本文报道了一种采用空心阴极的稳态外加磁场等离子体动力学（MPD）推力器的工作特性。为了提高阴极性能，采用空心阴极代替钨棒，使其具有更好的电子发射性能和更长的使用寿命。电极间采用矩形加速截面。测量了外加磁场、放电电流、推进剂质量流量、加速通道宽度和高度的变化对放电电压和推力的影响。
This paper reports operation characteristics of a steady-state, applied-field magnetoplasmadynamics (MPD) thruster using a hollow cathode. In order to improve cathode performance, a tungsten rod was replaced with a hollow cathode which had better electron emission performance and a longer lifetime. A rectangular acceleration section was employed between electrodes. The discharge voltage and thrust were measured with varying the applied magnetic field, discharge current, propellant mass flow rate and acceleration channel width and height.
