| Abstract | 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. |
| Objective | 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. |
| Content | 1) Introduction and Engine Classes 2) Rotor and Combustor Design 3) Rotor Dynamics 4) Excursion 5) Blade Dynamics 6) Blade and Vane Attachments 7) Bearings and Seals 8) Gears and Lubrication 9) Spectrum Analysis 10) Balancing and Lifing 11) Couplings and Alignment 12) Control Systems and Instrumentation 13) Maintenance Techniques |
