Why join Rolls-Royce?
At Rolls-Royce we are proud to be a business that has truly helped to shape the modern world and are committed to always being a force for progress; powering, protecting and connecting people everywhere.
By joining Rolls-Royce, you'll have the opportunity to work on world-class solutions, supported by a culture that believes individuality is our greatest strength, and all perspectives, experiences and backgrounds help us innovate and enable our high-performance culture.
Position Summary:
This role is part of the Global Mechanical Systems Capability. An Aerothermal Engineer is responsible for the development of Aerothermal capability, both engine delivery from original inception and discussion with the airframers, through NPI, EDP on to Production and Fleet support and technology delivery from TRL1 -7 in conjunction with our strategic partners.
The Aerothermal capability covers gas path aerodynamics, thermodynamics and combustion and relies on skills in Computational Fluid Dynamics at a range of levels of fidelity and testing capability in a range of TRL rigs. Design and capability generation relies also on a knowledge and understanding of the interaction of these components both locally and at an engine level.
What you will be doing:
- Define requirements for aerothermal, ensuring an accurate and complete flow-down and capture of higher-level requirements. This includes system, sub-system and component aerodynamic, thermodynamic and combustion modelling requirements.
- Define concepts for all gas path aerothermal systems that meet requirements and evaluate using appropriate analytical methods to support accurate trades at platform and powerplant level and optimised concept down-select. Concepts delivered should be robust to uncertainties in engine interaction and manufacturing capabilities.
- Integrate gas path aerothermal systems through interaction with all adjacent areas across the organisation to deliver systems are optimised.
- Perform technical analysis of gas path aerothermal functionality at sub-system and component level, using appropriate methods and tools and to a level of fidelity commensurate with each stage of the product lifecycle and the problem being posed.
- Perform appropriate verification and validation activity to ensure that requirements have been correctly met and that all gas path aerothermal related aspects of the powerplant (including numerical modelling) meet expectation. This will include the specification of appropriate test and measurement activity, the calibration of models against measured data, and the quantification of uncertainty.
- Engage in knowledge, Information and Data management for the gas path aerothermal systems, including ensuring adherence to appropriate procedures, technical buy-off, technical report writing, filing and cataloguing of supporting evidence, such as test analysis and numerical simulations. This includes ensuring retention for the relevant time period and deletion once the data or files are superseded or obsolete.
- Provide Production and In-Service support as required, including concessions, drawing alleviation, and technical variances. This may include but is not limited to on-going technical analysis, root-cause-analysis and resolution, and in-service modifications.
- Define and conduct capability acquisition, development and application relating to people, process, methods, tools, knowledge management and technology. This may be conducted internally or externally and may involve securing internal or external funding.
Who we’re looking for:
- Bachelor's degree or Master's in Engineering or regional equivalent qualification, or equivalent experience.
- Strong technical knowledge in mechanical design methodologies and have an understanding of cross-discipline engineering concepts which include but are not limited to manufacturing engineering, aerodynamics, thermodynamics, thermal and mechanical analysis, cost engineering and product definition.
- An ability to apply logical, analytical and innovative thinking on a range of technical problems and make balanced decisions across technical and business parameters.
- Knowledge and experience of product integrity / liability and certification frameworks.
- Membership of a relevant professional body appropriate to region. In the UK - attained/ working towards Chartered status is preferred (and equivalent regional variations).
- Good communication and presentation skills at all levels of the organisation.
Regional Benefits:
- Generous Annual Leave
- Retirement Savings
- Group Life Assurance provides for a lump sum benefit if you die whilst employed by Rolls-Royce
- Group Income Protection provides an income in the event that you are unable to work due to illness or injury
- Your Shares: Matched is a simple way to own Rolls-Royce shares and invest in our future, together. Buy one share, get one free!
Our vision is to ensure that the excellence and ingenuity that shaped our history continues into our future. Our multi-year transformation programme aims to turn Rolls-Royce into a high-performing, competitive, resilient and growing company. Join us, and it can be your future vision too.
Rolls-Royce are committed to being a respectful, inclusive, and non-discriminatory workplace where individuality is valued, diverse perspectives fuel innovation, and everyone can thrive.
To work for the Rolls-Royce Defence business, you will need to hold a Security Check (SC) clearance. Rolls-Royce will support the application for Security Clearance if you do not currently already have this in place.
Due to the nature of work the business conducts and the protection of certain assets we can only progress applications from individuals who are a UK national or, in MoD approved cases, a dual national.
