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 کاملHybrid-PIC Simulation of a Hall Thruster
Although several operational codes are available for the prediction of plume dynamics of Hall thrusters and their interactions with spacecraft surfaces, their coverage of the range of physical phenomena involved and their ability to model complex geometries and material combinations has tended to be fairly restricted. We have initiated the development of a more comprehensive suite of models int...
متن کاملDevice and Plume Model of an Electrothermal Pulsed Plasma Thruster
Progress in combined device/plume modeling is presented for a Teflon-fed, pulsed plasma thruster from plasma generation to the plume far field. In this work we apply a one-dimensional unsteady model for the plasma generation and acceleration process. A new kinetic ablation algorithm is employed to calculate the Teflon ablation rate as a function of plasma parameters. A near cathode sheath model...
متن کاملNumerical investigation of a Hall thruster plasma
The dynamics of the Hall thruster is investigated numerically in the framework of a one-dimensional, multifluid macroscopic description of a partially ionized xenon plasma using finite element formulation. The model includes neutral dynamics, inelastic processes, and plasma–wall interaction. Owing to disparate temporal scales, ions and neutrals have been described by set of time-dependent equat...
