A 3D flutter of a sweptback wing is numerically investigated by coupling inviscid flow simulations with a bending-torsion beam structure model. The beam model of a 3D wing is a natural extension of a widely used 2D 2-degree-of-freedom structure model and it considerably simplifies the structure analysis. Finite-volume unstructured CFD is used with the aim of applying various configurations in the future. The grid is dynamically deformed in accordance with the wing motion. A truss-analogy is applied to determine the new positions of interior points when the displacements of boundary points are specified. A well-known experiment using the AGARD standard aeroelastic configuration called 445.6 wing is selected for the validation. The developed methods successfully simulated the experimental flutter boundary.
