Abstract
A self-inflatable parawing comprises an airfoil made of a flexible sheet erial and having a plurality of apertures located in the lower, aft surface thereof for admitting inflating air created by the positive air pressure of the air stream flowing over the airfoil. An inflatable support frame is located in the airfoil for providing spanwise stiffness to the airfoil. The support frame is inflated by means of a compressed gas cannister connected through a controllable valve to the support frame.
