EN The properties of an argon D.C. arc-jet functioning at low electric power (up to 4 kW) and mass flow rate 1.3 g/s are determined. The physical description of the arc takes into account two kinetic temperatures (Te,T) and non equilibrium condition for the ionization. The plasma properties as velocity, pressure, electron and heavy particles temperatures and densities are calculated by a Navier-Stokes modeling for stationary and axisymmetric conditions in the cylindrical throat and in the divergent part of the nozzle.
