Coupling VLM and DG methods for the aeroelastic analysis of composite wings

Abstract. In this work, a novel computational tool is introduced for rapid aeroelastic analysis of composite wings, integrating an aerodynamic Vortex Lattice Method with a structural Interior Penalty Discontinuous Galerkin method. After the mathematical description of the aeroelastic model, some results for a composite wing are presented to investigate the influence of varying lamination angles on the wing displacement, twist, and divergence speed. Validation against commercial software confirms the effectiveness of the approach.
