Abstract

Aeroelastic investigations increasingly apply modern CFD methods for unsteady aerodynamics. For 3D problems the wing is often still sim- plified to a great extent as was done in formerly-used linear methods(thin geometrics, no geometric deformation). The neglected details ofthe geometric model of a wing are, for example, static bending and torsion as they appear on the big wings of modern passanger aircraft at travel speed, as well as the modelling of the exact form of the wingtip. All of these details have an influence on the unsteady phenomena of Euler solutions. This influence is shown, e.g. on the AMP wing for various types of models. The main objective here is the comparison of unsteady Euler solutions of different models of the same wing. In some cases there is a differnce in the solution - in pressure distribution as well as in intergral coefficients.
