Moshman Research presents Conference Publication at 2021 AIAA Aviation Forum

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.
