Abstract

A parachute assembly including a pilot chute, pilot chute suspension lines, a main chute, and a main chute suspension assembly. The main canopy has an inverted apex and has an inner section of panels and outer section of panels joined by a reinforced crown seam. The seams are secured with two parallel longitudinal stitchings with a relatively elastic thread and a zig-zag stitch with a relatively inelastic, stronger, heat-resistant thread. There are only half as many continuous panels in the inner section as compared to the outer section. Bands are connected to the lower lateral margin of the main canopy. The pilot chute is connected to the main chute by spaced, individual suspension lines which connect directly between the periphery of the pilot chute and the crown of the main canopy. The size of the pilot chute and the length of the suspension lines are coordinated so that the pilot chute is held near the top of the main canopy when the main canopy is fully deployed. The pilot chute will encase the main canopy and the suspension assembly when they are in a packed configuration. The suspension assembly includes a relatively elastic centerline which will part on excess loading. It also includes a riser which has a relatively elastic upper section and a strong abrasion resistant lower section.
