Dynamic load control offers a high potential for the improvement of aerodynamic performance and increase in passenger comfort. However, it is unclear if the implementation is feasible or even possible regarding the actuation system design. The demand of actively reducing gust loads acting on the wing results in challenging requirements for the actuation systems regarding high actuation speeds and loads. In this paper, promising actuation concepts for fast actuated droop noses and flap-tabs will be analysed based on preliminary designs. Furthermore, the impact on the overall system level is discussed.
