Description
Summary:In this article we present the results of simulation of the initial discharge ignition in electronic equipment of spacecrafts which may appear inside spacecraft electronic equipment on the example of the external lacquer dielectric coating slot-hole defect between conductors. We solved the plasma physics task by COMSOL Multiphysics with a parametric sweep for each potentially vulnerable area in order to obtain diagrams of critical parameters. The most dangerous and the least dangerous areas of critical parameters responsible for the possibility of primary discharge ignition in space conditions are obtained. The resulting set of critical parameters can be used for preliminary diagnostics and development of discharge-sustainable electronic systems of spacecrafts.
