Abstract: A variable attenuation support system for a payload. A base support and a payload support are separated. A plurality of mounting pads are affixed to the base support, one such pad substantially at each corner of a first imaginary shaped plane. A plurality of mounting pads are affixed to the payload support, one such pad substantially at each corner of a second imaginary shaped plane which is similar in shape to, but larger than, and parallel to, the first plane. The planes are spaced apart and are relatively centered with corresponding sides parallel. A pair of pads are formed at each of the corresponding corners of the planes. An adjustable shock mount is provided for each of the pairs of pads. Each adjustable shock mount comprises a plurality of separable resilient shock absorbers, means for connecting a first one of the shock absorbers between the corresponding pair of pads, and means for releasably locking at least a second one of the shock absorbers in between the corresponding pair of pads.

Abstract: The shelter is constructed of composite, multilayer panels comprising an exterior skin aluminum sheet layer, a polymer composition foam layer, a divider skin aluminum sheet layer, an aluminum honeycomb layer, and an interior skin aluminum sheet layer. The five layers are bonded together to form the panel. In accordance with one aspect of the invention, the polymer composition foam layer has a scored surface to increase adhesive area and to increase the length of the shear failure line. In another aspect of the invention, the panels are closed out at at least two edges thereof with an extruded polymer-fiberglass closeout bar which is positioned between the inner and outer panel skins at the edge thereof and bonded thereto. These closeout bars are configured for rigid attachment between adjacent panels.
