Compressor Aerothermal Engineer II EDGE Group PJSC

Aerodynamic Design & Stage Performance

• Design and optimize compressor airfoils, stators, and rotors for each stage to meet aerodynamic performance targets.
• Define and develop the flowpath geometry, including hub and shroud contours, blade stacking, and 3D shaping.
• Analyze and manage stage loading, incidence, diffusion factors, and losses.
• Ensure adequate stall margin and choke margin across flight conditions and transient operations (startup, acceleration, etc.).

Thermal and Cooling Design

• Evaluate and define cooling and thermal management strategies for rotor and stator components.
• Assess thermal gradients and expansion behavior to support mechanical and structural integration.
• Collaborate with secondary air systems (SAS) teams to route and balance flow for cooling, sealing, and pressurization.

Simulation and Performance Prediction

• Perform aerodynamic design and analysis using:
• 1D/2D meanline and streamline curvature methods (e.g., Vista, AxStream)
• 3D CFD simulations (ANSYS CFX, NUMECA, TRACE, Fluent, etc.)
• Generate performance maps for stage and module-level behavior.
• Support conjugate heat transfer (CHT) analysis with thermal and mechanical teams.
• Validate CFD models with test data and improve simulation fidelity.

Testing, Validation, and Data Correlation

• Define instrumentation strategies for rig and engine testing (pressure taps, thermocouples, unsteady probes).
• Analyze test data to assess real-world aerodynamic performance and validate design tools.
• Collaborate with test engineers and mechanical teams to resolve discrepancies between predicted and observed results.
• Contribute to performance tuning and operability enhancements based on test feedback.

Integration and Cross-Functional Support

• Work closely with mechanical engineers to ensure aerodynamic and mechanical requirements are balanced.
• Collaborate with structural and vibratory analysts to prevent flutter and ensure aeroelastic safety.
• Support systems and controls engineers on variable geometry (VSVs, VBVs) and operability logic.
• Participate in design reviews, FMEAs, root cause investigations, and engine cycle analysis.

Technology Development & Innovation

• Investigate and implement new aerodynamic technologies such as:
• Advanced 3D blading
• Boundary layer control (bleed, endwall contouring)
• Active or passive stall margin improvement
• Contribute to research on next-generation engine cycles, including geared, hybrid-electric, or ultra-high bypass designs.
