PERFORMANCE OF FLEXIBLE PARACHUTE MODELS AT MACH NUMBERS FROM 1.5 TO 4 (U)
Abstract
Tests were conducted to determine the drag and stability characteristics of 4 fabric parachute models. Two models were tested from Mach 1.5 to 3 at dynamic pressures corresponding to altitudes of approximately 65,000 to 102,000 ft, respectively, to observe their reefed inflation characteristics. A previously untested model was also investigated in this Mach number range but without reefing. The fourth model was investigated without reefing at Mach 3 to 4 where pressures corresponded to altitudes of 102,000 to 124,000 ft, respectively. This model was also tested at Mach 4 with increasing pressures (simulating altitudes from 124,000 down to 77,000 ft) to gain additional information concerning performance under more severe flight conditions. The drag and stability data for each configuration consisted of high-speed schlieren and sideview movies and oscillograph drag traces. (Author)
