月面外热流分析是月面航天器热控设计的前提,而月面红外辐射是月面外热流的重要组成部分.就目前研究而言,月面辐射外热流计算所采用的几何模型及光学参数并不相同,计算结果相差较大.本文针对有限面积的月面几何模型及采用漫射体假设的辐射参数模型开展误差分析,旨在提高月面红外辐射外热流计算精度.笔者依据热辐射原理及月面环境特点建立了月面红外辐射外热流模型,面对具体案例,利用理论计算及仿真分析进行求解,最后针对有限面积及漫射体假设两种影响因素开展误差分析,分析结果能够为月面外热流计算提供依据.
Error analysis of infrared radiation heat flux calculation on the lunar surface based on the assumption of limited area and diffusion object
Analysis of lunar heat flux is a prerequisite for thermal control design of lunar spacecraft,and lunar infrared radiation is an important component of lunar heat flow.As far as current research is concerned,the geometric models and optical parameters used for calculating the heat flux of lunar radiation are not the same,resulting in significant differences in the calculation results.This article conducts error analysis on the geometric model of the lunar surface with limited area and the radiation parameter model using the assumption of diffusion object,aiming to improve the accuracy of infrared radiation heat flux calculation on the lunar surface.This article establishes a lunar infrared radiation heat flow model based on the principle of thermal radiation and the characteristics of the lunar environment.Using theoretical calculations and simulation analysis to solve specific cases.Finally,error analysis was conducted on the factors of limited area and diffusion object assumption,and the analysis results provided a basis for the calculation of heat flux on the lunar surface.
