Keywords: aerodynamics, high lift flows, and separation

A calculation method for predicting the performance of airfoils, multi-element airfoils, wings and multi-element wings based on an interactive boundary-layer approach using an improved Cebeci-Smith turbulence model is described. Inviscid flow solutions based on panel and full-potential methods are coupled to an inverse finite difference method using Veldman’s interaction law. Results are presented for single and multi-element airfoil as well as single and multi-element wing configurations. Overall calculated results show very good agreement with experiments..
