Model Studies of Inflation Uniformity of Clustered Parachutes

Abstract

The uniformity of the opening characteristics of free flying model parachute clusters with and without inflation aids was investigated. Models of 5 ft. nominal diameter with low stiffness index were fired from a compressed air catapult and the parachute forces versus time were recorded. The model tests showed that in clusters of three parachutes the configurations of the standard parachute with riser extension and the standard parachute with an internal canopy without riser extension had the best performance characteristics.
