Methode de Calcul du Flutter en Presence de jeu Mecanique et Verification Experimentale (Flutter Analysis Method in Presence of Mechanical Play and Experimental Verification)

Abstract

Flutter analysis in presence of mechanical play occurs in the certification of fail-safe linkage of Falcon horizontal stabilizer. The corresponding calculation method has been developed in our ELFINI software, it is based on: -a Finite Element structural dynamics model, - a time domain model of unsteady aerodynamics (Karpel type), - an implicit time integration, - the resolution of play/contact by an algorithm derived from quadratic optimization techniques
