摘要
通过总结过去五十年航天技术发展的特点,说明空间操作是未来空间活动的主流和必然。空间操作要求飞行器机动具有快速性、自主性、精确性以及大范围可达性。机动轨道不再是开普勒轨道,用于描述天体运动的开普勒理论已不能完全适用。提出了非开普勒运动的定义、内涵,对研究该问题的方法进行了探讨,提出了特例研究法和普遍研究法,最后提出了非开普勒运动的主要研究方向建议。所提出的非开普勒运动概念有助于更加深刻理解和研究空间机动的本质,可以牵引空间机动相关理论和技术的进一步发展,为新世纪航天技术发展奠定基础。
Based on the analyzing and summarizing of the technical characteristics of aerospace vehicles during its developmerit in past fifty years, it is pointed out that space operations will be the mainstream and necessity of future space activities. During space operation, it is required that spacecrafts can maneuver to a wide area quickly and accurately. So the spacecraft orbits are not belongs to Keplerian orbit and the description of celestial bodies motion by Keplerian theory is not valid yet. This paper describes the connotation of Non-Keplerian motion, discusses the methods for studying this problem, and puts forward the special and general method. Then the main research areas of Non-Keplerian motion are suggested. The concept of Non-Keplerian motion given in this paper can help to understand and investigate the essence of space maneuvering, can promote the development of correlated theory and technology of space maneuvering and help to establish the basement of future space technology.
