Abstract : Parameterization techniques commonly used in aerodynamic shape optimization are essentially general and multi-purpose approaches. As a consequence, they cannot be well suited to a particular shape optimization problem. The present study proposes a new method that adapts an initial and perhaps naïve parameterization of an aerodynamic shape by the Free-Form Deformation (FFD) technique, to the particular optimization problem to solve, according to a first approximation of the solution. This parameterization adaption method is included in a three-dimensional aerodynamic shape optimization procedure for Eulerian flows and is demonstrated for the design optimization of the wing of a business aircraft.
