A test was conducted in the 16-ft supersonic tunnel to obtain drag, inflation, and stability characteristics of a metal ballute, a cloth ballute, and three hemisflo parachutes 5-, 10-, and 15-percent porosity. The cloth and metal ballutes were investigated at Mach numbers of 2.5 and 2.9, respectively, at a dynamic pressure of 120 psfa. The hemisflo parachutes were investigated at a Mach number of 2.6 at a dynamic pressure of 120 psfa. The drag coefficient of the hemisflo parachutes decreased as canopy porosity increased. There was no discernible effect of canopy porosity on stability of the parachutes.
