论文摘要
本文阐述了中间点（IP）的概念，其作为沿星际轨迹的节点并入的概念，以及如何允许将轨迹确定和优化到星际对象（ISOS）。 IP可用于建模太阳能操作（SOM）以及Vinfnity oververver aneuuvers（VLM）。 SOM在理论上是一种重要机制，可以通过该机制快速退出太阳系，并且可以实现ISO的拦截。 VLM实际上已被证明是一种减少整个任务Delta-V以及发射时的特征能量C3的方法。因此，可以通过这两个应用程序分析任务对星际对象（ISO）（例如1i/oumuamua）的可行性。为此分析利用的行星际轨迹优化器工具，允许IP选择作为沿相关星际轨迹的相遇选项。 OIT采用沿轨迹的离散点的脉冲推力的假设，该假设通常在高推力推进方案（例如化学或核热）中有效。
This paper explicates the concept of an Intermediate Point (IP), its incorporation as a node along an interplanetary trajectory, and how it permits the determination and optimization of trajectories to interstellar objects (ISOs). IPs can be used to model Solar Oberth Manoeuvres (SOM) as well as Vinfnity Leveraging Manoeuvres (VLM). The SOM has been established theoretically as an important mechanism by which rapid exit from the solar system and intercept of ISOs can both be achieved; the VLM has been demonstrated practically as a method of reducing overall mission Delta-V as well as the Characteristic Energy, C3, at launch. Thus via these two applications, the feasibility of missions to interstellar objects (ISOs) such as 1I/Oumuamua can be analysed. The interplanetary trajectory optimizer tool exploited for this analysis, OITS, permits IP selection as an encounter option along the interplanetary trajectory in question. OITS adopts the assumption of impulsive thrust at discrete points along the trajectory, an assumption which is generally valid for high thrust propulsion scenarios, like chemical or nuclear thermal for instance.
