Abstract

The structure of a plasma stream effusing of a nozzle of the electro-jet drive in vacuum, by the solution of combined equations of Vlasova-Puassona is viewed, distribution functions of charged particles, velocities, concentration and the self-compounded electric fields in a plasma stream, depending on the characteristic parametres of a problem are gained: directional velocity on an edge of a nozzle, concentration, breadths, the relation of temperatures of ions and electrons.

Keywords:

a stream of rarefied plasma, a stationary plasma propulsion unit, the equations of Vlasova-Puassona, a method of large particles, a distribution function of charged particles.
