Abstract: A deployable solar panel assembly including a housing, a solar panel receivable in the housing, and first and second support structures disposed on the housing proximate the lateral edges of the solar panel. The first and second support structures each include an extension member connected to the housing and a pair of tethering members pivotably connected to the housing on opposite sides of the housing. The pair of tethering members are foldable against the housing and, upon deployment, a distal end of each tethering member projects outward from the opposite sides of the housing. The distal end of a deployed solar panel is supported in an extended position by the extension member, and supported against displacement out of the plane of the panel by tethers connected to the distal ends of the pair of tethering members. Spacecraft employing the deployable solar panel assembly and methods of deploying the assembly are also disclosed.

Abstract: A method and apparatus for applying heat sufficient to permit plastic deformation of intermetallic material. The heat is applied to a fractional region of a workpiece, and then manipulations capable of causing the workpiece to deform are applied using conventional sheet metal forming equipment. The invention utilizes elevated forming temperatures to heat the fractional region of the intermetallic workpiece so that the fractional region has sufficient ductility to permit a plastic deformation required for the forming operation. The apparatus is a sheet metal-working machine which has been modified to provide the localized heating required to carry out the process of the present invention.
