Investigation of the noise levels produced by electric Boundary Layer Ingesting fans in aircraft

11 September 2024 15:20 - 15:40

The presentation covers the fundamental physics of noise generation, propagation, and perception in electric Boundary Layer Ingesting (BLI) ducted fans, using measurement data from a national wind tunnel aeroacoustics facility in Bristol. It introduces a source decomposition method to analyse noise origins and interactions, essential for developing quieter airframe-integrated (or embedded) propulsion systems in future-generation aircraft.
