Abstract: Owls are widely known for silent flight, achieving remarkably low noise gliding and flapping flights owing to their unique wing morphologies,which are normally characterized by leading-edgeserrations, trailing-edge fringes and velvet-like surfaces. We take this inspiration by using wavy leading edge profiles on aerofoils to reduce the fan broadband noise, which is one of the dominant noise sources on an aircraft engine. The main focus of the work is to attempt to reduce the fan noise through the development of innovative leading edge geometries.
About the Speaker: Chaitanya Paruchuri is a Research Fellow at Institute of Sound and Vibration Research (ISVR) at the University of Southampton. He is currently developing a three-dimensional numerical approach to predict and reduce fan noise in aircraft engines, funded by the European Union. Chaitanya obtained his PhD from ISVR in the year 2017 specialized in the field aeroacoustics and master’s degree in 2010 from the Indian Institute of Science, Bangalore. He joined GE-Aviation in 2011 and worked on various methodology development projects for prediction of aircraft noise. His research interests are Fan Broadband Noise, Aeroacoustics and Duct acoustics.
