Abstract

The objective of the presented work is to demonstrate the benefits of using numerical optimization of high-lift multi-element airfoils based on RANS-simulation in practical design. It is first shown, that the design methodology chosen in the presented framework is able to detect optimal configurations determined by wind tunnel tests. Beneath this basic statement sensitivities for the validity of the obtained results are outlined. Finally the method is applied to the drag reduction of a 3-element airfoil.
