| 摘 要： | 采用试验方法研究了微阴极电弧推力器中峰值放电电流及外加磁场对其推力、比冲、寿命的影响规律。试验结果表明:峰值放电电流增加,阴极烧蚀量增加,元冲量增大;相比于较低的峰值放电电流(10A),更高的峰值放电电流(40A)可延长推力器的工作寿命;外加磁场增强,推力器喷射等离子体轴向速度增大,比冲增加。

| Abstract: | The influence of peak discharge current and external magnetic field on the thrust, specific impulse and lifetime of the micro-cathode arc thruster was studied by the test method. The results show that the peak discharge current increases, the cathode ablation increases, and the element impulse increases; compared with the lower peak discharge current (10A), the higher peak discharge current (40A) can extend the working life of the thruster; with the increasing of the applied magnetic field, the axial velocity of the plasma jet is increased, and the specific impulse of the thruster is increased. |
