霍尔推力器性能评估技术及概况

PERFORMANCE EVALUATION TESTING OF HALL THRUSTER

摘要: 以SPT-100稳态等离子推力器为研究对象,结合国外实验情况,计算推力器比冲,发现效率的改变与推力器运行参数有关。推力器压力的升高会导致流率的升高,而流率的变化与放电电压和漂浮电压无关。通过研究获得更大的推力和更高的比冲。

Abstract: A performance test of the Stationary Plasma Thruster SPT-100 is described.With the analysis of NASA,variations in thruster performance appear related to variations in thruster operating characteristics.Large variations in thruster performance are associated with oscillations in the discharge current and voltage.
