Abstract:
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.
