The paper presents the design and optimization of a morphing airfoil, able to change its shape harmonically in a passive way, with the aim of alleviating the loads developed by sinusoidal gust. The study is purely two-dimensional and performed exclusively in the frequency domain, so considering a linear behavior of the aerodynamics. The K ussner and Schwartz frequency domain model is applied to describe the unsteady aerodynamics. An airfoil with the Fishbone architecture has been chosen, as structural system. Such design allows the insertion of pressure chambers in the spine region in order to adaptively modify the chordwise bending stiffness of the structure and to adapt its performances to the frequency of the gust.
