Job Description:
As the Thermal Compression Systems Fellow and Subject Matter Expert specializing in aerospace engines, you will be responsible for the design, analysis, and optimization of thermal management systems within aircraft gas turbine engines. Your role will involve ensuring efficient heat transfer, thermal protection, and temperature control of compression system components to maintain optimal performance and reliability under both normal as well as extreme operating conditions.
Key Responsibilities:
Heat Transfer Analysis: Oversee heat transfer analysis and design to predict thermal loads and temperature distributions within compression system components such as compressor blades, vanes, disks, casings, and ducts. Evaluate convective, conductive, and radiative heat transfer mechanisms under various operating conditions across the flight envelope.
Cooling System Design: Design and optimize internal and external cooling systems to transport heat from compression system components and maintain them within safe operating temperature limits. Utilize reduced-order empirical analysis tools and computational fluid dynamics (CFD) tools to simulate bleed and coolant flow distribution, heat transfer effectiveness, and pressure losses.
Heat Shielding and Thermal Protection: Specify and design thermal protection systems, including thermal barrier coatings, heat shields, and insulating materials, to protect compression system components from high-temperature environments. Evaluate thermal barrier performance and durability through analytical modeling and experimental testing.
Thermal Management Strategies: Develop thermal management strategies to control temperature gradients and thermal stresses within compression system components. Implement active and passive cooling techniques, thermal baffles, and heat exchangers to optimize thermal performance while minimizing weight, complexity and cost.
Materials Selection: Collaborate with materials engineers to select high-temperature materials and coatings for compression system components, recognizing the importance of factors such as thermal conductivity, thermal expansion, oxidation resistance, and mechanical properties to ensure compatibility with operating conditions and longevity.
Transient Thermal Analysis: Analyze transient thermal behavior of compression system components during engine start-up, shutdown, and transient operating conditions. Evaluate thermal response times, thermal inertia effects, and thermal cycling fatigue to ensure component durability and reliability.
Testing Support: Provide guidance and support for thermal testing of compression system components and assemblies in laboratory and engine test environments. Analyze test data to validate thermal models and refine design methodologies.
Risk Assessment: Conduct risk assessments to identify potential thermal issues such as hot spots, thermal gradients, and material degradation. Develop risk mitigation plans and collaborate with aerodynamic, structural, and materials engineers to address identified risks.
Documentation and Reporting: Prepare technical reports, design documentation, and presentations to communicate thermal analysis results, design recommendations, and project status to internal stakeholders and customers. Furthermore, develop and maintain Standard Work documentation to meet all thermal requirements, including knowledge capture from simulation or testing.
Training: Provide guidance and hands-on training to lesser experienced personnel in the application of analytical tools, interpretation of simulation or testing results, and in the balanced decision-making required to field a successful compression system design.
The listed responsibilities are not exhaustive and may evolve based on skill level, proficiency, and overall performance.
Qualifications:
Bachelor's and preferably Master's, or Ph.D. degree in Aerospace Engineering, Mechanical Engineering, or a related field.
15+ years of experience with engineering thermal sciences, heat transfer, and fluid dynamics for gas turbine engines from a large OEM or supplier.
Strong proficiency in thermal analysis software (e.g., ANSYS Icepak, Siemens Simcenter) and CFD tools (e.g., ANSYS Fluent, Siemens STAR-CCM+), and in leveraging them to drive design decisions.
Proficiency in CAD software (e.g., CATIA, Siemens NX).
Experience with thermal analysis and design of compression system components for gas turbine engines is highly desirable.
Familiarity with high-temperature materials, coatings, and thermal protection systems used in aerospace applications.
Excellent analytical skills, attention to detail, and ability to work effectively in a multidisciplinary team environment.
Joining our team as the Thermal Compression Systems Fellow and Subject Matter Expert offers an exciting opportunity to contribute to the development of advanced aerospace engine technology, ensuring optimal thermal performance and reliability of compression system components in demanding aerospace applications.
