Abstract
Aerial vehicles called e-VTOL’s (electric vertical take-off and landing) promise to be the future of urban transport of people and products. Companies from different countries study and develop their own models, always prioritizing energy efficiency and aerodynamics. This work presents a CFD analysis of a conceptual e-VTOL based on existing models and/or prototypes. Simulations are implemented using Navier-Stokes equations (RANS) in the Ansys software with the two-equation realizable k-ε and k-w turbulence models; the mesh was constructed of tri and tetrahedral elements passing through a refinement process. The computational solution was prepared for a scaled-model, at lower relative air speeds, around 20 meters per second, consistent with the flight of an e-VTOL. The similarity of the numerical results with some experimental data is discussed, obtaining a good level of coherence between the data. The investigation of the effects of changes in geometry, as well as the proposal of new designs and concepts, are suggested for future e-vtol design.
