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.
