Abstract The paper presents an engineering simplified mathematical model for estimating integral characteristics of radio-frequency ion thrusters with additional magnetostatic field. In addition to the calculation, proposed allows obtain distributions some plasma local parameters in a gas-discharge chamber thruster – atoms and charged particles concentrations, temperature electrons. axisymmetric geometry main elements structure is considered. Two approaches taking into account influence...
The radio-frequency ion thruster (RIT) is a gridded accelerator which used as an alternating electro-magnetic field for plasma production. It suggested to use the 0-D analytical model based on energy and particles balance equations RIT integral parameters estimation well quick analysis of influence design modification performance improvement. numerical results (geometry discharge chamber, input power, current) can be first assumption more complicated models (1-D or 2-D). calculations are...
This paper presents the results of plasma parameters probe studies in discharge chamber low power laboratory ion thruster. The measurement procedure based on use triple Langmuir placed into chamber's plasma. During measurements characteristics were collected automatically by data acquisition software created LabVIEW development environment. In current we discuss experiment: electron temperature Te distribution and number density ne hemispherical distributions obtained without applying an...
This paper considers the application of triple Langmuir probe method to investigate local plasma parameters radio frequency (RF) discharge that is placed in applied magnetostatic field. The main criteria applicability for such a experimental diagnostics RF presented. As an example, this presents results were obtained using proposed on one cross sections chamber ion source with influence field radial distributions charged particle density and electron temperature shown.
Abstract This article describes the activities carried out by RIAME MAI in field of low-power ion thrusters 2010-2020. The results study a laboratory model low power RIT using different shape GDC are presented. work on creating an experimental such with elements propulsion system shown. also presents research process erosion accelerating electrode - critical element thruster design from point view lifetime.
The work is devoted to the theoretical assessment of efficiency increase possibility for radio-frequency ion injector, which designed contactless removal space debris from near-earth orbit by using an antenna located inside discharge chamber. Four internal configurations and two external ones—end side—are considered. Expected characteristics were estimated engineering mathematical model built in COMSOL Multiphysics approximate magnetohydrodynamic description charged particle behavior....
The need for small satellites that may be used in space a long time has grown. One of the driving forces to come is advent light-weight and long-life solar arrays which are necessary electric propulsion having service life. Such combination new economical thrusters allows relatively cheap, fast reliable performance many missions can't performed using other technologies. This paper describes development at MAI 3 types: ion thruster, closed electron drift thruster colloidal one. Performance...
