Investigation of Blade Vortex Interaction Noise Reduction with Leading-Edge Serrations Using High-Fidelity Numerical Simulations
Blade Vortex Interaction (BVI) noise primarily occurs in rotorcraft when tip vortices generated by the blades interact with other blades. When BVI noise occurs, it dominates at mid and high blade passing frequency harmonics. To mitigate BVI noise, we employ leading-edge serrations on the OLS rotor b
