In collaboration with Rolls-Royce plc, this studentship will be paid a tax-free stipend of approximately £14,500 p.a. for 3 years, plus tuition fees at the UK/EU rate. Position to be filled as soon as possible.

Applications are invited for a PhD studentship in the Propulsion Engineering Centre, Cranfield University, in the field of aero-engine installation performance and aerodynamics.

To deliver the required efficiency gain for the next generation of aircraft engine powerplants there is a need to develop the tools and know-how to allow aerodynamic integration, at a system-level, of the nacelle, LP system, and installation design space for the next generation of airframes. In the development of future aircraft propulsion systems it is expected that the design and performance of the intake, nacelle and exhaust systems will become more important.

A particular area of interest is in the ability to understand the aerodynamic design space and requirements for these components and how more rapid, yet flexible, methods can be used. Previous research at Cranfield University has investigated some of these aspects at varying levels of fidelity. For example, preliminary assessments of the effect of engine position have quantified the potential impact on thrust, drag and net propulsive force for the combined system.

Methods to design and analyse pylons as well as non-axisymmetric exhaust systems have also been developed. Initial assessments of these non-axisymmetric configurations on the installation thrust and drag have been conducted. In addition, ongoing related work has developed design and analysis tools for intake and nacelles and there is an opportunity to further exploit these methods to address aspects of engine installations. The overall aim of the research is to improve the design and aerodynamics understanding in the area of the integration of VHBR aero-engines for future airframes. The research will focus on the exhaust system aerodynamics and performance as well as on the impact at a mission level.
