HEAT INSULATION OF SPACE OBJECT POWER PLANT COMPONENTS AND METHOD OF ITS INSTALLATION Russian patent published in 2016 - IPC B64G1/58 

FIELD: engines.

SUBSTANCE: group of inventions relates to heat insulation of space object power plant components (SO PP). Heat insulation of SO PP components comprises a heat insulation of screen vacuum thermal insulation (SVTI) packages of the cryogenic tank and the cryogenic tank containment over them from a soft non-metallic material. Onto the cryogenic tank there is a cryogenic component supply unit - a flow control valve and a booster turbopump subunit with a pump and a turbine operating from the supply of hot gas from the gas duct behind the gas generator of the PP cruise engine. Heat insulation of the components (of the SO PP) includes heat insulation of the cryogenic component supply unit. Heat insulation of the cryogenic component supply unit consists of a heat-insulating material, the SVTI packages arranged over it and the cryogenic component supply unit containment over it arranged with a clearance relative to the SVTI.

EFFECT: technical result of the inventions group is reduction of losses of the cryogenic component by reducing the level of heat flow entering the cryogenic tank.
