Steerable Parachutes
Abstract
The Parawing, the Parafoil, the Sailwing and the Volplane achieve glide ratios of better than 3 to 1. They are lowering payloads of 6000 pounds from altitudes of 20,000 feet at dynamic pressures up to 100 per square ft. Their flight characteristics are more representative of gliders than of parachutes. This paper discusses the historical and technical development, defines aerodynamics stress analysis, deployment characteristics and flight performance, as well as showing some areas of operational application with emphasis on decoupled landing of logistics shuttle spacecraft.
