A robust and accurate method for the multipoint CFD driven constrained optimization of 2D airfoils for minimum drag, previously developed by the authors, is extended to the optimization of 3D lifting surfaces for wing-body aircraft configurations. The objective is to minimize total drag at fixed lif...
