The feasibility of using existing propellant actuated device PAD type rockets and other appurtenances, such as ground sensor and safe arming systems was investigated to reduce the ground contact velocity of air-delivered cargo. Specifically considered were cargo loads in the range of 2000 to 35,000 lb which were decelerated by parachute to a velocity of 40 to 60 fps then, by the use of PAD type retrorockets, the velocity was to be further reduced to 25 fps just prior to ground contact. Results of the study indicated that an aerial recoevery system consisting of parachutes and PAD type retrorockets can provide a reduction of approximately 60 percent in weight and volume and, also, provide a saving in cost when compared to the all-parachute recovery system.
