Dr. Kevin Britchford

Rolls-Royce, UK

Kevin Britchford

“Future Noise Challenges from Gas Turbine Engine Compressors and Turbines”


“Kevin Britchford is a Technical Specialist within the Rolls-Royce Noise team.  He has an aerodynamics background having worked in the Rolls-Royce Compressor Aerodynamics Department for the first 15 years of his career.  His PhD research was concerned with the measurement and prediction of the flow in annular S-shaped ducts.  Since moving into aeroacoustics, he has been influential in the understanding of noise mechanisms where the underlying aerodynamics plays a major role in the noise source.  He has good understanding of all aspects of large scale rig and engine noise experiments, including rig and facility design, test planning and operation, aerodynamic and noise instrumentation requirements, signal processing and data analysis, and overall appraisal and interpretation of results.

Kevin is the Rolls-Royce Subject Matter Expert for core engine aeroacoustics, with responsibility for compressor, bleed and turbine noise sources.  In addition, he has some responsibility for dealing with external relations, legislation and environmental matters, and technical management of the Noise team at Rolls-Royce.”

Prof. Dr. Lars Enghardt

DLR Engine Acoustics, Germany

Recent Fan Broadband Noise Activities within the Framework of European Funded Collaborative Research Projects

Prof. Dr. Lars Enghardt is Head of the Department of Engine Acoustics within the Institute of Propulsion Technology of DLR. Lars has been active in aeroacoustics research for over 20 years and currently leads a team of 30 in his department in Berlin. The group is primarily concerned with aeroengine acoustics and his department is broken up into four divisions specialising in: Turbomachinery Acoustics; Numerical and Analytical Prediction, Core Noise and Liners and Flow Control.

Prof. Enghardt has an international reputation in aeroacoustics being a member of X-Noise, the CEAS-Aeroacoustics Specialists Committee and the national focal point in Germany for aeroacoustics. Lars has been involved in many EU funded collaborative research projects and has been full project coordinator of PROBAND, FLOCON and currently TurboNoiseBB, each with approximately 16 partners which include the major players of the European aeroengine industry such as Rolls-Royce, MTU and Snecma.

In 2009 Lars was appointed Chair of Turbomachinery and Thermoacoustics at the Technical University of Berlin (TUB). As University professor, Lars delivers lectures on engine acoustics and is currently supervising 12 PhD theses and 6 master theses on various aircraft engine noise topics.

Prof. Dr. Scott C. Morris

University of Notre Dame, USA

Scott Morris

“A Discussion of Broadband Rotor Noise”

Dr. Morris is a Professor in the Department of Aerospace and Mechanical Engineering in the University of Notre Dame and is Research Director of his recently established Turbomachinery Laboratory. In 2016 NASA Glenn donated the well known Advanced Noise Control Fan Rig (ANCF) to Prof. Morris so that it may continue to be used as a research tool.

As director of research at the Notre Dame Turbomachinery Laboratory, Scott currently directs multiple research projects involving turbomachinery and acoustics. He has helped to design and construct the new turbomachinery laboratory at the University of Notre Dame with a focus on improving components of gas turbine engines for propulsion and power system applications. Lab facilities include a new transonic axial compressor and a high-speed research turbine. Both facilities are single stage rotating experiments that allow for advanced diagnostics and flow control under conditions that are similar to full-scale engines.

Dr. Morris is also involved in the research of aeroacoustics where topics of interest include airfoil-generated noise and vibration, fan noise, and the sound associated with active flow control devices.

Dr. David B. Stephens


David Stephens

“Fan Noise and Inflow Distortion”


David Bruce Stephens is a research aerospace engineer working at NASA Glenn Research Center in Cleveland, Ohio. His areas of interest include fan and propeller noise, duct acoustics, turbulence and signal processing. He has an undergraduate degree in mechanical engineering from Rice University and a masters and PhD in aerospace engineering from the University of Notre Dame. 

The NASA Glenn Research Center in Cleveland, Ohio designs and develops innovative technology to advance NASA’s missions in aeronautics and space exploration. The Acoustics Branch conducts research directed at aircraft engine noise reduction. Areas of research include fan and jet noise reduction for both subsonic and supersonic applications including propulsion/airframe integration effects on noise for future advanced propulsion/airframe architectures.
