Aeroelastic Analysis Skill

Purpose

Provide comprehensive aeroelastic analysis capabilities for flutter prevention, divergence assessment, and dynamic response prediction.

Capabilities

• Flutter analysis (p-k, PKNL methods)
• Divergence speed determination
• Control reversal analysis
• Gust response analysis
• Ground vibration test correlation
• Aeroelastic tailoring assessment
• Structural coupling analysis
• Flight envelope clearance documentation

Usage Guidelines

• Validate structural modes against GVT data before flutter analysis
• Use appropriate aerodynamic theories for the flight regime
• Include control system effects in flutter predictions
• Apply required flutter margins per certification requirements
• Consider fuel state and payload variations in analysis matrix
• Document all modeling assumptions and uncertainties

Dependencies

• MSC NASTRAN (SOL 144/145/146)
• ZAERO
• FlightLoads

Process Integration

• AE-010: Aeroelastic Analysis
