FOLDING PARABOLIC REFLECTOR Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: two ribs 2 are attached to central support panel 1, which ribs are made in form of hinge parallelogram mechanism. Each rib is formed by two carrier rods 5 and 6, disposed in parallel, and posts 7. Each rib is connected by hinge one its rod with central support panel, and the other guide rod 6 is connected with shaft of electric engine by means of gear transmission. Parabolic ribs are mounted onto radial ribs 2, which are described according to parabola with the same parameter. When reflector is folded, rods 5 and 6 with parabolic ribs 12 and flexible reflecting envelope are assembled in two planes. EFFECT: improved precision. 1 dwg
