Abstract
A maneuverable, ram air inflated, flexible aerial wing includes a plurality of adjacent, forward facing air cells having first openings along the leading edge thereof and a control surface extending between the aforesaid cells and the trailing edge. Generally rectangular in overall shape the cells are of such size and so positioned, and include rearward facing second openings, as to displace the separation point of the relative airflow across the upper surface further toward the trailing edge than with known devices, and which therefore achieves a higher lift to drag ratio. Further, the control line system and a series of rear vents combine to reduce the force required to lower the surface and help prevent erratic flight.
