Rolls-Royce University Technology Centre in Gas Turbine Noise

The Institute of Sound and Vibration Research at the University of Southampton plays host to the Rolls-Royce University Technology Centre (UTC) in Gas Turbine Noise.

Reducing aircraft engine noise

Reducing aircraft engine noise

The UTC consists over 25 members and undertakes a programme of research in aeroacoustics focussing on developing and improving noise technology, products and processes of application to current and future aircraft engines.

Aircraft noise is generated by multiple sources many of which are associated with turbulent, unsteady motion. All must be reduced to achieve a significant reduction in overall noise.

Our research activities include theoretical, computational and experimental studies of aircraft noise sources. We have particular interests and expertise in the design of acoustic liners to reduce noise radiated from intake and bypass ducts, the development of improved models for fan broadband noise and jet noise, and their integration within whole aircraft noise prediction schemes.

We are also responsible for developing and exploiting advanced measurement techniques for rig and full-scale engine noise tests, and for appraising noise data acquired in industrial test facilities by Rolls-Royce and other industrial partners.
