目前可用或可实现的应用磁场磁等离子体动力学（AF - MPD）推进器的功率范围为5 - 100 kW，由于其高的比冲、足够的推力和紧凑的几何结构，似乎非常适合于大型卫星的轨道变化和静止（阻力补偿）。它们在近20年前发展到相当成熟，但由于缺乏任务、适当的功率和资格，尚未在太空中使用。有证据表明，这些发动机无法在实验室中实际操作，主要是因为即使在非常低的真空度下，也需要高真空来排除与羽流的未知环境相互作用。需要进行空间实验来证明Isp和效率。国际空间站现在提供了在太空中对发动机进行鉴定的机会。本文介绍了AF - MPD推进器的应用潜力、性能特点和技术现状，以及有待解决的应用问题，并提出了在空间光条件下运行和研究该发动机的空间实验。
Currently available or realizable applied e eld magnetoplasmadynamic (AF‐MPD) thrusters operating in the power range 5‐100 kW appear to be excellently suited for orbit change and stationkeeping (drag compensation) of large satellites because of their high specie c impulse, sufe cient thrust, and compact geometry. They were developed to considerable maturity almost 20 years ago, but have not yet been used in space because of the lack of missions, appropriate power, and qualie cation. There is evidence that these engines cannot be operated realistically in the laboratory, mainly because of the high vacuum needed to exclude unknown environmental interaction with the plume, even at very low vacua. A space experiment is needed to provide proof of Isp and efe ciency. The International Space Station now provides the opportunity to qualify the engine in space. This paper describes the application potential, performance characteristics, and technological status of the AF‐MPD thruster, remaining application issues to be resolved, and a space experiment proposed to operate and investigate the engine under space-e ight conditions.
