Developpement du Code de Calcul des Parties Perturbations Transsoniques Instationnaires en Tri-Dimensionnel (Development of a Computing Code for Three Dimensional Unsteady Transonic Small Perturbations)

摘要

A direct fluid-structure coupling computing method is presented as an evolution of an existing two dimensional method based on the ONERA flow computation program to analyze aeronautical profiles. The aeroelasticity computations give the frequency-damping of the profile, diminishing the overall computation time. It is argued that with the traditional indirect method, only the first harmonics are used to compute the overall lift, while the presented method eliminates the negative aspects of that approximation.
