螺旋霍尔推进器是一种两级推进器，它的开发是为了研究射频电离阶段是否可以提高在高推力和低比冲下运行的霍尔推进器的整体效率。本文描述了在10-25 mg/S氙阳极质量流量、100-200 V放电电压、6 mg/S的Ar和200 V的氮气的条件下，测量螺旋霍尔推进器单级和二级性能的实验。在两级运行过程中，螺旋霍尔推进器的推力随射频功率的增大而略有增加，但推进效率和推力功率比均随射频功率的增大而减小。探头诊断表明，推进剂效率略有提高是实现增益的主要原因，但不利于提高推进剂的使用效率。
The helicon Hall thruster is a two-stage thruster that was developed to investigate whether a radio frequency ionization stage can improve the overall efficiency of a Hall thruster operating at high thrust and low specific impulse. This paper describes an experiment that measured the single-stage and two-stage performance of the helicon Hall thruster operating at 10–25 mg/s anode mass flow rates of xenon at 100–200 V discharge voltages, and also for 6 mg/s of argon at 300 V, and 2.6 mg/s of nitrogen at 200 V. The helicon Hall thruster performance during operation with argon and nitrogen is characterized by low beam divergence efficiency and low propellant utilization efficiency. During two-stage operation, the thrust of the helicon Hall thruster marginally increased with radio frequency power, but the propulsive efficiency and thrust-to-power both decreased with increasing radio frequency power. Probe diagnostics suggest that gains were realized by a slight increase in propellant efficiency, but that t...
