摘　　要：双月旁转向轨道是实现"多任务、多目标"探测模式的理想工具,在以往的深空探测任务中得到了广泛的应用。首先,根据双月旁转向轨道的空间构型和特性,将其分为两大类:平面型和Backflip型;其次,基于"零影响球"和"CR3BP"两种模型,阐述了近旁转向轨道的基本原理;同时,讨论了平面型双月旁转向轨道的动力学特性和建模方法,并给出了其两类应用背景,与此相似,归纳了Backflip型双月旁转向轨道的原理和求解方法。对双月旁转向轨道开展的研究和分析工作能够为我国未来开展的行星际探测任务提供新的思路和参考。Double Lunar-Swingby （DLS） trajectories have received much attention due to its wide applications in the trajectory design of ＇ Multi-Mission and Multi-Purpose＇. First, the DLS orbits are divided into two classes named Plane type and Baekflip type according to their space configuration and characteristics. Then, the basic theory of swingby is shown based on two dynamics models of Zero-Sphere-of-Influence and CR3BP. Furthermore, both dynamics and modeling of Plane type DLS trajectory are discussed in two categories of application, and the principle and solution methods of Backflip type orbit is also summarized in detail. This study and survey about DLS trajectories could provide a new insight and reference for the interplanetary mission of China.
