This research is jointly sponsered by EPSRC and Rolls-Royce and will form the basis of my PhD thesis. The aim of the work is to develop measurement techniques for broadband aeroengine noise.
Aeroengine noise is a major contributor to community noise annoyance around airports. While there has been a large degree of success in reducing tonal and jet noise from aircraft engines, the problem of broadband fan noise remains. To aid the engineer in the development of future noise treatments it is necessary to have measurement techniques that allow the accurate quantification and characterisation of broadband noise. Of particular interest is the localisation of broadband noise sources within the engine.
This work aims to develop measurement techniques, and in doing so not
only provide useful tools for the engineering community, but also gain
fundamental insight into the nature of broadband aeroengine noise.
