MDO approaches for overall aircraft design based on high-fidelity tools and methods usually go hand in hand with complex computational processes. This is especially the case as the number of the disciplines and the complexity of the disciplinary methods and models increases. Apart from aerodynamic performance analysis of the flexible aircraft using high fidelity CFD analysis, further disciplinary sub-processes were part of three high-fidelity based MDO processes developed and applied within the DLR project VicToria. They were overall aircraft design (OAD) synthesis, loads analysis, structural optimization. In the following, the sub-processes with their simulation models, the analysis and optimizations methods, and the typical responses to be fed into the respective MDO approach are layered out. Furthermore various aspects of the complexity of the simulation models and selected results are presented.
