Ce travail est une contribution au développement d’un modèle d’aéroélasticité nonlinéaire, destiné à la prédiction de comportement de surfaces souples de faible épaisseur, soumises à un écoulement de fluide parfait. Ce modèle d’interaction fluide-structure intègre un calcul de structure basé sur un modèle de membrane, à un calcul fluide tridimensionnel instationnaire, basé sur une méthode de singularités associée à une méthode particulaire. Les résultats sur un gréement de J80 sont comparés à des essais in situ. This study adds to the development of a non linear aeroelastic model which is destined to predict the behaviour of a thin flexible surface in contact with a flow under the hypothesis of an inviscid fluid. This fluid structure interaction model integrates a structure calculation, based on a membrane model, with a fluid calculation, based on a singularity method associated with a vortex method. The results on a J80 rig are compared to the experiments in situ.
