Abstract

To support the mission and trajectory design problems associated with the Earth-to-moon trajectories for a crewed vehicle, a multisegment lunar free-return trajectory is proposed. The multisegment free return differs from hybrid profiles in that it consists of free-return sections only; however, it maintains the advantages of hybrid returns. The analysis presented here is limited to a two-segment class of trajectories. In this profile, the translunar injection puts the spacecraft onto a free-return trajectory with a high perilune altitude; then, the spacecraft performs a transfer maneuver onto a new translunar coast trajectory that has an approximate perilune altitude of 100 km. This new translunar coast trajectory is also designed as a free-return trajectory that can perform a safe return. With a finite sphere of influence model, an analytical model of the multisegment free-return trajectories is developed by the matched-conic technique. Characteristics of the injection velocity, flight time, and lunar a...
