A new passive load reduction system, using coupled leading and trailing edge flaps, was developed at TU Darmstadt and investigated experimentally and numerically. The experiments were performed in the wind tunnel of the University of Oldenburg, where sinusoidal inflow conditions, representing for example the tower blockage effect, were created by means of an active grid. The numerical investigations were performed at the University of Stuttgart, using a quasi two-dimensional setup and a block structured CFD solver. In the present paper, a brief description of the experimental setup is given, whereas the numerical setup, in particular the realisation of the wind tunnel conditions, is presented in more detail. Moreover, a comparison between the measured and simulated loads for an airfoil with and without adaptive camber concept is discussed.
