ABSTRACT:
An improved ram air canopy is disclosed having a top skin formed of a plurality of substantially rectangular top skin pieces. Each top skin piece has areas of reduced width at predetermined locations. The areas of reduced width result in a specific tension pattern of the top skin so as to reduce distortion. The increased tension pattern of the top skin better maintains the modeled desired airfoil shape of the canopy.
