Pressure and canopy profile data of 20/sup 0/ conical ribbon parachutes during inflation
Technical Report
·
OSTI ID:7094626
The Sandia Laboratories established wind tunnel data of 3-ft ribbon parachute models concerning canopy profiles, drag forces, and pressure distribution during the period of inflation. The data were analyzed at the University of Minnesota, and resulted in presentations of canopy profile coordinates, drag areas, and pressure distributions versus time. Pressure integration about the canopy surfaces as given by the established coordinates provided calculated areas which agreed satisfactorily with measured drag areas. Also, radial force coefficients of the various configurations were established. The results of this study are intended to serve as background information for related investigations such as studies concerning parachute dynamics, stress analysis, etc. 52 figures, 47 tables.
