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.

Student Theses at HSE must be completed in accordance with the University Rules and regulations specified by each educational programme.

Summaries of all theses must be published and made freely available on the HSE website.

The full text of a thesis can be published in open access on the HSE website only if the authoring student (copyright holder) agrees, or, if the thesis was written by a team of students, if all the co-authors (copyright holders) agree. After a thesis is published on the HSE website, it obtains the status of an online publication.

Student theses are objects of copyright and their use is subject to limitations in accordance with the Russian Federation’s law on intellectual property.

In the event that a thesis is quoted or otherwise used, reference to the author’s name and the source of quotation is required.
