摘要

研究了美国国家航空航天局欧罗巴快船航天器反作用轮组件的磁屏蔽概念。为了减轻欧罗巴快船上的两个磁敏感科学仪器与反作用轮组件(RWA)之间的磁不相容，进行了这项研究。考虑到反作用轮组件的质量和空间设计的限制，考虑了两个磁屏蔽概念:(1)使用mu金属材料对RWA轮单元的内部磁体进行磁屏蔽;(2)使用metglass材料对整个RWA轮单元进行磁屏蔽。

Magnetic Shielding Concepts for Reaction Wheel Assembly on NASA Europa Clipper Spacecraft

Magnetic shielding concepts were investigated for the Reaction Wheel Assembly on the NASA Europa Clipper spacecraft. This investigation was performed in order to mitigate the magnetic incompatibility between the Reaction Wheel Assembly (RWA) and the two magnetically sensitive science instruments on the Europa Clipper spacecraft. Given the Reaction Wheel Assembly's mass and space design constraints, two magnetic shielding concepts were taken into consideration: (1) magnetic shielding of the internal magnet of the RWA Wheel Unit using Mu-metal material and (2) magnetic shielding of the entire RWA Wheel Unit using Metglas material.
