Abstract
A gas-powered landing velocity attenuator for reducing the final descent velocity (and consequent ground impact load) of a parachutist or parachuted cargo. Immediately prior to impact, the gas source powers a device for drawing the load (either a parachutist or cargo) closer to the canopy of the paracute. In a first preferred embodiment, the load and the canopy are brought closer together by a single action piston and cable assembly powered by the gas source. A second embodiment uses an inflator assembly connected to an air bag or a braided tube to decrease the distance between the load and the parachute canopy.
