发明名称 SEGMENTED STRUCTURE, IN PARTICULAR FOR A SATELLITE ANTENNA REFLECTOR, PROVIDED WITH AT LEAST ONE ROTATIONAL AND TRANSLATIONAL DEPLOYMENT DEVICE
摘要 A segmented structure includes at least two panels, wherein a first panel is referred to as main panel, and a second panel is referred to as secondary panel. The structure also includes at least one deployment device having a connecting arm secured to the rear face of the secondary panel and connected to the rear face of the main panel. The deployment device includes a movement system with a rotation unit that generates a rotation of the connecting arm about a reference axis, and a translation unit that generates a movement of the connecting arm in translation along this reference axis, so as bring the secondary panel into a stowed position or into a deployed position.

主权项 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 suitable for bringing said secondary panel into one or 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, said deployment device comprising: a link arm which is rigidly connected, by a first of the ends thereof, to the rear face of the secondary panel and which is connected, by a second of the ends thereof, to the rear face of the main panel by means of a structural portion; anda movement system arranged in said structural portion and comprising at least:a rotation unit suitable for rotating said link arm about an axis referred to as a reference axis, said link arm being arranged such that a rotation of said rotation unit allows said secondary panel to be brought directly into one or the other of a first position and a second position relative to said main panel, said first position and said second position being respectively located, in a lateral plane, substantially in said storage position and in a position associated with the deployed position; anda translation unit suitable for translating said link arm along said reference axis so as to move said secondary panel relative to said main panel in a direction that is transverse to said lateral plane, wherein the movement system is configured to carry out successive translation and rotation movements, respectively implemented by the translation unit and by the rotation unit.
