Ioannis Roumeliotis

Join Cranfield University’s Faculty of Engineering and Applied Science for a fully funded PhD project in the world’s first EPSRC Centre for Doctoral Training (CDT) in Net Zero Aviation. This position focuses on the dynamic modelling of aeroengines during transient and emergency operation, aiming to transform the future of aviation through innovative research and industrial collaboration. The project will develop a novel methodology for modelling the secondary air system (SAS) of gas turbines, capturing changes in thermal and aero-mechanical behaviour and accounting for component displacements from shaft failure events. The new SAS model will be integrated into the Whole Engine Simulation Tool (WEST), enabling simulation of engine operation under fast transient and extreme off-design scenarios. This integration will enhance confidence in simulation results and support the assessment of advanced engine architectures and control strategies, including adaptive control and electrification. As part of the CDT in Net Zero Aviation, you will join a diverse cohort and benefit from modular, cohort-based training, collaborative learning, and active engagement with industrial and academic partners. Training will be delivered across multiple universities and industrial partners, including Rolls-Royce, which is pioneering hydrogen propulsion systems and committed to net zero aviation by 2050. The partnership ensures research outcomes are aligned with future aviation applications and provides access to world-class facilities and industrial data for model validation. The research aims to deliver verified tools and guidelines for ultra-efficient engine designs, optimizing performance and operation. Accurate prediction of operating line excursions during acceleration and deceleration will unlock designs with reduced surge margins, improving fuel burn and engine life. The project will also enable assessment of new control strategies, such as variable pitch fans and guide nozzles, potentially reducing fuel and maintenance costs. The ability to model engine behaviour at the boundaries of the operating envelope will lower development cost, time, and risk for new engines. Students will gain expertise in numerical methods, performance engineering, and engine operation, preparing them to act as effective points of contact between specialists in mechanical engineering, turbomachinery, aerodynamics, control, software, and system design. Close collaboration with Rolls-Royce will strengthen transferable skills in technical communication, research management, and stakeholder engagement. Benefits include attendance and presentations at international and national conferences (expenses covered), modular training in technical, research, professional, and personal development, a minimum of 3 months fully funded industrial placement, industrial supervision and mentorship, and access to over 40 partners in the aviation sector. Entry requirements: Applicants must hold a first or second-class UK honours degree or equivalent in aerospace engineering, mechanical engineering, physics, mathematics, or related fields. Knowledge in fluid mechanics, thermodynamic cycles, or numerical analysis is beneficial but not essential. Determination, curiosity, and willingness to learn are valued. Alternative qualifications, industry experience, and diverse backgrounds are encouraged. Flexible working arrangements and tailored support are available for underrepresented groups, mature applicants, carers, or those returning to academia after career breaks. Funding: Sponsored by the EPSRC CDT in Net Zero Aviation and Rolls-Royce plc, this opportunity provides a fully funded 4-year PhD with a £25,183 tax-free annual stipend, plus additional funding for conferences, training, and industrial placement. Open to both Home and Overseas fee status students, with limited studentships for Overseas students. Application deadline: 3 June 2026. Interviews will begin during the application period due to high demand. For further information, contact Prof Ioannis Roumeliotis at [email protected]. Apply online as soon as possible.
