The purpose of this paper is to outline a unified framework for multidisciplinary wing synthesis. It contains a description of a set of techniques for analysis and behavior sensitivity analysis of actively controlled fiber composite wings, which will facilitate integrated design optimization. Several aspects of structural, aerodynamic, and control system modeling are discussed. Computational efficiency and accuracy of approximations for a rich variety of behavior constraints are examined. The paper lays the foundation for the application of approximation concepts and optimization techniques to practical control augmented aeroelastic wing design.
