In this paper, we investigate the manifolds of three Near-Rectilinear Halo Orbits (NRHOs) and optimal low-thrust transfer trajectories using a high-fidelity dynamical model. Time- and fuel-optimal low-thrust transfers to (and from) these NRHOs are generated leveraging their ‘invariant’ manifolds, which serve as long terminal coast arcs. Analyses are performed to identify suitable manifold entry/exit conditions based on inclination and minimum distance from the Earth. The relative merits of the stable/unstable manifolds are studied with regard to time- and fuel-optimality criteria, for a set of representative low-thrust family of transfers.

由不变流形促进的向南 $$L_2$$ L 2 近直线晕轨道的低推力转移

在本文中，我们使用高保真动力学模型研究了三个近直线晕轨道 (NRHO) 的流形和最佳低推力转移轨迹。往返于这些 NRHO 的时间和燃料最佳的低推力传输是利用它们的“不变”歧管产生的，这些歧管用作长的终端海岸弧。执行分析以根据倾斜度和距地球的最小距离确定合适的歧管入口/出口条件。针对一组有代表性的低推力转移族，研究了稳定/不稳定流形的相对优点，涉及时间和燃料优化标准。
