Hall thruster is an electric propulsion device for attitude control and position maintenance of satellites. The discharge process of Hall thruster will produce divergent plume. The plume will cause erosion, static electricity, and other interference to the main components, such as solar sailboard, satellite body, and thruster. Therefore, reducing the divergence of the plume is an important content in the research of thruster plume. The additional electrode to the plume area is a way to reduce the divergence angle of the plume, but there are few related studies. This paper uses the particle-in-cell (PIC) simulation method to simulate the effect of the additional electrode on the discharge of the Hall thruster, and further explains the effect mechanism of the additional electrode on parameters such as the electric field and plume divergence angle. The simulation results show that the existence of the additional electrode can enhance the potential near the additional position. The ...

通过粒子模拟研究附加电极对霍尔推进器羽流的影响

霍尔推进器是一种电动推进装置，用于卫星的姿态控制和位置维护。霍尔推进器的排放过程将产生发散的羽流。羽流将对主要部件（例如太阳能帆板，卫星机身和推进器）造成侵蚀，静电和其他干扰。因此，减小羽流的散度是推进器羽流研究的重要内容。羽流区域的附加电极是减小羽流发散角的一种方法，但相关研究很少。本文使用粒子模拟（PIC）方法来模拟附加电极对霍尔推进器放电的影响，并进一步说明附加电极对诸如电场和羽流散度等参数的影响机理。角度。仿真结果表明，附加电极的存在可以增强附加位置附近的电势。的...
