Bifurcation behavior and chaotic dynamics of a three-degree-of-freedom aeroelastic system

In this paper, we combined analytic method with numerical method to investigate complex dynamic behavior in a three-degree-of-freedom nonlinear aeroelastic system of an airfoil with external store. Center manifold and normal form theories are performed to derive the stability regions of the initial equilibrium point and the explicit expressions of the critical bifurcation curves. Stable and unstable Hopf bifurcations appear when the damping...
