About POWERTECH
POWERTECH is a center of excellence for propulsion technologies, specializing in the design, engineering, and manufacturing of combustion engines, expendable turbojet engines, and turbofan engines for a wide range of aerospace, defence, and autonomous applications, including fixed- and rotary-wing UAVs and other advanced platforms.
Job Summary
The Mechanical Engineer II – Secondary Air Systems (SAS) & Whole Engine Modelling (WEM) is responsible for developing and supporting transient thermo-mechanical models that capture the full engine behaviour across mission cycles. The role focuses on building and integrating 2D whole engine models and 1D secondary air systems networks to predict thermal behaviour, component clearances, and structural interactions. Working under senior guidance, the engineer contributes to model development, validation, and application to support design decisions, durability assessments, and risk reduction across the engine program.
RESPONSIBILITIES
Whole Engine Modeling (WEM)
- Develop and maintain 2D axisymmetric thermo-mechanical models of gas turbine engines
- Translate 3D engine geometry into efficient 2D representations, capturing key thermal and structural features
- Implement transient mission profiles, including:
- Startup, acceleration, steady-state, shutdown, and cooldown
- Predict:
- Component temperatures and thermal gradients
- Radial and axial growth
- Rotor–stator clearances over time
- Support correlation of model results with test data and refine assumptions
Secondary Air Systems (SAS) Modeling
- Develop 1D SAS network models including:
- Cooling flows
- Leakage paths
- Cavities and sealing systems
- Define boundary conditions using:
- CFD results
- Empirical correlations
- Test data
- Integrate SAS models with WEM to capture convective heat transfer and transient interactions
Simulation & Tools Development
- Use and support tools such as:
- ANSYS (thermal/FEA)
- NX Thermal / Thermal Desktop
- AxStream or equivalent
- Develop and maintain simulation workflows using:
- Python, MATLAB, or similar scripting tools
- Automate:
- Model setup
- Boundary condition updates
- Mission profile implementation
BASIC QUALIFICATIONS
- Bachelor’s or Master’s degree in Mechanical or Aerospace Engineering
- 4–7 years of experience in:
- Gas turbine thermal modelling
- Secondary air systems or whole engine modelling
- Hands-on experience with thermal/FEA tools and simulation workflows
PREFERRED QUALIFICATIONS
- Experience with:
- Secondary air systems (cooling, sealing, leakage flows)
- Whole engine or system-level modelling
- Exposure to:
- CFD tools and data integration
- Engine testing and data correlation
- Familiarity with performance modelling tools and coupling approaches
