Keywords: MDO, Winglet, ANOVA, Kriging

A MDO technique with high-fidelity analysis was applied to the winglet design. CFD with the mid-field drag decomposition method contributed to accurate drag prediction, while minimum structural weight for each individual was evaluated by FEM analysis. Practical design decision was explored by coupling obtained design information with some design criteria.
