Abstract:

The stability and drag characteristics were determined for a series of fabric parachutes over the Mach number range of 1.5 to 6. Various parachute designs employing porous and ribbon materials were tested at dynamic pressures corresponding to altitudes of approximately 63,000 to 143,000 ft for the above Mach number range, respectively. Drag modulation by reefing was successfully attempted on one parachute configuration at Mach numbers 1.5 to 3. Another configuration was tested for strength of construction at a higher pressure level corresponding to an altitude of 109,000 ft at Mach 6. The data obtained in these tests consisted of high-speed movies, both sideview and schlieren, and oscillograph drag traces. Author
