Sergi Palleja Cabre

Dr. Sergi Palleja Cabre is a Royal Academy of Engineering Research Fellow at the Institute of Sound and Vibration Research, within the Faculty of Engineering and Physical Sciences at the University of Southampton. He is a member of the Rolls-Royce University Technology Centre in Propulsion Systems, focusing on understanding and modeling propeller installation noise in novel aircraft architectures and noise reduction technologies.

His educational background includes a PhD from the University of Southampton (2017-2020) as a Marie Skłodowska Curie Early Stage Researcher, an MSc in Aerospace Dynamics from Cranfield University (2016-2017), and an MEng in Aeronautical Engineering from UPC BarcelonaTech, Spain (2015-2017).

Dr. Palleja Cabre's research focuses on aeroacoustics, particularly propeller interaction noise in Unmanned Aerial Vehicle (UAV) and Urban Air Mobility (UAM) sectors, fan broadband noise reduction through innovative treatments like 'downstream porosity', and duct acoustics for noise reduction in compact ducted propellers. His work combines fundamental research with practical applications, leading to significant noise reduction technologies including patented approaches.

Analysis of Dr. Palleja Cabre's recent publications reveals a consistent focus on aeroacoustic noise sources and suppression techniques. His research spans propeller noise in UAVs and UAM, turbulence-aerofoil interaction noise, and ducted fan noise. A significant portion of his work investigates Over-Tip-Rotor liners as a noise reduction technology, alongside innovative approaches using porous materials and flexible aerofoil sections.

Dr. Palleja Cabre has received recognition for his research, including:

• 2021 AIAA Aeroacoustics Best Student Paper Award

As an educator, Dr. Palleja Cabre teaches Fluid Mechanics (module FEEG2003), organizes the Boundary Layer Lab, and supervises undergraduate and MSc research projects. He is actively accepting PhD student applications and has been co-supervising research projects since 2021. His research is supported by the Royal Academy of Engineering and Rolls-Royce through the University Technology Centre in Propulsion Systems.

Dr. Palleja Cabre is a member of the Acoustics Group at the Institute of Sound and Vibration Research, collaborating with industry partners like Rolls-Royce to develop noise reduction technologies for next-generation aircraft propulsion systems.
