Risk-Based Computational Prototyping (Briefing Charts)
Abstract
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.
