Computational Aeroacoustic Analysis of Propellers
Aviation's aim is a safer, cleaner and quieter aircraft. For short and medium range flights, turboprops are the most convinient choice because of their high propulsive efficiency combined with high speed. However, improvements are needed to comply with the future acoustic emissions certification requirements.
Computational Fluid Dynamics (CFD), coupled with different acoustic methods, is used to analyse tonal and broadband noise spectra of different propeller innovative designs. Installed configurations (model-scale and full-scale) are also studied to investigate the airframe interaction's effects.
This research started inside the framework of IMPACTA (IMproving the Propulsion Aerodynamics and aCoustics of Turboprop Aircraft), a project promoted by Dowty Propellers in collaboration with ARA (Aircraft Research Association) and the University of Glasgow.
