Strong adverse pressure gradients applied to a wake can cause off-the-surface separation in the wake, which is known as wake bursting. Three high-lift multielement airfoils, consisting of a main element and two flaps, were designed to improve aerodynamic performance and to mitigate wake bursting relative to a baseline airfoil. Two airfoil designs incorporating only modifications to the main-element airfoil are presented for target Reynolds numbers of 1×106 and 3×106. A third airfoil is presented for which the geometry of the main element and both flaps was modified. The designed airfoils exhibited an increase of Cl=Cd by as much as 17% relative to the baseline geometry as predicted by USM3D, an unstructured RANS solver. Improvements were made by incorporating increased laminar run and improved main-element wake behavior.
