Application of reduced-order models to the design of adaptive aeroelastic structures

Reduced-order models of potential-flow aerodynamics have been developed and greatly facilitate the analysis and design of aeroelastic systems in the early design phase. Models capturing 95% of the physics with 5% of the modeling effort can be realized to evaluate various active and passive design considerations. A delta wing model has been developed to determine the most effective locations for transducers required to provide gust alleviation and flutter control. The basic design philosophy will be presented, and both analytical and experimental results will be discussed. Results from this study indicate that a single sensor/actuator pair can be designed to significantly extend the flutter boundary.
