The relation between aerodynamic induced drag and bending moment for the adaptive wing is studied analytically. Four flaps are attached to each of the wing leadingand trailing-edges, and they are applied with independent deflection angles. Totally 3,436 combinations of flap deflection angles are analyzed for the cruise condition of Mach number 0.78. The Static aeroelasticity analysis of MSC/NASTRAN using linear aerodynamics are conducted to acquire the aerodynamic pressures acting on the wing. The aerodynamic induced drag and the bending moment are derived from these pressure distributions. The analyzed results indicate that there is the Pareto Optimization Curve between the aerodynamic induced drag and the wing root bending moment. It is pointed out that the combinations of flap deflection angles on the Pareto Optimization Curve are effective if the aerodynamic performance is required adding to the structural healthiness.
