Note (General): Unsteady Navier-Stokes calculations around arifoil/wing are demonstrated. 2D transonic flutter simulations are performed about NACA 64A010 airfoil using not only a diagonal form of Beam-Warming scheme but also a non-diagonal one. The effects of time accuracy of the algorithms on the flutter boundaries are checked by comparing two results. 3D unsteady computations around an oscillating wing in elastic motions are also carried out and obtained results are compared with experimental data. It is found that the diagonal form of Beam-Warming scheme is efficient to predict the flutter boundaries of airfoils in case where the flow is not separated. It is also demonstrated that the present 3D code gives results in agreements with experimental data and it can be used for 3D flutter simulation program in a similar manner to 2D case.
