KurzbeschreibungDesigning 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.
LernzielTo 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.
