LARGE APERTURE UNFURLABLE REFLECTOR DEPLOYED BY A TELESCOPIC BOOM

摘要

A boom and reflector assembly for a spacecraft including a telescopic boom having a plurality of tubular sections that are nested together within a base section when the boom is in a stowed position, where the base section is mounted to a stowing cradle within the spacecraft by a root hinge. The assembly also includes a reflector having an outer truss structure including truss rods that are collapsible to allow the reflector to be collapsed into a stowed configuration, where the reflector is mounted to an outer one of the tubular sections having a smallest diameter by a wrist hinge. The assembly is configured to be released by the root hinge to rotate the boom and the reflector, rotate the collapsed reflector on the wrist hinge, deploy the reflector from the collapsed configuration to a deployed configuration, and then extend the boom to move the reflector away from the spacecraft.
