Abstract: The effects of the inlet vortex on engines operating near the ground have been studied for more than 50 years, but the phenomenon is not yet completely understood. A more detailed look into the inlet vortex phenomenon, its origin and the effect it has on ground pressures is investigated using CFD. It is shown that the trailing vortex, which coexists with the inlet vortex, originates on the nacelle surface and is ingested by the inlet. Three different inlet vortex intensity regimes are defined and new correlations are proposed to evaluate the existence of inlet vortices.
Speaker: Mr. Trapp is a propulsion systems engineer at Embraer, with 10 years working with propulsion integration and nacelle systems design on commercial airplanes (ERJ 170 & 190), business jets (Phenom 100 and 300) and currently on the military cargo KC-390. He is a PhD student at the Aeronautics Technological Institute, researching the effects of crosswind on engine nacelles.
