Effects of the peak magnetic field position on Hall thruster discharge characteristics

摘要: Abstract With the development of electric space propulsion and all-electric technologies, application range Hall effect thruster (HET) has gradually expanded. As an important part HET, magnetic field plays a decisive role in its performance. In versatile HETs, it is necessary to comprehensively thoroughly understand effects on HET discharge characteristics. this paper, HEP-100X with multiple degrees freedom terms control used study peak position The results indicate that can effectively main ionization zone affect rate. best comprehensive performance when located near channel exit. Further analysis reveals improvement mainly due reduced ion loss wall surface plume divergence half-angle, increased current utilization efficiency voltage efficiency. shows above trends under various flow conditions, anode highest 50 sccm. condition, propellant sufficiently ionized small. This research provides support for understanding significance process, design optimization multifunctional thrusters subsequent research.
