A new method for airfoil shape optimization is presented, in which the airfoil shape is optimized not only for the best aerodynamic efficiency but also for the minimum structural weight. To relate the structural weight to the airfoil shape a series of methods are prescribed for initial sizing of the wingbox structure. Based on these methods, a “weight index” is defined. The airfoil weight index is a mathematical equation that relates the structural weight of the wingbox to the airfoil shape. The structural weight of a wingbox reduces by increasing the weight index of the airfoil. A set of multi-objective optimizations is performed to find the Pareto front of the airfoil drag and the weight index.
