Abstract
Aeroacoustics plays a crucial role in advancing propulsion technologies for both conventional and emerging aerial systems. This research focuses on rotor noise characterization in hover and ground effect using high-fidelity numerical simulations and theoretical analyses, aiming to develop effective noise mitigation strategies and improve predictive methodologies, particularly for eVTOL applications. While limited to a single rotor configuration, the study provides a foundational understanding of aeroacoustic behavior in multirotor systems within Urban Air Mobility (UAM). As part of NASA’s University Leadership Initiative (ULI), this work integrates computational and experimental approaches to validate numerical methods for rotor noise prediction. High fidelity computational fluid dynamics (CFD) and aeroacoustic solvers are employed to analyze a scaled eVTOL propeller in hover and edgewise flight under both in-ground-effect (IGE) and out of-ground-effect (OGE) conditions. Results indicate that ground reflections amplify lateral noise levels due to constructive interference, while observer locations significantly influence directivity patterns. Additionally, the study examines how wake interactions alter acoustic signatures when the rotor operates in close proximity to the ground.
