Under certain combinations of speed and incidence, commercial aircraft can experience transonic buffet. Buffet consists of periodic self-sustain loads which cause wing vibrations, consequently reducing the aircraft performance, maneuverability and safety. The objective of this work is to apply bio-mimetic wings characterized by wavy leading- and trailing edges to control buffet. To further investigate the mechanisms of buffet, a numerical method based on global stability has been validated against high-fidelity simulations and applied to full-aircraft configurations. Different characteristics of wavy leading- and trailing-edges have been studied for both periodic and finite wings. When wavy leading-edges were used, transonic buffet was weakened and the related unsteady loads reduced.
