The student will identify, investigate the feasibility of, and develop a novel ultra-high V mission scenario enabled by next-generation high Isp Hall effect ion thrusters. Initially, a wide array of missions will be analysed to assess feasibility and commercial potential. One specific mission will then be selected for an in-depth mission design, possibly including preliminary spacecraft design.The expected output of the PhD is at least one completed space mission design enabled by the next generation of ion thrusters.Due to the novel nature of these trajectories, the project may require the development of novel trajectory design tools for IRIDIS (HPC). They will be based on current dynamical systems-based methods including natural transport mechanisms under multi-body dynamics, relying on invariant manifolds, the weak stability boundary, and stability indicators such as FTLE and LCS. Classical transcription methods, Non-Linear Programming (NLP) based spectral direct transcription techniques of the dynamics, and shape-based trajectory design heuristics may also be used depending on the mission profile.Possible space missions may include:Earth to Moon: Space tug to GEO, multiple space debris removal, LEO in-orbit servicing/refuelling, sustainable Lunar gateway supply missionsMoon to Asteroid belt: Asteroid belt tour and deflection, large sample return, fast crewed mission to Mars, continuous asteroid miningJupiter and Beyond: Orbit insertion at outer solar system planets, stators for galactic travellers, reaching the Oort cloud

学生将识别、研究可行性并开发由下一代高 Isp 霍尔效应离子推进器实现的新型超高 V 任务场景。最初，将对一系列任务进行分析，以评估可行性和商业潜力。然后将选择一项具体任务进行深入的任务设计，可能包括初步的航天器设计。博士学位的预期成果是至少一项由下一代离子推进器实现的完整太空任务设计。由于离子推进器的新颖性这些轨迹，该项目可能需要为 IRIDIS (HPC) 开发新颖的轨迹设计工具。它们将基于当前基于动力系统的方法，包括多体动力学下的自然传输机制，依赖于不变流形、弱稳定性边界以及 FTLE 和 LCS 等稳定性指标。根据任务概况，还可以使用经典转录方法、基于非线性编程 (NLP) 的动力学光谱直接转录技术以及基于形状的轨迹设计启发法。可能的太空任务可能包括： 地月：太空拖船GEO、多次空间碎片清除、LEO 在轨服务/加油、可持续的月球门户补给任务月球到小行星带：小行星带游览和偏转、大量样本返回、快速载人火星任务、连续小行星采矿木星及更远的地方：外太阳系行星的轨道插入、银河旅行者的定子、到达奥尔特云
