The investigation of contamination influence of own outside atmosphere and plasma of the stationary plasma thrusters on "Express-AM" spacecraft

In this work is reviewed the contamination influence of the own outside atmosphere and plasma of the stationary plasma thrusters on the critical surface of «Express-AM» spacecraft. This work presented the results of numerical evaluations, brought to light the contributions in contamination of different contamination sources and mechanisms of mass transportation. Special attention is paid to the influence of the spacecraft layout on the degree of contamination influence of the own outside atmosphere and plasma of the stationary plasma thrusters. This work gives the recommendations on minimization of this influence by optimization of the spacecraft layout.
