磁场对高电压霍尔推力器性能影响研究
|
摘要
为研究磁场构型、磁场强度对高电压霍尔推力器主要性能的影响机理,以HET-200推力器为对象,采用固定磁场构型和不固定磁场构型两种方案进行实验研究。结果表明,在不固定构型的情况下增强磁场,放电电流存在两个极小值,效率也存在相应的两个极大值;但当固定磁场构型时,则放电电流只有一个最小值,效率也只有一个最大值。以最优效率下的磁场构型为基准,获得了磁场与电压、磁场与流量的匹配关系分别为B_(r, max)∝V~(0.7),B_(r, max)∝m。
Aiming at studying the influence mechanisms of magnetic field configuration and intensity on the main performance of HETs under high voltage condition, this paper takes HET-200 thruster as an example to implement both fixed and unfixed magnetic field configuration methods to conduct the experimental research. The results indicate that for the unfixed magnetitic field configuration method, two local minimum discharge current values are acquired with the enhancement of magnetic field, and there are also two local maximum values of effiiency obtained correspondingly. Meanwhile, when the magnetic field configuration is fixed, the discharge current has only one minimum value and also only one maximum efficiency. Finally, based on the optimized magnetic field configuration, the matching relationship between magnetic field and discharge voltage, as well as magnetic field and anode flow rate are concluded as: B_(r,max)∝V~(0.7) and B_(r,max) ∝m.
