Abstract
The openings in the fabric ribs of a deployable wing made from fabric sail material is automatically closed by use of a zipper mounted adjacent each of the openings that is actuated by movement of the cross spars of the deployable wing which serves to prevent the airfoil surface to the wing to bulge and cause a drag to the deployable wing when in flight.
