A pulsed electric thruster named Pulsed Electrogasdynamic (PEG) thruster was investigated. In this thruster, the propellant gas is accelerated gasdynamically to high exhaust velocities ($10–15\mathrm{km}/\mathrm{s}$) by pulsed electric discharge. Laboratory models of the PEG thruster were developed and successfully operated for evaluation of performance potentials. The PEG thruster is intended for in-space propulsion such as in-orbit maneuver for small satellites and attitude control and station-keeping for larger satellites. In this paper, we discuss the background of the thruster concept, experimental research for performance evaluation, and potential applications. It is concluded that the PEG thruster, when developed to technical maturity, will be a simple, robust, and lightweight thruster for in-space propulsion.

研究了一种名为脉冲电气动力（PEG）推进器的脉冲电动推进器。在这种推进器中，推进剂气体被气动地加速到较高的排气速度（$10–15\mathrm{公里}/\mathrm{s}$）通过脉冲放电。开发了PEG推进器的实验室模型，并成功运行以评估性能潜力。PEG推进器用于太空推进，例如小型卫星的在轨机动，以及大型卫星的姿态控制和站位保持。在本文中，我们讨论了推进器概念的背景，性能评估的实验研究以及潜在的应用。结论是，PEG推进器在技术成熟时将是一种简单，坚固且轻巧的推进器，用于太空推进。
