• Shafts, discs, spacers, and rotor assemblies
• Casings, frames, and structural housings
• Sealing systems and interfaces
• Structural, Thermal & Life Analysis
• Perform and guide:
• Stress and deformation analysis
• Low-cycle and high-cycle fatigue (LCF/HCF)
• Creep and thermal growth assessments
• Vibration and rotor dynamics
• Rotor dynamics & Bearings Integration
• Support design of rotating assemblies:
• Rotor stack-up and load paths
• Critical speed separation and stability
• Interface with bearing and lubrication systems:
• Bearing selection and integration
• Oil system routing and sealing concepts
• Manufacturing & Industrialization
• Apply Design for Manufacturability (DFM) and Assembly (DFA)
• Define:
• Materials, coatings, and heat treatments
• Manufacturing processes (machining, forging, additive)
• Testing, Validation & Failure Analysis
• Support engine build and test activities:
• Instrumentation definition
• Test readiness and execution
• Configuration & Product Maturity
• Manage design changes in coordination with configuration management
• Support multiple product configurations (e.g., different customer variants)
