Abstract:

This volume aims to complete the review on the state of the art of unsteady turbomachinery aerodynamics by presenting the state of the art of structural dynamics and of aeroelasticity. The eleven chapters in this second volume give an overview of the subject and reviews of the structural dynamics characteristics and analysis methods applicable to single blades and bladed assemblies. The blade fatigue problem and its assessment methods, and life-time prediction are considered. Aeroelastic topics covered include the problem of blade-disc shroud aeroelastic coupling, formulations and solutions for tuned and mistuned rotors, and instrumentation on test procedures to perform a fan flutter test. The effect of stagnation temperature and pressure on flutter is demonstrated and currently available forced vibration and flutter design methodology is reviewed.
