Turbine Blade Analysis Checklist
Checklist for turbine blade structural analysis covering loads, stress, dynamics, fatigue, creep and clearance.
Loads
- Centrifugal load at max speed and overspeed
- Aerodynamic pressure from CFD mapped and verified
- Thermal field with cooling passages and coating
Stress
- Root stress including stress concentration
- Aerofoil bending and torsion from combined loads
- Thermal stress at leading edge and through-wall
Dynamics
- Pre-stressed modal analysis at operating speed
- Campbell diagram with engine order crossings
- Forced response at critical crossings
Life
- LCF from start/stop stress range
- HCF from vibratory stress with Goodman correction
- Creep from steady stress and temperature
Clearance
- Radial growth (centrifugal + thermal) computed
- Tip clearance positive with margin
