综述了脉冲等离子体推力器35年来的发展和应用历史。PPT的工作原理是在固体绝缘体的暴露表面产生脉冲大电流放电，例如t棒上的三通。电弧放电从该表面烧蚀材料，从而提供被电离、加热并加速到高速的推进剂。通常，电流脉冲持续几微秒，由电容器驱动，大约每秒充电和放电一次。排气速度范围从3到50公里/秒，取决于PPT设计的细节。我们回顾了PPTs的基本物理特性和类型，并讨论了电子和实验室版本的性能，特别关注速度和羽流测量。我们还介绍了PPT理论和建模的现状，重点是质量演化和等离子体加速，并描述了PPT操作、实验室推力测量技术和PPT效率的各个组成部分的最新变化。
The 35-year history of the development and application of the pulsed plasma thruster (PPT) is reviewed. The PPT operates by creating a pulsed, high-current discharge across the exposed surface of a solid insulator, such as a Tee on t bar. The arc discharge ablates material from this surface, thereby providing propellant that is ionized, heated, and accelerated to high speed. Typically, the current pulse lasts for a few microseconds, driven by a capacitor that is charged and discharged approximately once per second. Exhaust speeds range from 3 to 50 km/s, depending on the details of the PPT design. We review the basic physics and types of PPTs, and discuss the performance of e ight and laboratory versions, with special attention to velocity and plume measurements. We also present the status of PPT theory and modeling, with emphasis on mass evolution and plasma acceleration, and describe recent variations on PPT operation, laboratory thrust measurement techniques, and the separate components of PPT efe ciency.
