SYSTEM OF SPACECRAFT THERMAL PROTECTION Russian patent published in 2009 - IPC B64G1/22 B64G1/58 

Abstract RU 2360849 C2

FIELD: transportation; heating.

SUBSTANCE: system of spacecraft thermal protection comprises screen-vacuum heat insulation (SVHI). For SVHI device is arranged to provide for its strength and thermal characteristics in the form of through drain holes that are evenly installed along insulation surface. Heat-reflecting screens are installed above drain holes with clearances relative to SVHI. Drain holes communicate interlayer volumes of insulation and volume of gas medium under SVHI between each other and to environment. Total efficient areas of drain holes in SVHI and gaps between it and screens are defined with account of total volume of gas medium in interlayer volumes of insulation and underneath. At that gas medium pressure drop that is maximum in trajectory of carrier rocket flight and affects SVHI is also taken into account.

EFFECT: preserved strength of heat protection and its thermal characteristics during spacecraft bringing to space by carrier rocket, increased reliability of board systems and device units operation.
