Abstract: A large, deployable reflector (10) having several long, tapered petals (20) hinged at the tapered end to a top ring. The top ring (22) is attached to a central disk (26) positioned below the top ring (22) such that it is contained within the petals (20) when they are in the closed position. The center disk (26) is attached to the top ring (22) by several screw jacks (28) such that the center disk (26) moves up to a position proximate the 10 top ring (22) as the petals (20) are moved outward from the closed position to the open position. In the deployed position, the reflector surface forms a substantially solid, parabolic surface. Telescoping struts (40) are attached to the underside of selected ones of the petals (20) to enable steering of the reflector (10). The struts (40) are positioned such that the central axis of the paraboloid formed by the deployed reflector (10) remains clear.
