This paper explores the optimum wing bending and torsion deformations of a highly flexible mission-adaptive aircraft. With the goal of improving flight performance across the entire flight regime, a modal based optimization subject to trim and other constraints is employed. Distributed control loads are formulated and used to determine the optimization wing geometry as well. The optimization is then performed to achieve the best flight performance which is de-fined as minimum drag. This study explores the optimum wing geometry for steady level flight at a single velocity, a range of velocities, and a coordinated turn. Additionally, the study also explores the optimum wing shapes with the consideration of the trade-off between flight efficiency and ride quality, where a multi-objective optimization is performed, targeting for minimizing drag to improve performance and reducing the wing bending load of a gust to improve the ride quality.
