ABSTRACT:
The ground impact velocity of a parachutist is reduced by a single, length-shortening, retraction device mounted between the parachute riser webbings. The gas generator-activated retraction device is activated by a ground proximity device based on electromagnetic or ultrsonic radiation reflected from the ground. The retraction device is fully integrated, eliminating any need for wires or connectors. An alternative design for the ground sensor is a wire-dangled mechanical ground sensor. The system allows steering of the descending parachute.
