| 摘 要： | 针霍尔推力器应用于GEO卫星时，羽流会对太阳能翼板表面高透光玻璃盖片产生一定的影响，导致太阳能电池整体输入功率降低。因此，有必要针对羽流的影响对翼板表面进行一定的防护。在对目前国内外羽流安全性评估及防护方面的工作进行一定调研的基础上，针对SPT100应用于典型的GEO轨道卫星时的情况，利用SPIS软件运用混合单元粒子（PIC）方法模拟了两种可能的太阳能翼板羽流防护方案，并分析比较了每种方案的优缺点及防护效果，为推力器在轨飞行时的羽流防护提供一定的借鉴。

| Abstract: | The plume of the Hall thruster has negative effects on cover glasses of the solar panel which have high light transmission.Therefore, it is necessary to design some protective structures for solar array.Firstly, some related works were reviewed. Then, two different protection schemes were simulated using hybrid-PIC for a GEO satellite equipped with a SPT100. Finally, the advantages and disadvantages of the two schemes were analyzed and some valuable suggestions were proposed. The output power of solar array will be decreased if they are polluted. |
