Abstract: A solar array including a solar array assembly, hub assembly, and wing assembly.

Abstract: A long, elastically deployable tubular boom structure consisting of two or more thin-walled booms with a continuous longitudinal slit-opening along its entire length on the backside and a composite reinforced or metallic construction. The slit-opening, thin-walled tubular section accompanied by the boom elastic properties and unique fastening method between the boom segments allows the segmented boom to be flattened and then rolled up into an extremely compact cylindrical stowage volume. The boom elastically and immediately deploys from a rolled stowed configuration under its own strain energy without use of a motor or other complicated actuators/mechanisms. The segmented construction of multiple tube elements allows for unlimited boom lengths and enables unlimited structure scaling.

Abstract: A module for forming part of an articulated mast which can be retracted to be stowed and elongated to be deployed, the mast when deployed having a central axis of elongation and a plurality of these modules. Each module has at least three rigid non-folding station rods joined to form a rigid station, and an equal number of non-folding longerons, each hingedly connected to a corner of the station. Four diagonal segments are formed as part of two flexible inelastic cables, which are brought together at a control which always holds one of the cables, and passes the other. The control includes a releasable catch to hold the other cable when its segments are at lengths respective to a deployed module.
