Design and application of low energy transfer orbit based on Lissajous staging post

Lissajous orbit is a kind of quasi-periodic orbit, which has rich shape choices, more mission flexibility and less fuel consumption required for orbit maintenance. Therefore, it can be used as a staging post orbit for the future construction of the cislunar space Airline-flight-mode transportation network. Low-energy transfer orbits from low Earth orbit to the Lissajous staging post will be the basis of building an economic and sustainable transportation system. However, the characteristics of low energy transfer orbits based on Lissajous staging post are currently unclear, and for the staging post orbits whose invariant manifolds are far from the moon, the maneuvering insertion strategy adopted in the traditional three-maneuver design method cannot fully utilize its advantages in reducing fuel consumption. In view of the above issues, a design method of three-maneuver low-energy transfer combining patched manifold and lunar flyby is proposed. The dimension of the optimization problem is reduced by piecewise solution, and the optimal solution is obtained by bi-level optimization. The results show that the above design method can reduce transfer fuel consumption by about 18-400 m/s for some orbit insertion points, effectively increasing the range of optional insertion points, and is also applicable to large amplitude Lissajous staging post orbits. Finally, the variation characteristics of flyby azimuth, flyby height, orbital insertion position, and other celestial gravity effects are emphatically analyzed. The results have important reference value for the selection of staging post orbits, launch windows, and orbital insertion points in future cislunar space Airline-flight-mode transportation networks.
