Modeling of the Spacecraft Charging of Complicated Configuration

One of the most important factors affecting the spacecraft (spacecraft) and the cause of the defiantly failing equipment is the electrification process. The consequence of electrification is the occurrence of electrical discharges on the apparatus. Differential charging increases this danger. At the moment, there are four programs in the world that allow simulating the electrification of a real spacecraft. I conducted simulation of electrification with the help of the Russian COLOUMB. In this paper, I presented the results of the simulation using light code. In which the potential distributions on the surface of the spacecraft and the potential isolines reflecting the configuration of the electric field in the spacecraft space are shown. The performed calculations showed that even relatively simple geometric models demonstrate differential charging of space vehicles.
