Quantitative analysis method for potential barrier between space plasma bodies and plasma bodies generated through electric propulsion

Abstract

The invention discloses a quantitative analysis method for potential barrier between space plasma bodies and plasma bodies generated through electric propulsion. The quantitative analysis method is applicable to the analysis of the action process of the space plasma bodies and the plasma bodies generated through the GEO orbit satellite electric propulsion. The diffusion process of the plasma bodies generated through the electric propulsion is compared with the diffusion process of current carriers in a semiconductor, and a diffusion model for the space plasma bodies and the plasma bodies generated through the electric propulsion is built according to the semiconductor current carrier diffusion theory; the quantitative expression relationship between the potential barrier intensity v between the space plasma bodies and the plasma bodies generated through the electric propulsion, and the parameters of space environment plasma bodies and the parameters of the plasma bodies generated through the electric propulsion is deduced by using the diffusion model; during the analysis, the parameters of the space plasma bodies of a GEO rail and the parameters of the plasma bodies generated through the electric propulsion are determined; according to the two kinds of determined plasma body parameters, the parameters are substituted into the quantitative expression relationship to determine the potential barrier intensity between the space plasma bodies and the plasma bodies generated through the electric propulsion.
