Tour Design Using Resonant-Orbit Invariant Manifolds in Patched Circular Restricted Three-Body Problems

It is increasingly desirable to incorporate multibody effects in tour design early in the process to both discover new solutions and reduce the number and size of required maneuvers. Flybys have previously been designed using the heteroclinic connections of resonant orbits in the circular restricted three-body problem (CRTBP), but tour design often requires the consideration of additional moons, especially within the Jovian system. In this study, the heteroclinic connections of multiple resonant orbits are chained together within separate CRTBP models to perform multiple flybys that advance through desired resonances. Methods for patching these trajectories together are explored, and sample trajectories are computed.
