Abstract

The present paper focuses on the possibilities and strategies to model parametric and aircraft shapes with a high-end CAD system in the context of design optimization. As an example the modeling of a propeller with crescent-shaped blades is described. Additionally the problem of airfoil parameterization within a CAD system is also touched. The use of pa-rametric associative modeling starting from design tables and ending with CFD-ready ge-ometries is demonstrated for a wing body configuration. Finally, a novel method is introduced to support CFD volume mesh deformation with auxiliary structured surface grids. This will enable the use of parametric CAD in combination with the adjoint approach, what is still in open issue in design optimization.
