An integrated approach to the structure/actuator/control aeroservoelastic optimization of strain-actuated aircraft is presented. The approach is based on structural finite elements and industry-standard panel or linearized computational-fluid-dynamics-based aerodynamics together with modern control modeling and associated aeroservoelastic analyses in the time and frequency domains. It can be used for all types and sizes of aircraft, from small unmanned aerial vehicles to large transports. The paper presents the following: (1) comprehensive integrated design-oriented analysis and sensitivity analysis, (2) parametric studies to assess the behavior of various representative aeroservoelastic constraints in response to variations of aeroservoelastic design variables, (3) the accuracy of approximations and sensitivities used, (4) design synthesis by nonlinear programming/approximation concepts, and (5) demonstration optimization examples. The methodology presented has the potential to lead to best practices regarding the design of aircraft with aeroservoelastic strain actuation or conventional actuation or combined conventional/strain actuation and to shed light on the tradeoffs involved.
