Abstract:
A method of mathematical modeling of the impact of the erosion from plasma jets of electric rocket engines (ERE) on netblade of ref-lectors of large antennas of unmanned spacecraft (SC) is described. The results of numerical evaluation confirming its effectiveness are given. The expression to evaluate the degradation of co-reflection coefficient of netblade of reflectors of large antennas is obtained from laboratory experimental studies. Results of calculations of degradation of the reflection coefficient of the netblade of reflectors of large antennas of advanced unmanned spacecraft developed at JSC Academician M.F. Reshetnev «Information Satellite Systems» are given.
