Conceptual design for an airdrop system from a 500 ft. altitude for payloads from 2,000 to 35,000 lb using a spinning ballute for cargo extraction and initial rotor spin-up and an autorotating inflatable flexible rotor for terminal descent are reported. Ballute weights and rotor system size and weights are evaluated for systems with and without a flare maneuver to meet acceptable impact velocity conditions. Operational requirements and a preliminary estimate of reliability are presented. Design and free-flight testing of a 5-ft. diameter model inflatable rotor are described. (Author)
