About the project
This project investigates gust–propeller interaction noise for eVTOL aircraft. Using time-domain modelling, CFD, and experiments validations, it will characterize unsteady aerodynamic loads and validate classical gust-response models. The project aims to predict and mitigate noise in urban environments, supporting quieter, safer, and more efficient eVTOL designs.
This project investigates gust–propeller interaction noise in vertical take-off and landing (VTOL) aircraft and other novel aerial vehicles. Many modern propeller configurations, including fixed-pitch and tilted rotors, operate at low altitudes where flow conditions are highly unsteady. These dynamic inflows generate complex aerodynamic loads and significant noise, posing challenges for both designers and regulators. Understanding the fundamental noise-generation mechanisms under these conditions is crucial for developing quieter and more efficient aircraft.
Classical gust-response models, such as Wagner and Kussner, will be validated and extended to time-domain formulations applicable to modern propellers under a variety of gust conditions. A combination of computational and experimental approaches will be employed to examine the limitations of analytical models and validate predictions. Time-domain models will then link aerodynamic responses to far-field noise, enabling realistic assessment of propeller noise in gusty environments. This research aims to support quieter, safer, and more efficient urban air mobility, informing both design and regulatory guidance, while advancing the understanding of unsteady aerodynamics and aeroacoustics for next-generation aerial vehicles.
