Optimality of intermediate-thrust arcs in rotating potential force fields
Abstract
Optimality conditions for intermediate-thrust arcs (IT-arcs) of rocket trajectories in rotating potential force fields where CORIOLIS-forces have to be taken into account are derived. For coplanar problems, the existence of IT-arcs in optimal time-free transfers depends on inequality conditions, based mainly on properties of the local potential field. Therefore, the region of the potential force field, where no time-free optimal IT-arc exists, can easily be evaluated. As an example the restricted three-body problem will be considered.
