→ Overview of Turbomachinery vibration problems
→ Elastic vibration of bladed disks
→ Basic concepts: cyclic symmetry, Inter Blade Phase Angle, TW and SW modes
→ Forced response
→ Unsteady aerodynamic effects
→ Rotor/Stator interaction: Rotating instability, Rotating stall, Surge
→ Campbell diagram
→ Flutter
→ Linearized aerodynamics
→ Aerodamping
→ Stability analysis
→ Influence coefficient method: Travelling wave method
→ Energy method: Eigen-analysis method
→ Mistuned forced response
→ Mistuned flutter characteristics
→ Intentional vs. random mistuning
→ Nonsynchronous vibration
