Abstract: A system for a movable protective cover for buildings during severe weather. The system includes a base disposed beneath the surface of the ground; at least one structural support member movably coupled to the base and concealable within the base; a cover coupled to the at least one structural support member; and the at least one structural support member and the cover being moveable from a first position beneath the surface of the ground to a second position above the ground.

Abstract: A cryogenic fuel tank adapted for attachment to an aerospace vehicle includes an exterior layer of reinforced composite insulating foam. The insulating foam is reinforced with an aramid fiber mesh or a closed cell foam may be reinforced with one or more of carbon nanotubes, graphite whiskers, silicon carbide fibers or graphite fibers. The improved composite insulating structure disclosed herein provides a remedy for insulating material breaking off the large external fuel tank attached to the space shuttle during launch and ascent into space.

Abstract: An aircraft body structure is disclosed and has a skeleton frame including a plurality of interconnected frame elements. A skin layer is affixed to at least a portion of the frame elements. The skin layer has an exterior surface and an opposite interior surface. A composite reinforcing layer is affixed to at least a substantial portion of the interior surface of the skin layer. The composite reinforcing layer has a reinforcing material combined with a non-flammable polymer foam material in a variety of different manners.
