Abstract: A space antenna 20 may include an extendible boom 26 movable between stored and deployed positions. An extendible hoop 30 may surround the extendible boom 26 and is movable between the stored and deployed positions. A front cord arrangement 32 may be coupled to the extendible hoop 30 and defines a curved shape in the deployed position, and a reflective layer 36 may be carried thereby. A rear cord arrangement 40 may be behind the front cord arrangement 32 and coupled between the extendible hoop 30 and the extendible boom 26. The rear cord arrangement 40 may include a rear plurality of interconnected cords 42 defining rear polygons 44. Tie cords 42 may extend between the front cord arrangement 32 and the rear cord arrangement 40. A top cord arrangement 48 may be above the reflective layer 36 and coupled between the hoop 30 and the extendible boom 26.

Abstract: Systems and methods for operating a deployable reflector system. The methods comprising: causing a proximal end of a first link element (LE) located at a first end of a scissoring rib assembly (SRA) to slidingly engage a hub; allowing a proximal end of a second LE of SRA to pivot relative to the hub so as to cause scissor motion of SRA while the first LE is slidingly engaging the hub; causing a distal end of a third LE located at a second end of SRA to pivot relative to the edge member during the scissor motion of SA; allowing the edge member to slidingly engage a fourth LE located at the second end of SRA during pivotal motion of the third LE; and using the edge member to cause vertical movement of a peripheral edge of a reflector relative to the hub while the edge member slidingly engages the fourth LE.
