Abstract [en]

During the aircraft's ight, the control surfaces that enable the aircraft to perform the required maneuvers and the actuator that control them have to withstand loads. Those loads will a ect the actuators lifetime and that is why it is very important to be able to predict their amplitude in order to make sure the actuators will last long enough and be ecient enough during the aircraft lifetime. Duty cycles are thus computed in order to compute the actuators fatigue severity and endurance criteria. The problem is that during the design of a new aircraft, duty cycles generation is very long process. The aim of this thesis it to predict the evolution of actuators fatigue with respect to design parameters in order to reduce computation time during incremental aircraft design.
