Abstract
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.
