segmented structure, particularly for satellite antenna reflector with deployment device combined rotation and translation

摘要

Segmented structure, in particular for Satellite Antenna reflector, the segmented structure (1) comprising: - at least two panels (2, 3, 4) intended to be deployed in Space,(2) comprising a first panel, a Front Face, a rear Face (2a) and (2b), and comprising a second panel (3, 4), also called Secondary, a Front Face (3a,4a) and a rear Face (3b,4b); and at least a deployment device (5) attached to the rear Faces of the main and Secondary panels respectively, and suitable for the side panel (3),4) to one or other of the following two positions in relation to the main panel (2): - a storage position (P1), in which the side panel (3),4) is at least partially superimposed on the main panel (2) on the rear Face (2b), and the front Face (3a, 4a) of the side panel (3),4) directed in the same sense that the anterior side (2a) of the main panel (2); and a deployed position (P2), in which the side panel (3),4) is positioned at the outside of the main panel (2), alongside and against the main panel (2), in order to determine a continuous set at least in their faces,- including the deployment device (5) a system of spin (9) suitable to generate a Twist of the Transfer System (6) and the secondary panel (3),4) related to such Transfer System (6) with regard to the main panel (2),Understanding the system of spin (9) at least one Unit of spin (10) able to generate a spin (10) between a First Structure element (11) of the rear Face (2b) of the main panelIPAL (2) and a Second Structure element (12) which is connected with the Transfer System (6),Characterized by such deployment device (5) further includes a Transfer System (6) comprises at least one translation unit (7) provided with a Helical Motor Union (8)That is a Transfer System (6) connected with the side panel (3, 4) and Being suitable to generate a Translational Movement of the side panel (3),(4) with regard to the main panel (2).
