Postfabrication adjustment of contour of panels for reflector, such as parabolic reflector for radio antennas, possible with simple mechanism consisting of threaded stud, two nuts, and flexure. Contours adjusted manually.
Parabolic reflector 80 feet in diameter stowed in space of only 36.5 feet long and 14.5 feet in diameter with new folding scheme. Upon command, stowed reflector is automatically deployed to full size. Petallike panels unfold from central fixed section to create inner reflector dish. Reflector is composed of rigid panels. Number of panels depend on reflector size when deployed and upon required package size when stowed.
The maximum deployed diameter stowable in shuttle was determined for the original concept and for new more efficient concepts. Estimates of weight, surface accuracy and cost were made for the various configurations. Five critical technologies were identified which would be required to manufacture large solid deployable reflectors. These technologies are concerned with surface accuracy improvement and verification.
