Gas Turbine Performance Engineer; GE - Lynn, MA

Description: A Gas Turbine Performance Engineer role is available through Belcan in Lynn, MA. The position focuses on modeling, analyzing, and evaluating aerospace propulsion systems, with emphasis on transient engine performance, operability assessment, and cycle model development using NPSS and other industry-standard tools. The ideal candidate will collaborate on mission analysis, engine modeling, control‑system interactions, and operability evaluations to ensure engines meet safety, performance, and reliability requirements across the operating envelope.

• NPSS Steady State Cycle Model Support
  • Develop, modify, and maintain NPSS‑based cycle models.
  • Generate mission data, process engine data, prepare NPSS inputs, execute simulations, and post‑process results.
  • Validate model outputs through sanity checks, trend analysis, and comparison against historical or test datasets.
  • Convert and update binary cycle model versions; ensure configuration consistency and traceability.
• Transient Analysis
  • Conduct transient performance simulations (start, acceleration, deceleration, throttle changes, altitude/temperature shifts, shutdown events).
  • Analyze time‑dependent behavior of engine parameters and control system responses.
  • Assess transient stability and system margins for safe transitions between operating states.
  • Identify risks such as surge, over‑temperature, over‑speed, and recommend mitigations.
• Operability Evaluation
  • Evaluate engine performance across the full operating envelope, including surge margin management, flameout avoidance, hardware limits, and environmental constraints.
  • Support definition and maintenance of operability margins for steady‑state and transient conditions.
  • Collaborate with controls, systems, and test teams to ensure operability requirements flow down appropriately.
• General Responsibilities
  • Prepare technical documentation and publish results for internal or customer consumption.
  • Support test data correlation, anomaly investigation, and predictive studies.
  • Interface with cross‑functional teams (performance, controls, mechanical design, systems engineering, test, certification).
  • Participate in design reviews, risk assessments, and trade studies.

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related field.
• 2+ years of experience in gas turbine performance, propulsion modeling, aero‑thermal analysis, or a similar discipline.
• Hands‑on experience with NPSS or an equivalent engine performance modeling tool.
• Strong understanding of gas turbine thermodynamics, cycle analysis, engine component behavior, and performance metrics.
• Experience performing both steady‑state and transient engine analysis.
• Familiarity with operability concepts including surge margin, flameout margins, mechanical/thermal limits, and airflow management.
• Proficiency with data analysis tools (MATLAB, Python, or equivalent).
• Ability to interpret engine test data and correlate with models.
• Strong analytical, communication, and documentation skills.
• US Citizenship required.

• Master’s degree in Aerospace or Mechanical Engineering.
• Experience with aerospace propulsion systems at major OEMs or tier‑one suppliers.
• Knowledge of engine controls, FADEC logic, and fuel‑scheduling strategies.
• Experience with additional modeling tools (e.g., MATLAB/Simulink).
• Background in operability analysis, including compressor maps, bleed schedules, and variable‑geometry actuation.
• Familiarity with engine test planning, instrumentation, and post‑test performance assessment.
• Understanding of certification requirements (FAA/EASA) for propulsion systems.
