　　The flutter phenomenon of aeroelasfic system is one of the most important issues in many areas, especially in aircraft structures.An airfoil in the flow field is a typical nonlinear aeroelastic system with both structural and aerodynamic nonlinearities.The aerodynamic flutter is a kind of dynamic instability phenomenon.The research in bifurcation and complex response of such a nonlinear aeroelastic system is an active scientific frontier [1, 2].
