Pressure and profile data of 20/sup 0/ conical ribbon parachutes
Wind tunnel data of 3-ft ribbon parachute models concerning canopy profiles, drag forces and pressure distribution are presented. The data were analyzed and resulted in presentations of drag coefficients, projected diameters, and drag areas of reefed and unreefed parachutes versus geometric porosity and suspension line length as well as in tables and graphs of canopy coordinates and related pressure distributions. Pressure integration about the canopy surfaces as given by the established coordinates provided drag forces which agreed satisfactorily with measured forces. Also, radial force coefficients of the various configurations were established. Results are intended as background information for related investigations on parachute dynamics, stress analysis, etc. The data are presented in two volumes, Volume I being a summary report, while Volume II contains the bulk of the data.
