Summary
We consider the two-dimensional (2D) panel flutter problem, i.e., a 2D flow over an one-dimensional (1D) plate, with the objective to study the influence of structural nonlinearities and shear deformation on the aeroelastic solution. Preliminary results of numerical simulations of linear and geometrically nonlinear classical plates in transonic Euler flows are presented. We apply a loose fluid structure coupling scheme where we use the DLR FLOWer code to compute the flow field and a modal Galerkin method to compute the plate deformation. An algebraic grid deformation algorithm to adjust the fluid grid to the deforming panel surface is presented.
