Abstract: A corrosion resistant coating to protect metallic and polymeric composite surfaces from corrosion and water promoted deterioration that is environmentally safe and non-toxic and is applied in one coat without the use of a primer is provided. The coating comprises a tough, flexible polyurethane binder and a corrosion inhibiting pigment selected from the group consisting of zinc hydroxy phosphite, zinc phosphate, calcium ion-exchanged silica, calcium strontium zinc phosphosilicate. The coating is effective in protecting both aluminum and steel surfaces against corrosion in salt spray environments and in protecting polymeric composite materials such as ablative coatings used in aerospace against deterioration after exposure to water.

Abstract: The deployable wing of the present invention comprises an internal structure having diverging leading edge spars attached to a keel spar and cross spars to form a delta wing configuration. This internal structure is enclosed within a volume defined by a fabric sail having an upper section and a lower section. This fabric sail volume is internally pressurized through a ram air intake at the nose stagnation point. This deployable wing can be folded closed, extracted from an aircraft, deployed in the air and landed with the aid of parachutes.
