Validation Tools of Nonlinearities Associated With Aeroelastic Phenomena

Abstract

The work performed under Grant # F49620-03-l-0206 included the analysis of a unique database on the hard flutter of a Flexible Semispan Model of a High Speed Civil Transport model. The experiments were performed in the Langley Transonic Dynamic Tunnel. These experiments are unique in terms of the model scaling and characteristics, the range of Mach number and dynamic pressure and the observed phenomena. To date, the analysis of the data performed with the support of AFOSR yielded two journal articles and two conference papers. The abstracts of these articles and their reference numbers are listed in Appendix A Moreover, a new computer code has been developed to identify cubic nonlinearities of any system.
