- This paper presents a theoretical model for predicting turbulence–aerofoil interaction noise for arbitrary leading edge geometries. Turbulence–aerofoil interaction is the dominant noise source in modem turbofan engines. This theoretical model is, for the first time, able to predict the radiated noise for complex profiles. This work is being used by the Aeroengine manufacturers: Rolls-Royce, SAFRAN and General Electric, and the Universities of Cambridge and Sherbrook. The theoretical approach has been used to optimize the leading edge profiles to maximise noise reductions.
