PhD in aero-engine aerodynamics

About the Project

This is a fully funded PhD (fees and bursary) in propulsion system aerodynamics in collaboration with EPSRC, Rolls-Royce and Cranfield University. The measurement and evaluation of intake flow distortion is a crucial aspect of powerplant integration, operability and performance. This applies to podded as well as embedded propulsion systems. The standard approach to measure intake flow distortion is to use a relatively small number of total pressure probes ahead of the fan or compressor. It is acknowledged that this level of resolution is insufficient, but it is difficult to improve this using conventional intrusive measurements. Cranfield University has addressed this problem through non-intrusive particle image velocimetry (PIV) to measure the unsteady velocity field. This provides an increase in spatial resolution of about 2 orders of magnitude relative to the conventional total pressure rake and measures the full three-components of velocity.

The aim of the project is to develop, and exploit, an approach to synchronously measure the velocity and total pressure flow distortion. This would be a notable advance in the state of the art and is potentially a key stepping stone in reducing the reliance on intrusive flow field measurements.

The research will focus on the flow distortion that arises in a complex aero-engine intake. This is predominately a hands-on experimental aerodynamics project with the goal of developing an approach to synchronously acquire velocity and total pressure measurements. This will be a major advance on current experimental practice and will enable the assessment of the intake flow distortion in terms of the key elements that are known to affect the fan operability and performance. The project will build on previous successful programmes which have developed considerable expertise in the measurement of intake flow distortion using non-intrusive methods. The research will encompass rig design and development, advanced aerodynamic measurements, instrumentation integration, and advanced aerodynamic post processing for complex unsteady flows. The overall aim is advance intake flow field measurement methods that can be used in aero-engine design and testing.

The main impact of the work will be through Rolls-Royce where it will enable improvements to powerplant/airframe integration, aero-engine testing methods and compressor system operability. Unique opportunities for conference attendance, international workshops and industrial placements within Rolls-Royce are part of the programme.

The work will be conducted through the Rolls-Royce University Technology Centre based at Cranfield which has a strong collaborative history with Rolls-Royce in the area of aero-engine aerodynamics. This programme provides the PhD candidate with an outstanding opportunity to work closely with Rolls-Royce engineers across a range of disciplines for the development of future aerospace technologies and capabilities. During the PhD programme there will be regular reviews and presentation opportunities with Rolls-Royce as well as the chance to attend specialist MSc modules if needed.
