Mitigation of transonic shock buffet on a supercritical airfoil through wavy leading edges

Physics of Fluids Degregori E. & Kim J.W. Transonic aircraft design has technological challenges in terms of fuel consumption, fluid-structure interaction, and noise emission. These include “drag divergence” that decreases the wing efficiency and “shock buffet” that generates an unsteady loading. In this paper, a new wing design concept by means of wavy leading edges …
