The research of the erosive impact by the stationary plasma engine jets on the radio-reflective net of the space craft large-sized antennas

The erosive aspect of the stationary plasma thrusters (SPT) jets on the radio-reflective net of the space craft large-sized antennas is reviewed in the report. The approach of the theoretical estimation of the large-sized antenna radio-reflective net resource on the base of «relative value of the covering erosion» parameter is proposed in the report. The experiments on the definition of the dispersion coefficient of the gold coating of the large-sized antennas radio-reflective net and reflectance degradation depending on the size of the covering erosion are described in this report.
