Keywords: approximate boundary conditions, Cartesian grids, flutter, Euler equations

The approximate boundary conditions are used for solving the Euler equations coupled with aeroelastic equations for airfoil. An unsteady transonic case of NACA64A010 is first calculated to validate the solver. Finally, flutter boundary of Isogai wing model is presented and compared well with the relevant results in the references.
