Nowadays, much attention is paid to research in the field of internal electrification of spacecraft (ES). It was shown that the ability of dielectrics to prevent the occurrences of electrostatic discharges (ESD) is determined by their conductivity, which is vary greatly during ground tests and under the influence of space factors. In this article, an ...

The paper presents the results of air
penetration strength experimental studies for a
two-electrode system consisting of a small radius and
plane hemispheres as the method of technical equipment
testing for determining their resistance to electrostatic
discharges. The hemisphere radius is much smaller than
the distance between the electrodes, so the mathematical
expression is used since the 50s of the last for ...

Abstract—We have simulated an electron bulk charging of the plastic cases of electronic devices as an integral part of the spacecraft internal charging problem. The semiconductor crystal has been placed inside a spherical shell of a polymer dielectric 10^−3–10^−2 m thick having an intrinsic (dark) conductivity in the range from 10^−16 to 10^−9 Ohm
^−1 ·m^−1. The crystal itself is a parallelepiped ...

Influence of electric field of charged spacecraft on secondary emission currents on the spacecraft surface is analyzed in terms of computation of secondary electron trajectories. Dependencies of the recollected electrons number on the electric field intensity at various distances from the emission point for standard secondary electron spectra are calculated. Criteria of the secondary electron ...

This paper describes modeling of spacecraft charging dynamics which is used in COULOMB-2 code in the case of spacecraft surface complex shape. The modeling of spacecraft charging is carried out via numerically solving the system of differential equations for time variations of local electric charge on every discrete element of the spacecraft surface. The presented ...

In the paper, we discuss numerical modeling of spacecraft charging in geosynchronous orbit which was done using Coulomb-2, NASCAP-2K and SPIS codes, and present data obtained using the MUSCAT code too. The main distinctive features of the codes above are specified, description of the Coulomb-2 code is given in more details. We compare the results ...
