| Abstract: | In order to improve the adaptability of spacecraftthermal control system, this paper investigates the thermal control scheme ofthe deployable radiator coupled with a liquid loop. The thermal environmentchanges of the radiator at different orbit altitudes are analyzed. The thermalcontrol characteristics of the fixed radiator and the deployable radiator indifferent orbit environments are compared. The results show that as thedeployment angle of the radiator changes, the space heat flux absorbed by theradiator also changes, which directly affects the heat dissipation capacity ofthe thermal control system. The deployable radiator can enhance its ability ofheat dissipation. In engineering applications, based on the thermal controlliquid loop, by adjusting the deployment angle of the deployable radiator, thethermal adaptability of the spacecraft can be effectively improved. |
