Abstract
If the energy arrives at surface of space structure is well-proportioned in space, the heat flux of space structure would be equal to effective radiation area of space structure. Based on this theory, the problem how to calculate heat flux can be transformed into that to find effective radiation area of space structure. This paper develops a quick and high-fidelity blanking algorithm based on algorithms of Computer Graphics, to help in calculating effective radiation area of space structure. The presented algorithm is used to determine the effective projection of huge multibody satellite, as an example, and then gets the heat flux of satellite. The results obtained well agree with those by the thermal analysis software, and the movement of satellite in orbit can be showed.关键词
