Abstract

The identification of nonlinear aeroelastic behaviors is required for the validation of computational methodologies and the development of reduced-order models. This work presents analysis tools capable of the characterization of transient and cubically nonlinear aeroelastic response behaviors. In particular, wavelet analysis is used to characterize the transition of an aeroelastic response from one fixed point or equilibrium solution to another. The Fourier-based trispectrum is also used to identify aeroelastic cubic nonlinearities. The advantages of using these tools are demonstrated through their applications, along with other analysis tools, to a model that describes observed aeroelastic phenomena of the Nonlinear Aeroelastic Testbed Apparatus (NATA). The use of these tools for the development of reduced-order models is briefly discussed.
