A system and method of constructing a system for delivering cargo by
airdrop are provided. In short, the system uses rotor blades to slow the
descent of cargo dropped from an aircraft. In one example of one
embodiment, a frame is secured to a cargo pallet and at least one rotor
blade is secured to the frame. The rotor blade is secured to the frame in
a position such that it causes the cargo pallet and the frame to rotate
in air when dropped from an elevation. In another embodiment, the rotor
blade may be extendable and extend during flight.
