FAMILY OF DEPLOYABLE RETRACTABLE STRUCTURES FOR SPACE APPLICATION

New trends in the frame of space applications lead to the necessity of using deployable/retractable structures, working either as beams (wit h payloads all along their length) or masts (loaded at their tip). SEN ER-under ESA/ESTEC and Spanish Space Program contracts-are developing a family of structures with deployment and retraction capabilities (LT S, SENERMAST, CTM) so as to cover all ranges of potential necessities in the space community (antennas, experiment support, solar arrays, he at rejection systems...). This paper consists of a summary of the perf ormances and range of applications of LTS, SENERMAST and CTM, and pays special attention to the large truss structure (LTS) development and verification.
