Summary

A wind tunnel test section setup is described, which allows an automated analysis and optimization of the aerodynamic performance of two-dimensional three-element high-lift systems by varying the slat and flap settings. The gap, overlap and angle of attack of the high-lift devices are varied by remote by means of side wall integrated flush mounted traverses. The side wall implemented balance system is able to measure lift, drag and pitching moment of each of the high-lift system elements (slat/main section/flap) individually. Finally, results of a systematic analysis of the aerodynamic performance depending on the flap setting as well as an automated flap setting optimization using the Nelder-Mead method [1] are demonstrated.
