DEVICE TO PROVIDE CRYOGENIC CONTAINER THERMAL CONDITIONS IN OPERATION OF SPACE OBJECTS Russian patent published in 2011 - IPC B64G1/58 F16L59/06 

FIELD: transport.

SUBSTANCE: invention relates thermal insulation of, primarily, cryogenic containers of space objects. Device provide thermal conditions for cryogenic container 1 and comprises vacuum-shield heat insulation 2, pressure shell 3 covering heat insulation 2 and safety valves 6 communicated with space between container 1 and pressure shell 3. Valve 6 serve to prevent destruction of pressure shell by inner pressure. Pressure shell 3 is made from soft non-metal material rested on heat insulation 2 with the help of regularly spaced non-metal bosses 4. Thus, space 5 is produced between container 1 and pressure shell 3. Pyro valves 7 open said space on initial trajectory of placing the space object on orbit. Drain valves 8 open at atmospheric pressure drop to communicate space 5 with ambient atmosphere. As a result, gas flows out from space 5 till complete evacuation of heat insulation 2.

EFFECT: reduced losses of cryogenic component in long-term operation of space objects and reduced weight of space object.
