This report describes a research effort demonstrating the concept of variable stiffness tailored aeroelasticity for smart structures. In particular, a wing structure is designed, or tailored aeroelastically, as a force multiplier for control actuation. This variable stiffness concept may be used as a way to employ light-weight and low-power output smart materials in lifting surface structures. A simple, unswept, rectangular wing model is used to explore the feasibility of utilizing the variable stiffness tailored structure as a force multiplier in conjunction with an outboard, trailing edge control surface. This approach involves the design of a simple wing model with adjustable stiffness to lower the control surface dynamic pressure and use the control surface as a tab to twist the wing.
