ABSTRACT:
An improved cruciform-type parachute is provided for aerial delivery of cargo, with a center panel shaped as a square or other regular polygon, and first lens-shaped panels conjoined to each edge of the center panel. The first lens-shaped panels are formed of two circular section sub-panels conjoined along their respective arc segments. Side panels, shaped as rectangles or other quadrilaterals, have one edge conjoined with each first lens-shaped panel at the other edge opposite from the center panel. The adjacent side edges of each pair of adjacent side panels are conjoined to either convex edge of a second lens-shaped panel. The second lens-shaped panels are defined by three edges; two of which are defined by symmetrically opposed convex arcs joined at one end, and the third edge defined by a straight line intersecting the other ends of the arcs. One end of each of a plurality of upper rigging members are disposed along an edge opposite from the first lens-shaped panel on each side panel. The other ends of the upper rigging members converge and conjoin with an upper end of a single lower rigging member. The lower end of each lower rigging member connects to the supported cargo. Additional lens-shaped panels may be disposed between lateral divisions of the side panels.
