Abstract:

Effort was made to determine the requirements to sucessfully deploy or separate supersonic deceleration devices, both trailing and attacked, and to investigate techniques which can be used to inflate devices which otherwise might not be satisfactory. Various devices were investigatedAN ANALYTICAL STUDY OF DEPLOYMENT DYNAMICS WAS UNDERTAKEN TO ESTABLISH DEPLOYMENT CRITERIA AND AN INVESTIGATION OF THE CHARACTERISTICS OF INFLATABLE DEVICES WAS CONDUCTED TO DETERMINE INFLATION PRESSURE REQUIREMENTS. A system was developed to provide the required separation impulses. Various means of producing inflation pressures were evaluated, and an inflatable torus was investigated as a device to provide additional stiffness to a parachute canopy. Vehicle conditions at time of decelerator deployment encompass a speed range of Mach 1 to 4 at sea level, Mach 4 to 10 at 150,000 feet, and Mach 10 to 30 at 350,000 feet. Author
