In this paper, two-impulse Earth-Moon transfers are studied in a four-body model. For given departure, arrival orbits, the focus is on reconstructing the total set of possible solutions within a specified maximum transfer time. This is done by formulating the transfer as a nonlinear programming problem, and by solving it with direct transcription and multiple shooting. The outcome is analyzed in a cost vs. transfer time plane, where orbits showing their best balance are studied. With this approach, Hohmann, interior, and exterior transfers, as well as the existing literature, can be viewed as special points of a more general picture, where new solutions emerge.

Abstract
In this paper, two-impulse Earth-Moon transfers are studied in a four-body model. For given departure, arrival orbits, the focus is on reconstructing the total set of possible solutions within a specified maximum transfer time. This is done by formulating the transfer as a nonlinear programming problem, and by solving it with direct transcription and multiple shooting. The outcome is analyzed in a cost vs. transfer time plane, where orbits showing their best balance are studied. With this approach, Hohmann, interior, and exterior transfers, as well as the existing literature, can be viewed as special points of a more general picture, where new solutions emerge.| File | Dimensione | Formato | |
