Flutter analysis of a two-dimensional airfoil with cubic non-linear restoring force

Flutter analysis of a two-dimensional airfoil with a cubic nonlinear restoring force in the pitch degree of freedom is investigated. The structural dynamic equations of motion are integrated by a time marching finite difference scheme. Flutter is determined from conditions which give rise to either a divergent or limit-amplitude solution. Case...
