Institut für Flugsystemtechnik, through the American Institute of Aeronautics and Astronautics Aerodynamic Deceleration Systems Technical Committee.Includes bibliographical references.An experimental investigation and correlative analysis were conducted to determine the pressure distribution over the surface of parachute canopies during the period of inflation for the infinite mass case and to correlate pressure coefficients with inflating canopy shapes. Parachute canopy models of Circular Flat, 10% Extended Skirt, Ringslot, and Ribbon designs were tested under infinite mass conditions in a 9 x 12 ft low speed wind tunnel. External and internal pressure values were measured at various locations over the surface of the model canopies throughout the period of inflation, and generalized canopy profile shapes were obtined by means of photographic analysis.Deutsche Forschungsanstalt füe Luft- und Raumfahrt, e.V.AF61(052)-6816065606503Mode of access: Internet.Wind tunnels.fast(OCoLC)fst01175710Wind tunnels.ParachutesModelsTesting.ParachutesDeploymentTesting.Schmidt, P.
