Abstract

This paper describes how transonic buffet over a supercritical airfoil can be alleviated using a contour bump passive control technique. Buffet control is formulated as a 4-parameter and 2-objective optimization problem which is solved using a Pareto-based genetic algorithm. Buffet suppression is achieved thanks to optimal bumps located between the shock wave and the trailing edge on the upper airfoil surface.
