20120167943 | Unwindable Flat Solar Generator - A solar generator deployment device includes an assembly comprising a plurality of tape-springs supporting a windable membrane on a face of which is arranged a plurality of elements capable of converting the solar energy into electrical energy. The tape-springs and membrane are co-wound around a unique radius of curvature equal to the natural radius of curvature of folding of the tape-spring in the wound state. The tape-springs are substantially parallel and interlinked by transversal braces ensuring the rigidity of the bearing structure. | 07-05-2012 |
20120167944 | Boxed Unwindable Solar Generator - A solar generator deployment device includes at least one primary tape-spring supporting a flexible membrane with a set of flexible photovoltaic cells on one face, at least one secondary tape-spring, and a reinforcing structure attached to the primary tape-spring and secondary tape-spring, said device having a wound state in which the primary tape-spring supporting the flexible membrane and secondary tape-spring and reinforcing structure are co-wound around a mandrel; and an unwound state in which said primary tape-spring and secondary tape-spring are unwound. The device comprises, at the level of said mandrel, means for offsetting, in the unwound state, the root of said secondary tape-spring so that the reinforcing structure is deployed within a volume situated on the side opposite the face of the flexible membrane comprising flexible photovoltaic cells and supports said flexible membrane, the device then being in the deployed state. | 07-05-2012 |
