Shape Parameterisation Based on Freeform Deformation in Aerodynamic Design Optimization

Abstract

Shape parameterisation has been identified as an important task for aerodynamic design optimization. A method based on freeform deformation has been established, which enables in combination with grid generation software parameter-controlled variations of given shapes. The applicability and flexibility of the method for aerodynamic wing shape optimization has been demonstrated. For verification of the method airfoil recovery tests have been performed
