  • Patent number: 11444571
    Abstract: A solar array may include a first rigid composite solar panel including solar cells secured to a first substrate. The solar array may further include a second rigid composite solar panel including solar cells secured to a second substrate. The solar array may also include solar panel modules including solar cells secured to a flexible sheet of material. The solar panel modules may be coupled between the first composite solar panel and the second composite solar panel. The solar array may be configured to be retained in a stowed arrangement with the solar panel modules between the first rigid composite solar panel and the second rigid composite solar panel. The solar array further configured to be extended with an extendable arm until each of the first rigid composite solar panel, the second rigid composite solar panel and the solar panel modules are arranged in a substantially straight line.
    Type: Grant

  • Patent number: 8006462
    Abstract: A deployable truss is formed from a plurality of column members connected at their ends where at least some of the column members are formed from column assemblies, each including a plurality of strut members that are at least connected to each other at a first and second end of the column assembly. For added rigidity, strut members of a column assembly may be connected to each other between the first and second ends using, for example, a rigidizable resin, a fixed spacer, or a deployable spacer. Connecting strut members between the ends of the column assembly provides mutual bracing to the strut members and decreases the free buckling length of the individual strut members. Spacers are preferably configured to radially space the strut members away from the longitudinal centerline of the column assembly to increase its moment of inertia, and hence its buckling strength.
