Title: Parallelized Aerodynamic Design Optimization of 3-dimensional Wing
Abstract: An efficient aerodynamic design optimization method for 3-dimensional wing is developed. A gradients-based optimization is adopted to find optimum, and adjoint equations are used for sensitivity calculations. The computational efficiency is improved by using a tightly coupled approach with step size estimation, multigrid DADI flow analysis and parallel computing. To show the efficiency of present method, a drag minimization problem of ONERA M6 wing under transonic flow conditions is presented.
