FIELD: testing equipment.
SUBSTANCE: invention is related to the sphere of space engineering. Device for thermal-vacuum tests contains fixed cylindrical cryogenic screen installed in the vacuum chamber, spatially positioned screen with size changing bracket, and drive of 3D dislocation. Method of thermal-vacuum tests is characterized by presence of the remotely moved spatially positioned screen with spatially changed form geometry. The spatially positioned screen ensures variational, differentiated cryostatting of some elements and assemblies of the space vehicle.
EFFECT: increased speed of the test unit setting to the mode, achievement of the lower temperatures for local areas of the tested vehicle.
