Exploratory testing of supersonic ribbon parachutes in the NASA Ames 9-ft by 7-ft wind tunnel
Sandia National Laboratories conducted a test of ribbon parachutes in the NASA Ames Research Center 9-ft by 7-ft Supersonic Wind Tunnel. The Ribbon parachutes were 15 inches in diameter with Kevlar-29 suspension lines and nylon ribbons. Both 20-degree conical parachutes and hemisflo parachutes were tested behind two forebody shapes with several forebody diameters. Drag data and color Schlieren photographs were obtained over a Mach number range of 1.5 to 2.5 and a dynamic pressure range of 200 to 400 lbs/ft/sup 2/. Correlations of supersonic parachute drag with Mach number, forebody shape and diameter, canopy porosity, suspension line length, and inflated canopy diameter and stability are presented.
