ABSTRACT:
A gliding parachute of the flexible, multi-cell airfoil type having a length to width ratio in the range of approximately 2:1 to 2.85:1, a maximum camber height to chord ratio in the range of approximately 0.1:1 to 0.2:1, a wing span to load attachment distance ratio of approximately 2:1, and an attachment point approximately 25% to 45% of the chord aft of the leading edge. The suspension lines and the fabric sections of the wing are dimensioned to impart a side to side curvature to the inflated wing. The gliding parachute has superior maneuverability and lift. A special pilot chute and bridle assembly are provided so that upon deployment of the main chute the pilot chute will automatically collapse to substantially reduce its drag, thereby improving the glide ratio of the main parachute.
