Electrically powered ion acceleratot with contact ionixation for perspertive electrically powered thrusters

Abstract

A number of characteristics of ionic and ion-plasma accelerators laboratory samples designed for electrically powered spacecraft propulsion were investigated in the experimental research. In a large-sized vacuum chamber (2.4 m^3, 10^-3 Pa) in the MCA named after A.F. Mozhaysky provided the necessary physical and technological processes, methods and means of measurement, parameters and operation modes of ion accelerators with contact ionization were provided in a large-sized vacuum chamber (2.4 m3, 10-3 Pa) in A.F.Mozhaysky`s Military-Space Academy. The theoretical analysis, including by computer simulation, of samples design features, as well as physical processes and operating parameters was carried out. It is established that the implemented and tested measurement methods, technologies, and ion-physical laboratory samples characteristics correspond to the tasks of developing promising electrically powered spacecraft propulsion.
