Effects of Canopy Geometry on the Spinning Characteristics of a Cross Parachute with a W/L RATIO of 0.264
Abstract
The effects of cloth permeability, number of suspension lines, suspension line length, and hem configuration on the spinning characteristics and aerodynamic drag force of the cross parachute were investigated in a wind tunnel. Forty-inch-diameter models with a canopy arm width-to-length ratio (W/L) of 0.264 were tested at various velocities from 50 feet per second to 300 feet per second. Tests were conducted with a conventional cross parachute and with modifications to the skirt hem which represented an interpanel cord and a band of cloth. The width of the cloth band was ten percent of the canopy diameter.
