Keywords: HALE Flutter Behaviour, Non-Linear Aeroelasticity, Limit Cycle Oscillations

A time simulation of a nonlinear aeroelastic model is proposed as a design/diagnostic analysis tool for highly flexible HALE aircrafts. Large structure deformations and static and dynamic aeroelastic responses are accounted for. Analytical, computational results are presented along with experiments on a high aspect-ratio wing model.
