Subject of the thesis is the determination of periodic optimal flight trajectories. For this purpose, flight mechanics basics and appropriate optimization methods are dealt with. Then, trajectories are optimised for solar powered aircraft circling the world with the least possible mass penalty resulting from the batteries, for motor gliders with a retractable propulsive unit aiming to maximise range by conducting a saw-tooth flight, and for a bird performing a bounding flight to minimise the energy effort per distance travelled. In all cases, periodic trajectories result.
