传统蓄电池贮能系统由于其比能量小、可靠性低的固有缺陷已难以满足未来航天器的总体性能发展要求。近年来，随着高性能磁轴承、高强度轻重量的复合材料、电力电子技术等一系列关键技术的发展，使得飞轮贮能系统取代目前航天器中镍氢电池贮能系统成为可能。文中系统地阐述这一未来的航天器贮能系统，其中具体介绍了飞轮贮能系统的高比能量、长寿命、高效率等优越特性以及在航天器应用中独具的位姿控制附加功能，并对飞轮贮能系统的结构组成、多功能集成等方面作了较为详细的论述，最后介绍了目前飞轮贮能系统在航天器中应用研究的状况
Traditional battery energy storage system due to its specific energy, low reliability inherent defects have been difficult to meet the overall performance of future spacecraft development requirements. In recent years, with the development of a series of key technologies such as high-performance magnetic bearings, high strength and light weight composite materials and power electronic technology, it is possible to replace the existing Ni-MH battery energy storage system in spacecraft with the flywheel energy storage system. This paper systematically expounds the future spacecraft energy storage system, which introduces the superior features of high specific energy, long life and high efficiency of the flywheel energy storage system as well as the unique position and attitude control additional functions in spacecraft applications, And the structure of the flywheel energy storage system, multi-functional integration and other aspects made a more detailed discussion, and finally introduced the current application of flywheel energy storage system in spacecraft research status
