Summary

A post-parametrization method, based on freeform deformation techniques, has been established to simplify and to automate the parametrization of shapes from CAD-models, to be used for aerodynamic design. To create the necessary deformation lattices, structured grid generation techniques of a grid generation system, developed at DLR, are utilised. As this grid generation system has the salient feature to store and to replay a sequence of processes with different parameter settings, a deformation of the shape, given by polygonal curves and surfaces, can be controlled quantitatively. In two examples the applicability of the method for aerodynamic wing design and detailed design of a wing tip is demonstrated.
