摘要
对月面热环境进行了调研,基于月球赤道附近着陆任务需求,对载人月球探测登月舱在月昼高温环境下的热排散方案进行了初步设计。热控系统通过冷板和换热器进行热量收集,基于流体回路进行热量传输,并以可展开式辐射器作为热量排散的主要手段,以水升华器进行热量排散的辅助手段;分析了月面月昼期间辐射器散热能力及水升华器辅助散热需求。最后,基于Python语言建立了热控系统仿真程序,对月昼期间热控系统运行性能进行了仿真分析。结果表明当辐射器面积为29 m^(2)时,热控系统可满足舱内外设备的控温要求;设置水升华器辅助散热,可以减小辐射器面积。
This paper investigates the thermal environment about Lunar surface.Based on the requirements of landing mission near the equator of the moon,the heat rejection scheme of the Manned Lunar Lander Module was designed under the high temperature environment during the moon day.The Lunar Lander thermal control system(TCS)accomplished the heat acquisition function using various coldplates and heat exchangers,and the heat transport function was accomplished using a double-loop system architecture.For the majority of the mission,heat rejection was accomplished using deployable radiator.A sublimator was chosen as the supplemental heat-rejection device.The instantaneous radiator heat rejection capability and heat rejection requirement by the sublimator during moon day was analyzed.The simulation program of TCS was established based on Python language,and the performance of the TCS during lunar day was simulated.The results show that when the radiator area is 29m^(2),the thermal control system can meet the temperature control requirements of the equipment inside and outside the cabin.Sublimator as a heat-rejection device can reduce the radiator area.
