Journal of Aircraft, 2020•arc.aiaa.orgThe effects of inlet vortices on engines operating near the ground have been studied for
more than 50 years, but without much focus on the trailing vortices. Computational fluid
dynamics is used, on a DLR-F6 modified nacelle, to allow a more detailed look into the
trailing vortices. The different trailing vortex components and regimes are presented, and the
inlet vortices circulation is calculated inside and outside the engine inlet for these different
regimes. The trailing and ground vortex interaction region is shown.
