Reduction of Rotor Noise Using Serrated Blades with Modulated Airfoil Thickness
Previous computational aeroacoustics studies of a hovering ideally twisted rotor demonstrated the presence of new broadband noise sources, trailing-edge vortex shedding (TE-VS) noise and blade secondary vortex interaction (BSVI) noise, yielding high-frequency and mid-frequency noise respectively.
