Abstract :
[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/CSD system is linear and nonlinear modal models in the transonic
flight regime where the CFD/CSD system undergoes Limit Cycle Oscillations. Static
solutions of the CFD/CSD 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.
