摘要
为全面分析绕月和月面探测器可能经历的热环境作为热控设计依据,文章给出了典型高度和β角的环月圆轨道中,绕月探测航天器接收的太阳和月球红外热流密度及其变化规律。针对复杂月表地形,提出并采用月面三维月壤热模型,计算给出了不同太阳高度角下月面探测器在常规平坦月表的外热流密度情况,定量研究了月面山丘高度及其与探测器距离对探测器表面接收红外热流的影响程度,定性分析了复杂月表地形和月尘对探测器表面红外热流的影响。
To analyze the thermal environmental profile for the lunar orbiters and the lunar rovers in the corresponding thermal design,the solar radiation and the lunar infrared heating of the spacecraft are calculated for the circumlunar orbit with typical altitudes and β angles.The curves of the heat variations are obtained.For the lunar rovers,a three-dimensional thermal model of the lunar surface is built with consideration of the complex landforms.The density of the external thermal flux on the lunar rover on a flat moon surface is calculated for different elevations of the sun.For vehicles in hilly regions,the exposed flux variations of the lunar infrared heating are quantified against the altitude to distance ratios of the massif.The contribution of the surface topography and the lunar dust to the thermal environment is also analyzed qualitatively.
