ADJUSTABLE BEAM REFLECTOR Russian patent published in 2002 - IPC

FIELD: space communications engineering. SUBSTANCE: mirror reflecting curtain is disposed on pneumatic frames being rolled up which carry magnetic films in the form of rings and/or electromagnets. As an alternative nonreflecting mirror curtain may be covered with isolated concentric rings of magnetic film whose magnetic field has alternately oriented lines of force in mutually opposite or parallel directions to odd- and even-numbered spiral electrical conductors connected to emf sources. EFFECT: reduced radius of curvature of spherical reflectors, ability of rolling up rectangular reflectors. 9 cl, 5 dwg
