航天器磁力矩器在低轨道等离子体环境中的效应

Effect of spacecraft magnetorquer in LEO plasma

文章介绍了航天器磁力矩器在低轨道等离子体环境中的一些效应。以某型号卫星为例,计算了某型号磁力矩器产生的磁场,分析了等离子体在磁力矩器产生的磁场中的运动状态。经过建模计算,磁力矩器周围等离子体中的电子将在磁力矩器两端往复运动,而距离磁力矩器较远的电子将聚集在磁力矩器的两端附近。

Effects of spacecraft magnetorquer in the plasma environment of Low Earth Orbit(LEO) are studied in this paper. For the magnetorquer of a satellite,the related magnetic field is calculated and analysis is carried out on the plasma movement around the magnetorquer. Results show that electrons of the plasma around magnetorquer will make to-and-fro movement between the two ends of the magnetorquer,and electrons away from the magnetorquer will cluster around the two ends.
