We are developing computational methods that will enable the computational design of air vehicles accounting for inherently nonlinear dynamic behaviors. These behaviors fall into two categories: behaviors that are beneficial for vehicle operation, such as could be observed for micro air vehicles propelled by wing flapping (e.g., a productive energy transfer between the unsteady vortical flow produced by a flapping wing and the associated nonlinear deformation of the wing), and behaviors that constrain vehicle operation, such as in the dangerous limit-cycle oscillation of large aircraft. In either case, the design space is large and the analysis multi-disciplinary. We have investigated different ways of computing sensitivities of vehicle dynamics to a large number of design variables, compressing the computation using model reduction, and assessing the impact of variability on the reliability of the system.
