DRAG AND DYNAMICS OF SINGLE AND CLUSTERED PARACHUTES IN FREESTREAM, AND WITH WAKE AND GROUND EFFECTS

Abstract

Results of wind tunnel studies concerned with transient and steady state performance of single and clustered parachutes in cargo extraction systems are presented. In Part I, circular flat and ringslot canopies single suspended and in clusters of 2, 3, and 4, were deployed in freestream, in the wake of an aircraft, and near a simulated ground. As a further means of analysis, wake pressure surveys were performed on the DHC-4 Caribou and the C-130 Hercules aircraft and are presented in Part 2.
