  • Deployable membrane shell reflector
    Patent number: 4926181
    Abstract: A stowable reflector assembly includes a flexible reflector shell that is rolled into an essentially cylindrical shape and retained by remotely controlled clamps. An underlying folding structure is deployed by remote signal and forms an underlying structure upon which the flexible reflector unrolls. Magnetic strips and auxiliary retaining mechanisms align and retain the reflector on the underlying support and urge it to a position from which it can accurately reflect electromagnetic radiation.
