| Abstract | |
This paper presents a methodology that aims at performing a CFD simulation of a micro unmanned aerial vehicle. The rotors are described by a set of overset near-body grids, whereas the fuselage is represented by immersed boundaries within a Cartesian mesh. A coupling between the two methods is proposed and applied to a complete rotor mounted on a drone arm. Three simulations of increasing geometrical complexity are performed, in order to highlight their respective contribution to the aerodynamics. The hub is found to be responsible for a significant increase in forces with almost no impact on the flow behavior whereas the mounting on the arm changes the wake structure and the noise generation.
