Application of 0-1 test for chaos in wind tunnel aeroelastic experiments of an aluminum flat plate

Abstract

© Universal Technology Corporation, 2018.Nonlinear aeroelastic phenomena are continuously investigated in aeronautical researches. The nonlinearity nature can be aerodynamic or structural. This work will investigate aeroelastic nonlinearities in a very flexible wing. A flutter analysis is proceeded in order to evaluate the error between the computational results and the experiment. Since the linear flutter theory considers small disturbances, nonlinear phenomena are expected. Both wind tunnel and computational experiments time series shall be analyzed and the evaluation if the system presents chaotic behavior will be performed through the 0-1 test.
