摘要: |
混合轨道是载人登月轨道的重要类型之一。利用混合轨道的组成特点,提出在双二体假设下以自由返回轨道为基础的混合轨道计算方法。主要对混合轨道的特性进行分析,给出混合轨道在能量消耗和飞行时间等方面的特性。在涉及月球运动的计算时,考虑月球运动的非圆性,对传统双二体假设略作修改。给出混合轨道的设计实例,仿真结果验证了本文提出方法的有效性。 |

Abstract: |
Hybrid trajectory is one of the most important trajectory types for manned lunar landing mission. Using the componential characteristic of hybrid trajectory, a hybrid trajectory calculation method based on free return trajectory was proposed under double two-body model. Then, the major characteristics of hybrid trajectory were analyzed, such as energy requirement and time of flight. A little modification was made when calculating the ephemeris of the Moon, in which the Moon motion around Earth was considered as noncircular orbit instead of circular orbit. Finally, a design example was presented while the results of the simulation validate the method proposed. |
