Abstract:
To ensure the equipment of aircraft works stably and reliably during extravehicular activities,the equipment exposed to vacuum requires appropriate thermal control measures.Aiming at the overall structure and thermal design of aircraft,passive thermal control measures are used to regulate the temperature of the equipment outside the aircraft.The surface temperature of the equipment under different structural and environmental conditions is calculated by simulation using thermal analysis software Thermal-Desktop,the corresponding thermal control effect is analyzed in detail,and the optimal thermal design scheme is proposed.Based on the simulation calculation,the partial passive thermal design scheme has been tested and verified through the thermal vacuum experiment.The test results show that the bottom plate of backpack is used as an isothermal radiator,the equipment mounting surface is completely in contact with the bottom plate and the thermal grease is filled between them,the maximum temperature on the equipment surface is lower than 40℃,the thermal control can provide well temperature control for the equipment.
