Abstract
Thermal characteristics research is an important and basic part of satellite thermal control system, properties of infrared radiation study, infrared stealth design. In this paper, a satellite orbit calculating model was established to get three-dimensional coordinates of satellite. Based on the relative position of sun, satellite and earth, the space heat flux of three axis stabilized satellite calculating model was established. Considering space heat flux, satellite radiate internal, heat load and other factors, the heat transfer analysis and calculation for satellite was made, and the temperature distribution of satellite at different times on different faces was obtained. Then, the effects of solar absorption coefficient and internal heat loading on the satellite surface temperature distribution were analyzed. The results showed that satellite surfaces tempera?ture were significantly lower in the shaded area of Earth. Except the cooling surface, solar absorption coefficient had great influence on satellite surface temperature. According to the cooling surface temperature, the status of satellite could be roughly judged关键词
