On the Influence of Vortex Deformation on Wake Encounter Hazard

Kurzfassung

The paper outlines achievements of research on the influence of vortex deformation on wake encounter hazard. The investigation was performed in the framework of the DLR internal project “Weather & Flying” between 2008 and 2011. Various simulations were carried out in order to quantify the influence of vortex deformation and to find metrics for a hazard assessment. For the investigation piloted simulator studies and in-flight simulations with the DLR research aircraft ATTAS were performed which are described in this paper.
