Unsteady Vortex Lattice Method of an Aeroelastic Airfoil with Aileron Structural Non- Linearities
Résumé
This paper presents our recent work on the numerical simulation of fluid-structure interactions of a two dimenional airfoil-aileron configura- tion. The geometrical model is composed of two joint solids: the main airfoil which can pitch (α) and heave (h), and the hinged aileron (β). In a gloabl goal of studying flutter supression using the aileron as nonlinear energy sink, the present 3-dof aeroelastic model has been computed for linear and nonlinear structures.
