An Experimental-Numerical Investigation of the Wake Structure of a Hovering Rotor by PIV Combined with a Γ<sub>2</sub> Vortex Detection Criterion

The rotor wake aerodynamic characterization is a fundamental aspect for the development and optimization of future rotary-wing aircraft. The paper is aimed at experimentally and numerically characterizing the blade tip vortices of a small-scale four-bladed isolated rotor in hover conditions. The inv...
