A robust and efficient approach to the multipoint constrained design is extended to optimization of 3D aerodynamic wings. The objective is to minimize the total drag at fixed lift in the presence of various geometrical and aerodynamic constraints, including the constraint on the pitching moment. For the considered class of problems, significant aerodynamic gains have been obtained.
