A canopy-type parachute is provided which includes improved stability features and lends itself to relatively easy assembly. Integral valves promote stability of the airfoil by not allowing rapid deflation of the airfoil, and their location and orientation within the airfoil promote structural rigidly of the overall airfoil, even out to the front top edge of the airfoil. The valves in one configuration bias against a vertical, loaded rib which tends to provide a consistent taut and planar surface for the valves to bias and act against.

[ What is claimed is:] [1.] An airfoil, said airfoil comprising:an upper layer;a lower layer;a plurality of substantially vertical rib panels interconnecting said upper and lower layer and defining at least one air channel for receiving air therein; andat least one valve panel portion, said valve panel portion having a free valving edge portion configured for bias against one of said vertical rib panel, but said free valving edge portion still being detached from said one of said vertical rib panels to allow said air to pass between said one of said vertical rib panels and said valving edge portion.
