随着技术的发展,微小卫星已经成为一种功能强大的航天器.为了进一步拓展微小卫星的应用领域,提升其任务效益,高敏捷机动能力成为了微小卫星发展的重要方向.控制力矩陀螺(CMG)因其具有高转矩能量比和低重量力矩比,将成为实现微小卫星敏捷机动的重要执行机构.介绍一种新型的可应用于微小卫星的微型CMG,其角动量为0.1 N·m·s.经过实验室测试和环境试验,结果表明该型CMG可满足微小卫星的姿态控制需求.
With the development of technology, micro-satellite has become a powerful spacecraft.In order to further expand the application field of micro-satellite and improve its mission efficiency, high agility mobility has become an important direction for the development of micro-satellite. ) Because of its high torque-to-energy ratio and low-weight moment ratio, it will become an important actuator for realizing microsatellite agility.This paper introduces a new miniature CMG which can be applied to micro-satellite with an angular momentum of 0.1 N · m · s After laboratory tests and environmental tests, the results show that this type of CMG can meet the needs of micro-satellite attitude control.
