wire rotor hub is used to protect the box prior to launch and to withstand the aerodynamic and centrifugal forces of flight during descent.
