04.2 - Structural Analysis and Design, Structural Dynamics, AeroelasticityNONLINEAR AEROELASTIC REDUCED ORDER MODELS USING MODAL COORDINATESR.R. Medeiros¹, C.E.S. Cesnik¹, E.B. Coetzee, Airbus Operations, United Kingdom; ¹University of Michigan, United States This work presents a reduced order model for aeroelastic analyses of flexible aircraft. Both the structural and the aerodynamic solutions are modal-based, for easy integration with current industry approaches. An example of nonlinear aeroelastic analysis of a complex structure shows the speedup factor and the accuracy of such reduced order models. |
