摘要
为了研究工作参数和结构参数对射频离子推力器放电性能的影响规律,通过开展放电室均布模型数值仿真和推力器性能试验,研究了射频离子推力器LRIT-40的放电机理和放电性能随结构参数和工作参数的变化规律。研究发现,减小长径比或增大工质流率、栅极电压及射频功率均能增大推力器束电流,改善推力器性能。通过分析试验结果和仿真结果得到,放电室均布模型可用于研究射频离子推力器的性能。
A uniform model of RF-ion thruster discharge chamber was established to research the discharge principles and regulations among RF-ion thruster working parameters,geometry parameters and its discharge performances.The solution of model and conclusions of test is compared in the paper.It is found that by reducing the aspect ratio or increasing the mass flow rate,the grid voltage and the RF power can increase the thrust beam current and improve the thruster performance.Test and simulation results show that the discharge chamber uniform model can be used to study the performance of RF ion thrusters.
