  • Accurate lunar surface temperature distribution model is important for human lunar exploration. But there is a lack of research on how to calculate the temperature distribution of the entire lunar surface. In this paper, an entire lunar surface temperature model has been established which uses Racca model to calculate temperature of the lunar sunny side. For lunar shady side, the lunar surface is divided into several zones along the latitudinal direction whose temperature is solved by one-dimensional non-steady heat conduction equation. According to Chang'E-3 solar array temperature data, parameter values of the heat conduction equation are amended. Thermal analysis results of Chang'E-3 solar array temperature are in good agreement with the measuring data, which preliminary proves that this model is sound and feasible. Based on lunar temperature distribution calculated by this model, heat flux characteristic of the solar array on polar lunar orbit has been researched.
