Turbomachinery Mechanics and Dynamics
Designing gas turbines means to translate the aerodynamic and thermodynamic intentions into a system, which is both mechanically sound and manufacturable at reasonable cost. This lecture is aimed at giving a comprehensive overview of the mechanical and design requirements, which must be fulfilled by a safe and reliable machine. Material and life prediction methods will be addressed as well.
- To understand the mechanical behaviour of the mechanical systems of gas turbines.
- To know the risks of mechanical and thermomechanical malfunctions and the corresponding design requirements.
- To be able to argue on mechanical design requirements in a comprehensive manner.
- Introduction, Overview, Engine Classes
