Abstract : Several hyperflo and parasonic parachutes and one hemisflo parachute were tested in the 16-ft supersonic wind tunnel to obtain drag, inflation, and stability characteristics at a nominal Mach number of 3.0 and a nominal free- stream dynamic pressure of 120 psfa. The effects of various types of roof mesh and material on the aerodynamic characteristics of the parachutes were obtained. These data show that the hyperflo parachutes and higher drag loads but less inflation and stability than the corresponding parasonic parachutes with the same combination of roof mesh and material. Differences on roof designs resulted in a drag variation of approximately 25 percent for both the hyperflo and parasonic series of 4-ft nominal diameter parachutes.
