Abstract
1. Неосевой имитатор солнечного излучения тепловакуумной камеры, содержащий входной иллюминатор, герметично встроенный в корпус тепловакуумной камеры, параболический коллимирующий отражатель для отражения имитируемого солнечного излучения на объект испытаний, расположенный в тепловакуумной камере, лампы - источники солнечного излучения, расположенные вне тепловакуумной камеры, отличающийся тем, что иллюминатор выполнен в виде двояковогнутой линзы, в качестве источников солнечного излучения взяты лампы с эллипсоидными рефлекторами и вспомогательными сферическими зеркалами для возврата на рефлектор части излучения, не попавшей на его поверхность, между параболическим коллимирующим отражателем и двояковогнутой линзой на пути светового потока установлен зеркальный смеситель, выполненный в виде равномерно расположенных в плоскости соприкасающихся своими гранями выпуклых зеркальных линз с квадратными профилями для отражения, перемешивания и увеличения светового потока до размеров параболического коллимирующего отражателя. ! 2. Устройство по п.1, отличающееся тем, что при применении его для имитации солнечного излучения на крупногабаритный объект испытаний, например космический аппарат, его оптические элементы выполнены с параметрами: ! - наружный и внутренний радиусы кривизны двояковогнутой линзы равны соответственно минус 1,050 и плюс 1,050 м; ! - диаметр двояковогнутой линзы равен 0,6 м; ! - половина угла сходимости потока, поступающего на двояковогнутую линзу (угол падения «крайнего луча» потока), равна 14°; ! - габариты выпуклых зеркальных линз с квадратными профилями равны 0,04×0,04 м и радиусы их кривиз 1. Non-axis simulator of solar radiation of a vacuum chamber, containing an input porthole, hermetically integrated into the housing of a vacuum chamber, a parabolic collimating reflector to reflect the simulated solar radiation on the test object located in a thermal vacuum chamber, lamps - sources of solar radiation located outside the thermal vacuum chamber, characterized in that the porthole is made in the form of a biconcave lens, lamps with ellipsoid reflectors are taken as sources of solar radiation and auxiliary spherical mirrors for returning to the reflector part of the radiation that did not fall on its surface, between the parabolic collimating reflector and the biconcave lens in the path of the light flux, there is a mirror mixer made in the form of convex mirror lenses with square profiles that are evenly touching their faces with square profiles to reflect mixing and increasing the luminous flux to the size of a parabolic collimating reflector. ! 2. The device according to claim 1, characterized in that when it is used to simulate solar radiation on a large-sized test object, for example a spacecraft, its optical elements are made with the parameters:! - the outer and inner radii of curvature of the biconcave lens are respectively minus 1,050 and plus 1,050 m; ! - the diameter of the biconcave lens is 0.6 m; ! - half the angle of convergence of the stream entering the biconcave lens (angle of incidence of the "extreme beam" of the stream) is equal to 14 °; ! - the dimensions of convex mirror lenses with square profiles are 0.04 × 0.04 m and the radii of their curvature
