Abstract
We will present surrogate-based robust shape optimization of transonic airfoils. A large number of geometrical uncertainties on the airfoil is modeled by a truncated Karhunen-Loève expansion to achieve a dramatic reduction of the large number of parameters. The combination of quasi Monte Carlo sampling and gradient-enhanced Kriging enables us to efficiently calculate statistics of the aerodynamic coefficients which are used to evaluate the objective function to be optimized in our robust design optimization framework.
