| contents | The problem of minimizing the transfer time between periodic orbits in the Earth-Moon elliptic restricted three-body problem using a multi-mode propulsion system is considered. By employing the true anomaly on the primary orbit as the independent variable and introducing normalized time as an additional state, the need to repeatedly solve Kepler's equation at arbitrary epochs is eliminated. Furthermore, a propellant constraint is imposed on the high-thrust mode to activate the multi-mode capabilities of the system and balance efficiency with maneuverability. The minimum-time optimal control problem is formulated as a three-phase trajectory consisting of a coast along the initial periodic orbit, a controlled transfer, and a coast along the terminal periodic orbit. The three-phase optimal control problem is then solved using an adaptive Gaussian quadrature direct collocation method. Case studies are presented for transfers from an L2 southern halo orbit to a near-rectilinear halo orbit, analyzing the impact of different single- and multi-mode propulsion architectures and varying propellant constraint values. Finally, the methodology developed in this paper provides a systematic framework for generating periodic orbit transfers in three-body systems using single- and multi-mode propulsion systems. |
