Even after 50 years of research and development the location of the dominant noise sources on an aircraft engine is not completely known. This project, sponsored by Rolls-Royce, aims to develop and apply new acoustical source location methods that enable the most significant noise sources to be identified and quantified.
It has long been suspected that the dominant broadband noise sources are located either on the rotor or the Outlet guide Vanes (OGV). This project will develop acoustical methods for use in the gap between them (the engine inter-stage) to establish the relative balance of noise sources between them at different frequencies.
The difficulty with making noise measurement in the duct intake or bypass is the effect of blockage by the rotor and OGV respectively. However, noise measurement made in the engine interstage do not suffer from this blockage effect. This was the motivation for the noise measurements made in recent European projects. However, these interstage measurements suffer from the effects of swirling flow and the near field from the rotor and OGV. The objective of this PhD is to develop further these measurement techniques to enable robust and accurate measurements of the broadband noise due to the rotor and OGV in the absence of the other.
A very good undergraduate degree (at least a UK 2:1 honours degree, or its international equivalent).
Closing date: applications should be received no later than 31 August 2020 for standard admissions, but later applications may be considered depending on the funds remaining in place.
Funding: full tuition fees for EU/UK students plus for UK students, an enhanced stipend of £15,009 tax-free per annum for up to 3.5 years.
