Abstract:

A low-cost radar actuator for use as a component in a delayed-opening parachute aerial-delivery system has been developed. This device is known as HADOPAD High-Altitude Delayed-Opening Parachute Actuating Device. The device, based on radar principles, will open a main recovery parachute at either of two preset heights 1000 or 1700 ft above the ground. The complete system utilizes a drogue-parachute stabilizing stage for free fall from high altitude followed by a main- parachute recovery stage which is initiated at low altitude by the radar actuator. Limited field testing of the radar actuator at Fort Devens, Mass. has shown the feasibility of the device as a parachute actuator, but some additional engineering and complete environmental tests are necessary before initiation of quantity production. Forty actuators were constructed by HDL during the research and development phase. Author
