The concept of an electric vertical take-off and landing (eVTOL) aircraft emerged recently with the advanced technological developments in electric propulsion systems and the demand for urban air mobility which can be a countermeasure for traffic congestion in urban and suburban areas. Even though significant research has been done on eVTOL designs, due to the early era of the concept and the wide variety of designs available, there are no specific ways/standards to approach an eVTOL design, unlike the conventional helicopter and aircraft. This research aims to explore the performance evaluation of an eVTOL propeller from the views of both fluid and structural simulations by conducting Computational Fluid Dynamics (CFD) and Fluid-Structure Interaction (FSI) on a wide range of advance ratios. The CFD model used in this research is Reynolds- Averaged Navier-Stokes (RANS) equations with a k-ω Shear Stress Transport (SST) turbulent model. The results provide optimized eVTOL design for the next generation of aircraft concepts to fulfill the aerodynamic performance demands of the world.
