Abstract
The paper shows for steady and unsteady tasks the usage of high-fidelity CFD-CSM interaction. While for steady scenarios CFD is the standard method for nowadays aerodynamic prediction, the level of detail in the structural model is often limited to linear FEM models with, by definition, rigid airfoils. Here the usage of multi-body models with nonlinear body motion and single-body nonlinear structural models is presented. For dynamic applications like flutter prediction, an approach which allows using purely unsteady CFD data, is presented. In this connection the combination of linearised CFD and unsteady data recycling results in a very efficient and accurate unsteady aerodynamic ROM.
