METHOD OF ENSURING THERMAL CONDITIONS FOR RETRANSMITTER Russian patent published in 2002 - IPC

Abstract RU 2193993 C2

FIELD: space engineering; methods of ensuring thermal conditions for communication satellite retransmitter. SUBSTANCE: method includes pumping liquid heat-transfer agent by means of electric pumping unit through hydraulic passage at required flow rate and temperature at presence of pressure of gas in gas chamber of heat-transfer agent accumulator. Prior to pumping the heat- transfer agent, difference of altitudes relative to Earth surface between levels of heat-transfer agent in hydraulic passage and in accumulator is measured and required pressure of gas is set in gas chamber of accumulator. EFFECT: enhanced reliability; avoidance of hidden defects in manufacture. 3 dwg
