Résumé
The LMGC team SIGECO creates and realizes innovative structures for space application in collaboration with CNES. The storage of elastic energy in flexible joints gives to these structures the advantage of being self-deployable [1]. A new concept of space reflector antennas using a deployable polygonal ring and civil engineering concepts has been recently developed [2]. A concept for CubeSats with a stowed size from 1U to 3U will be presented.
