Abstract
A reflector assembly includes a frame centered about a longitudinal axis and having a first height along the axis. A curved body extends from the frame and has a second height along the longitudinal axis could be greater than the first height. A stretchable membrane has an electromagnetically reflective surface and is secured to the curved body.
Claims25
A reflector assembly comprising:
- a frame centered about a longitudinal axis and extending a first distance along the axis the frame including a plurality of longerons and struts that are pivotable relative to one another such that the frame is moveable between a deployed condition and a collapsed condition;
- a curved first body secured to the frame and extending a second distance along the longitudinal axis greater than the first distance;
- and
- a reflective mesh having an electromagnetically reflective surface and being secured to the curved first body.
