1. Segmented structure, in particular for a satellite antenna reflector, said segmented structure comprising:
at least two panels, intended to be deployed in space, a first panel referred to as the main panel, comprising a front face and a rear face, and a second panel referred to as the secondary panel, also comprising a front face and a rear face; and at least one deployment device connected to the respective rear faces of said main and secondary panels and is configured to bring said secondary panel into one or the other of the following two positions, relative to said main panel;
a storage position, in which said secondary panel is positioned at least in part on said main panel on the rear face thereof, the front face of said secondary panel being directed in the same direction as the front face of said main panel; anda deployed position, in which said secondary panel is positioned towards the outside of the main panel, to the side and against said main panel in order to form a continuous assembly at least on the front faces thereof,wherein said deployment device comprises:a translation system comprising at least one translation unit provided with a helical geared motor, said translation system being connected to said secondary panel and being configured to generate a translational movement of said secondary panel relative to said main panel; anda rotation system configured to cause said translation system and the secondary panel connected to said translation system to rotate relative to said main panel, said rotation system comprising at least one rotation unit configured to generate a rotation between a first structural element rigidly connected to the rear face of the main panel and a second structural element, to which the translation system is connected. |
