About the project
This project focuses on experimentally characterizing and predicting noise from tip vortex-blade interactions in eVTOL aircraft, addressing a key challenge in reducing noise for urban air mobility. Using advanced techniques like Particle Image Velocimetry (PIV) and hotwire measurements, this study will inform noise reduction strategies in next-generation urban air mobility systems.
This PhD project offers a unique opportunity to contribute to the development of eVTOL (electrically-powered vertical take-off and landing) aircraft—a transformative technology with significant economic potential in the UK. However, noise poses a challenge for community acceptance. Despite extensive research in fan noise over the past fifty years, the noise from tip vortex-blade interactions remains poorly understood, with no existing predictive models.
This project aims to address this gap through an integrated, predominantly experimental approach to understanding and characterizing the noise generated by tip vortex interactions. These interactions are especially significant when propellers operate in hover conditions. Using advanced Particle Image Velocimetry (PIV) and hotwire measurements, this research will characterize the tip vortex, ultimately leading to the development of analytical models for the noise generated by tip vortex-blade interactions.
You will join the Institute of Sound and Vibration Research (ISVR), a globally recognized centre with nearly 40 dedicated staff members committed to advancing research, consultancy, and education in sound and vibration. You’ll be part of an inspiring team in the Aeroacoustic Research Laboratory, focused on understanding, predicting, and mitigating aeroacoustic noise sources. As a member of Rolls-Royce’s University Technical Centre in Propulsion Systems Noise, you’ll work alongside motivated researchers, PhD students, and postdoctoral scholars from diverse backgrounds.
