微小卫星用微型控制力矩陀螺研究

摘要： 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.

Miniature Control Moment Gyroscope for Small Satellites

Abstract：With the development of the aerospace technology, the demand for small satellites is increasing gradually. The agility of small satellites is a critical parameter, in the viewpoint of application field expansion and mission return maximization. The control moment gyroscope (CMG) exhibits better performances in terms of torque power and mass torque characteristics, which make it a key actuator for agile and precise attitude control. In this paper, a miniature CMG is developed for small satellites with 0.1 N·m·s angular momentum. The performance and the environmental tests of the CMG are discussed, which demonstrate that the requirement of small satellites attitude control is perfectly met.
