ABSTRACT:
A RAM air inflatable gliding wing including a plurality of cells interconnected as by stitching along appropriate adjacent side edges thereof. Each of the cells is constructed utilizing an upper and lower flexible member secured together over the entire length thereof. Disposed span wise between and secured to the side edges of the upper and lower flexible members is reinforcing tape preferably carried by a plurality of sections of flexible material. The structure provides airfoil shaped tubes or cells which when in inflated profile is that of shark and cetacean design. An air intake is provided at the leading edge of each of the cells and is constructed including a non-return valve. The reinforcing tape provides a central load network system which provides reinforcement and serves to stabilize the canopy when fully deployed both span wise and chord-wise while at the same time attenuating stress and pressure on the lower surface of the parachute canopy during deceleration.
