STAND FOR THERMAL VACUUM TESTING OF SPACECRAFT ELEMENTS Russian patent published in 2021 - IPC B64G7/00 

FIELD: space technology.

SUBSTANCE: invention relates to the testing of elements of spacecraft (SC) with simulation of the conditions of outer space. The stand contains a vacuum chamber (VC) with its vacuuming system (VS), a cryogenic screen located along the internal contour of the VC, a simulator of external heat flows, a test process control system. The stand is equipped with a loading lid with sealing gaskets placed between its flange and the flange of the VC housing, forming a vacuum cavity. The lid is equipped with a lifting and lowering mechanism with a table suspended from it, on which a spacecraft element connected to the functioning system is installed. There is a heating system for the VC and the operating bodies of the VS in the form of cable heaters with thermocouples, heat-insulating covers for the shelter of all heating units, a pneumatic system for controlling the operating bodies of the VS and its cooling, a heating system and one for compressed air supply to the cryogenic screen.

EFFECT: increase in the reliability of tests and confirmation of the operability of individual elements of the spacecraft, mainly in conditions of ultra-high vacuum.
