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 WL 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.
