Trajectories characterization of an autonomous aerial vehicle with a small angle of attack

This paper presents a characterization of trajectories for an autonomous fixed wing aerial vehicle with a small angle of attack. The characterization is a preliminary stage in the design of a trajectory planner. After the definition of the two equality constraints due to under actuation, our study leans on a category of the trajectories known as trim trajectories, and the optimal manner to traverse these trajectories, by respecting the two dynamic constraints of under actuation as well as the constraints of inequality related to the limitations on the actuators. Finally, we present the results obtained for some elementary trajectories.
