Nathan Moshman and Brian Sobulefsky present research on helicopter noise modeling at the 2021 AIAA Aviation Forum in the Propeller, Rotorcraft and V/STOL Noise Session. The work, entitled ‘Helicopter Acoustics Model (HAM): A Mid-Fidelity Aeroacoustics Model for Predicting Helicopter Noise using Limited Measurements’, demonstrates a proof-of-concept calculation for predicting helicopter noise and identifying parameters in a reduced-order model. The benefit of this approach is enhanced accuracy over the current FAA approved models, while running more efficiently than a full-fidelity calculation.
