Abstract
A solar cell array deployable from a folded flat triangular structure to a substantially circular deployed shape. A root spar supports a hub. The hub has an axis of rotation normal to the axis of the root spar. The hub drives a lead spar, and a plurality of intermediate spars rotate freely around the hub. A foldable gore is fitted between each pair of adjacent spars except between the root spar and the lead spar. Rotation of the hub in one direction folds the gores into a stack. Rotation in the opposite direction opens the gores to form tensioned membranes between the spars. A reversible power source drives the hub.
