摘要
霍尔(Hall)推力器的磁场设计是提高其性能的关键技术之一。针对传统环形Hall推力器小型化带来的缺点,提出了圆柱形的Hall推力器。简要对比了环形和圆柱形两种推力器,对圆柱形推力器的工作原理、磁场设计的要求以及利用ANSYS有限元软件进行的电磁场数值模拟的结果进行了详细分析。结果表明,圆柱形推力器磁路设计是合理的,另外也证明了用ANSYS有限元软件进行电磁场模拟的可靠性。
The magnetic field design of a Hall thruster is essential to the engine performance improvement. Cylindrical Hall thruster was proposed in this paper considering disadvantages of traditional ring-shaped Hall thruster minimization. A brief comparision was made between ring-shaped and cylindrical Hall thruster. Detailed analyses on the principles of operation, the magnetic field design requirements as well as the numerical simulation results obtained through ANSYS finite element software of the cylindrical thruster were conducted. The results indicated that this cylindrical booster magnetic circuit design is reasonable, moreover reliability of the ANSYS finite element software which was used to simulate the electromagnetic field is proved.
