Beschreibung
The thesis presents new methods for the calculation of optimal aircraft trajectories as well as for the solution of special bilevel optimal control problems combining a superordinate optimization problem with subordinated optimal control problems. A scalable, multi-fidelity simulation model including an inversion controller constitutes the basis for the optimization process. Initial guesses for the optimization utilizing a non-linear 6-Degree of Freedom simulation model are generated from the optimal solution for a point-mass simulation model. The efficient solution of the bilevel optimal control problems is done by a post-optimal sensitivity analysis for the analytical calculation of the gradients.
