Abstract
1. Складной параболический рефлектор, содержащий гибкие ребра жесткости, обтянутые сетеполотном, отличающийся тем, что, с целью повышения стабильности формы рефлектора в заданном диапазоне эксплуатации, ребра выполнены из материала с двойной термомеханической памятью формы.2. Способ изготовления складного параболического рефлектора по п.1, заключающийся в изготовлении ребер из материала с термомеханической памятью, придании им требуемого параболического профиля нагреванием до температуры запоминания «теплой формы», проявляющийся при максимальной температуре диапазона эксплуатации, отличающийся тем, что ребра фиксируют в кондукторе, изготовленном из материала с минимальным коэффициентом линейного расширения, и подвергают термоциклированию между крайними значениями температур диапазона эксплуатации рефлектора не менее 10 циклов до получения у них памяти «холодной формы».1. Foldable parabolic reflector containing flexible stiffeners fitted with a net-sheet, characterized in that, in order to improve the shape of the reflector in a given operating range, the ribs are made of a material with double thermomechanical shape memory. 2. A method of manufacturing a collapsible parabolic reflector according to claim 1, which consists in the manufacture of ribs from a material with thermomechanical memory, giving them the desired parabolic profile by heating to the memorization temperature "warm form", which manifests itself at the maximum temperature of the operating range, characterized in that the ribs are fixed in the conductor, made of a material with a minimum coefficient of linear expansion, and is subjected to thermal cycling between extreme temperatures of the operating range an inflector of at least 10 cycles until they receive a “cold form” memory.
