摘　　要：脉冲等离子体推力器的性能受电气参数、结构设计参数等方面的影响.针对脉冲等离子体推力器效率低的问题进行了理论分析并设计实验进行了验证,研究了设计参数与推力器性能之间的关系.结果表明,推力与放电电流有密切的关系,而脉冲等离子体推力器的电极间距、放电能量等设计参数对推力、放电电流等又有较大的影响.实验结果对设计高性能的推力器有参考价值.The performance of pulsed plasma thruster （PPT） is influenced by electric and structural param- eters. For the low thrust efficiency of pulsed plasma thruster, the correlation between the designing parameters and performance was studied through theoretical analysis and experimental investigation. The result shows that the thrust and discharge current are closely related. The change of the electrode gap and discharge energy in pulsed plasma thruster will influence the thrust and discharge current significantly. The experimental result implies considerable information to the design of an optimized thruster.
