摘要

为了解决Teflon脉冲等离子体推进器存在的性能低、有污染等问题

设计了以水为工质的脉冲等离子体推进器系统

并研究了它的主要工作指标的能量阈值。分析了水工质脉冲等离子体推进器系统的放电类型形成条件及原因

通过放电电压和电流测试实验

对工作能量阈值进行了实验研究

得到了稳定运行能量对应的储能电容值。实验结果表明:在足够高的电场强度和足够大的触发电流下

才能产生保证稳定工作触发概率的初始等离子体;而水工质脉冲等离子体推进器的正常工作能量范围由储能决定

与储能电容的容值不相关。研究结果为发展无污染、性能高、具有广适性的低功率水工质脉冲等离子体推进器打下了一定的基础。

Abstract

The paper designs a pulsed plasma thruster system based on water propellant and studies energetic threshold of its main working characteristics to solve the problems of low performance and high pollution of Teflon pulsed plasma thrusters. Based on an analysis of the forming condition and cause of electric discharge types

working energetic threshold is studied experimentally by the discharge voltage and current measurement.The study shows that the initial plasma that can provide trigger probability for steady operation and energy storage capacity are obtained only by enough electric-field intensity and trigger current

and the normal working energy range of the water propellant pulsed plasma thruster is decided by stored energies but not related to capacity values. The study provides a possibility for developing low power water propellant pulsed plasma thrusters of free pollution

high performance and wide applications.
