[en] This paper is part of a study investigating the prediction of the aeroelastic behavior of
aircraft subjected to transonic aerodynamic forces. The main objective of the work is the
creation of Reduced Order Models from coupled Computational Fluid Dynamic and Finite
Element calculations. The novelty of the approach lies in the identification of different types
of Reduced Order Model in different flight regimes. Linear modal models are used in the
Mach range range where the full CFD/FE system is linear and nonlinear modal models in
the transonic flight regime where the CFD/FE system undergoes Limit Cycle Oscillations.
Static solutions of the CFD/FE system are used in order to determine the extent of the
nonlinear Mach number range. The model treated in this work is a three-dimensional wing
in a transonic flowfield.
