Vacuum container used for space target optical characteristic test

Abstract

The invention discloses a vacuum container for testing optical properties of a space object, which is characterized in that the main body is a spherical tank, the spherical tank is assembled by spherical shell plates in a partition manner and adopts football slice combination and orange slice combination; the top of the container is connected with a sun simulator, the side surface is provided withan access gate, the container is connected with a transmission light path device, and the container is provided with a plurality functional windows and can realize equidistant measurement of the external radiation measurement. Disclosed by the invention is a large-diameter spherical vacuum container with a diameter of 18m, and the vacuum container can bear the self-weight, the weight of internalheat sinks and the weight of other in-tank measurement and accessory equipment. The container not only satisfies the establishment of the space optical environment, the installation of the measurementequipment and the establishment of a space geometrical relation of full-size test pieces, but also ensures the operation rationality and the structural stability.

Description

technical field [0001] The invention relates to a large-scale vacuum low-temperature ring mold container in the field of space environment simulation, in particular to a vacuum container used for the optical characteristic test of a space object. Background technique [0002] In the optical characteristic simulation test of the space target on the ground, in order to simulate the vacuum and low temperature environment, a large vacuum container is required. In the test, the target needs to be observed from multiple angles, and the angle relationship corresponding to the measurement window should be specially designed, otherwise it will cause measurement errors; and the distance between the measuring equipment and the target should be kept consistent as far as possible, so as to obtain accurate radiation measurement results; And because the test environment requires vacuum, low temperature, and radiation, a lot of auxiliary equipment must be installed inside and outside to ens...
