Performance of Flexible Aerodynamic Decelerators at Mach Numbers From 1.5 to 6
Abstract
The fourth in a series of tests was conducted in the 40-Inch Supersonic Tunnel (A) of the von Karman Gas Dynamics Facility to investigate the drag and stability characteristics of a number of fabric parachute models in the Mach number range from 1.5 to 6 and of a 7.5-in. -diam, 80-deg conical balloon decelerator in the Mach number range from 4 to 5.5. The dynamic pressures at which these models were tested corresponded to altitudes of 64,000 to 140,000 ft at Mach 1.5 to 6, respectively. Two basic parachute families were investigated: a conventional hemisflo type parachute with varied amounts of reefing and a newly developed series designated as the hyperflo family of high performance parachutes with and without reefing. Tandem parachute models composed of two canopies with common suspension lines were also investigated. Drag and motion data for each configuration were recorded by oscillograph drag traces and high speed schlieren and regular movies. Selected data are shown.
