Abstract : A six-month parametric study program was conducted of performance, weight and volume characteristics of typical configurations of both the slow descending and loiter type systems suitable for lightweight expendable payloads released from aircraft or rockets. Typical configurations investigated were drag devices, rotors, gliders, powered gliders, free and tethered balloons. Descent systems were studied for descent velocities of 2, 4 and 8 FPS while loiter systems were considered for times ranging to 600 minutes for a payload range of 0.1 to 50 pounds and altitudes up to 50,000 feet. Volume which is related to SLODS (Slow Descent Systems) weights was considered to be the most important parameter for the investigation. (Modified author abstract)
