METHOD OF CONTROL OF TEMPERATURE OF SPACECRAFT RADIATION SURFACES Russian patent published in 2005 - IPC

FIELD: spacecraft temperature control systems.

SUBSTANCE: proposed method includes measurement of temperature in areas of radiation surfaces of temperature control system, comparison of these temperatures with upper and low limiting magnitudes and delivery of heat to radiation surface when temperatures are below low magnitudes. Flight intervals at power requirement exceeding power generated by primary onboard power sources are determined. Amount of electric power consumed for temperature control of radiation surfaces is determined at the same intervals. Flight intervals for maximum possible accumulation of thermal energy on radiation surface in said zones within permissible temperatures are also determined. Expenses for radiation surface temperature control is taken into account. Before beginning of flight intervals at consumed electric power exceeding electric power generated by onboard power sources, heat is delivered to radiation surface zones which require consumption of power for their temperature control at these intervals. Delivery of heat is performed with upper limiting magnitudes of temperatures taken into account.

EFFECT: reduced loading of spacecraft power supply system due to reduced power requirement for radiation surface temperature control at retained preset temperature ranges on these surfaces.
