	abstract = {Shape deformation methods are commonly used for aerodynamic design optimization of physical bodies. These methods promise a good trade-off between high design variations and a minimal set of optimization parameters. Free-form deformation and deformations based on radial basis functions are among the current state-of-the-art linear deformation methods. Recently, both methods have been analyzed on their capabilities in a simulation-based design optimization from a academic and application oriented benchmark point of view. In this paper we enrich the analysis by studying both methods with respect to applications in aerodynamic design optimization. Calculating typical aerodynamic properties such as pressure gradients at the shape surface and turbulent Reynolds stresses in the downstream wake for a set of deformed airfoil wings using computational fluid dynamics simulations allows for a comparison of possible implications for each shape deformation technique on an optimization success. As a consequence, this paper provides recommendations on the usage of the different shape deformation techniques in aerodynamic design optimizations based on properties inherently present in the deformation methods.},
