One-dimensional Models of Stationary Plasma Thruster
A stationary plasma thruster (SPT, or Hall Thruster) is an electromagnetic thruster whose properties make it especially suitable for applications such as satellite station-keeping. Fig. 1 represents schematically the geometry of the SPT. Xenon is injected from the anode (rate on the order of 5mg/s), at the end of the dielectric cylinders and on the cathode side, outside the cylinders. We are ma...
متن کاملUltra-Low Power Stationary Plasma Thruster
Preliminary results are presented for the operation of a very low power stationary plasma thruster. The thruster design is co-axial, with a 0.5 mm channel width and 4 mm outer channel diameter and is intended to be approximately 1/100 the scale of a typical 1 kW thruster. The magnetic circuit employs a permanent magnet core generating a peak magnetic field of ~ 10 kG. Successful operation is ac...
متن کاملSimulation of a Helium Atmospheric Plasma Jet Using Fluid Equations
In this study, a cold atmospheric He plasma jet is investigated. The jet is of dielectric barrier discharge type, consisting of a dielectric tube with two metal ring electrodes. The continuity, momentum and energy conservation equations as well as the Poisson equation for obtaining the potential and the electric field, accompanied with the ideal gas laws, are used for the simulation. The result...
متن کاملModeling of a Pulsed Plasma Thruster; Simple Design, Complex Matter
Experiments conducted at the Surrey Space Centre on a breadboard pulsed plasma thruster (PPT) have led to greater insights in to the underlying principles of electrode erosion during plasma formation. It has been shown that during a PPT discharge a significant proportion of the plasma that is produced is from direct erosion of the electrodes to the extent that traditional Teflon propellant bars...
متن کاملComputational Modeling of Stationary Plasma Thrusters
A 2-D axisymmetric hybrid PIC-MCC model of the acceleration channel and near-field of dielectric wall-type Hall thrusters is tested on an SPT-100 type and a UM/AFRL P5 magnetic field configuration. The location of both the virtual cathode line (VCL) and virtual anode line (VAL) are varied on the SPT-100 type magnetic field configuration to study the model dependence on these parameters. A P5 si...
