As every second counts during rescue operations with injured persons, UAS (Unmanned Aerial Systems), especially multicopters at present, are increasingly being used in this context. UAS in tilt-wing configuration offer the possibility to support the operations even faster and more efficiently. Tilt-wing aircraft are characterized by their ability to perform efficient and fast forward flight for bridging longer distances as well as hover flight, allowing vertical takeoff and landing almost everywhere. Automation of the flight systems is necessary to reduce the workload of rescue forces during a mission. The automation must be developed to a level where the flight system can autonomously perform the flight tasks issued by a rescue force, including the planning of necessary flight paths. In this thesis, a novel method for automated flight path planning for tilt-wing aircraft in rescue operations is designed and evaluated. For the purpose of reacting ad hoc to inputs from a rescue force, flight paths are planned immediately in flight within a short time. The flight paths allow the specified flight tasks to be accomplished while considering flight mechanical constraints of the flight system, such as its minimum turn radius. Furthermore, external environmental influences, such as the prevailing wind, and the special characteristics of tilt-wing aircraft are taken into account. It is guaranteed that the flight paths lie within a given flight area and avoid static obstacles. The presented path planning method includes a path planning algorithm developed and optimized within the scope of this thesis. It was successfully validated for functionality, runtime, and path length in Monte Carlo simulations within challenging environmental conditions. In addition, the complete flight path planning method is applied in the context of a rescue exercise. In this exercise, it is shown that changes made by rescue forces are taken into account by planning and executing new flight paths during the flight. Thus, the flight tasks required by rescue forces can be performed successfully.
