Abstract: Upper and lower rectangular canopies are connected by a plurality of transversely spaced vertical airfoil shaped ribs to define a plurality of longitudinal air flow chambers. Suspension lines are connected to selected ones of the ribs and are arranged in longitudinally spaced and transversely extending rows. Cells are defined which consist of a plurality of adjacent chambers between any two transversely adjacent suspension lines. Some of the cells have three chambers while others have two chambers. The suspension line dimensions and trim angles are used to impart multiple pressure centers and different arc anhedral shapes to improve various characteristics of the parachute including opening, stability and accuracy.

Abstract: Each suspension line of a multi-cell gliding parachute is connected through a lower loop of a primary reinforcing tape folded over on itself. The upper overlying segments of the primary reinforcing tape extend partially across and are stitched to one side of a corresponding fabric rib connected between upper and lower fabric canopies of the parachute. The upper ends of the segments terminate below the upper canopy and are connected to a secondary reinforcing tape also stitched to the rib and spaced from the upper canopy. The upper segments of the primary reinforcing tape and the secondary reinforcing tape form a Y, T or other configuration serving to distribute the load from the suspension line without puckering or otherwise altering the preferred airfoil configuration of the upper and lower canopies.

Abstract: A slider constructed of fabric is removably connected between the load suspension lines of a gliding parachute. During deployment of the parachute the slider moves longitudinally down the suspension lines to gradually restrain their transverse spreading. This slows down the inflation of the parachute and prevents dangerous explosive openings thereof. The slider is thereafter removed from the suspension lines in flight by pulling downward on a pair of handles to release tear away connectors. This reduces drag and makes the gliding action of the parachute quieter and more efficient.

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.
