Description
A sequential algorithm for optimizing low-thrust Earth orbit transfers in terms of the propellant consumed is proposed. The dynamical model includes the effect of the Earth shadow and the J2 effect of the gravitational potential. The algorithm is based on two steps of growing complexity. In the first step, a near-optimal solution is obtained using simplified dynamics. In the second step, a hybrid approach embedded in a direct collocation scheme is used to consider the optimal coast arcs out of the Earth shadow. This novel approach is a continuation of a previous work in which the minimum time problem was solved. The ultimate goal of the work is to develop a robust and flexible tool that addresses the multi-objective design of low thrust transfers in Earth orbit. Hence, the user will not only obtain just point solutions, but will be able to explore the set of Pareto optimal trajectories for these two objectives.
