Measured and calculated effects of angle of attack on the transonic flutter of a supercritical wing

Space-time discontinuous Galerkin finite element method for inviscid gas dynamics

“…The discontinuous Galerkin finite element discretization uses basis functions in each element which are discontinuous across element faces, both in space and time. The finite 5 , where…”

“…In order to investigate the capabilities of the space-time DGFEM, as implemented in the flow solver Hexadap, for fluid-structure interaction we simulate the elastic deformation of the AGARD 445.6 wing (Yates et al [5]; weakened wing number 3). The wing is modelled with a simple beam model, described by the Euler-Bernouilli equations, and allows for bending and torsion due to the external aerodynamic forces.…”

“…Cross-sectional material properties are estimated from the experimental data, presented in [5], by tuning the bending and torsional stiffness of the beam such that the mode shape frequencies are comparable to the frequencies of the experiment (see Table 1).…”
