What You Will Be Doing

• Define requirements for thermo-fluid systems and thermo-mechanical analysis, ensuring an accurate and complete flow-down and capture of higher-level requirements pertaining to each thermofluid system. This includes system, sub-system and component thermofluid, temperature and thermo-mechanical modelling requirements.
• Define concepts for all thermofluid systems that meet requirements and evaluate using appropriate analytical methods to support accurate trades at platform and powerplant level and optimized concept downselect.
• Integrate thermo-fluid systems through interaction with all adjacent areas across the organization so that thermofluid systems are optimized in ways that support optimum deployment of other, complimentary systems and components.
• Perform technical analysis of thermo-fluid system functionality, and temperature and thermo-mechanical analysis at whole-engine, sub-system and component level, using appropriate methods and tools and to a level of fidelity commensurate with each stage of the product lifecycle.
• Perform appropriate verification and validation activity to ensure that requirements have been correctly written and that all Thermofluid related aspects of the powerplant (including thermofluid systems and temperature and thermo-mechanical 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.
• Manage the technical approval of all thermofluid systems and temperature and thermo-mechanical modelling through to certification and / or qualification, including process compliance checking, model auditing and documentation approval and retention.
• Support the product in-service as required. 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.
