Rotor-Airframe Interaction Noise: Predicting and Mitigating Noise with Artificial Neural Networks
… effect known as the rotor-airframe interaction noise creates an unsteady deterministic loading noise that excites the harmonics of the blade passing frequency by as much as 20 dB, which meant that the installation effect could produce more noise than the rotor itself. As a result, it was …
