This paper describes an on-going research effort demonstrating the concept of tailored aeroelasticity for smart structures. In particular, a wing structure is designed as a force multiplier for control actuation. This 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 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 to lower the control surface reversal dynamic pressure and use the control surface as a 'tab' to twist the wing. Analytical and experimental results are presented that indicate that it is possible to tailor the torsional stiffness of a wing such that the reversal speed is significantly reduced from a low-speed stiffness configuration. The results of this study show where, for this example, use of the tailored structure as a force multiplier in conjunction with the trailing edge control surface may be beneficial.
