Summary The MEGADESIGN project was supposed to investigate the status that hybrid CFD prediction has on accuracy, in a relative as well as absolute sense. Different test cases have been analyzed and their results were compared to requirements specified by aerodynamic engineers. Produced solutions stayed significantly below requested error limits, however, the maximum lift area with flow separation still poses a challenging task. Proposals have been elaborated to improve the physical modeling of the tests, which seem to be the major source of remaining errors.
