Abstract

In order to assess the accuracy of the experimental and numerical methods used for the prediction of the dynamic derivatives, systematic investigations have been performed with the lightweight model DLR F12 using the new developed model support for dynamic tests MPM in the DNW-NWB. Static and dynamic force measurements and steady and unsteady pressure distribution measurements have been performed. Furthermore steady and unsteady pressure distribution measurements on the wind tunnel walls have been done during the latest test campaign. Using the DLR-TAU code steady, quasi-steady and unsteady calculations are performed. The comparisons of the experimental and numerical investigations yield to a very good agreements. Not only for the forces and moments but also the pressure distributions are necessary to predict the steady and unsteady aerodynamic characteristics accurately.
