|Abstract||In this course, an introduction of working principals of aero-engines and the related background in aero- and thermodynamics is presented. System as well as component engineering aspects of engine design are examined.|
|Objective||Introduction of working principals of aero-engines and the related background in aero- and thermodynamics. Engineering aspects of engine design.|
|Content||This course focuses on the fundamental concepts as well as the applied technologies for aerospace application, with a primary focus related to aviation. The systematic evolution of the aircraft propulsion engines, from turbojet to the modern high bypass ratio turbofan, including the operational limitations, are examined. Following the system analysis, the aerodynamic design of each component, including the inlet, fan, compressor, combustors, turbines and exhaust nozzles are presented. The mechanical and material limitations of the modern designed are also discussed. The environmental aspects of propulsion (noise and emissions) are also presented. In the last part of the course, a basic introduction to the fundamentals of space propulsion is also presented.|

Prerequisites of this course are listed under "catalogue data".
|4 credits||3G||A. Zemp, R. S. Abhari|
|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.

|151-0222-00L||Swiss Energy Policy in an International Context||3 credits||2V||R. S. Abhari, M. Ambühl|
|Abstract||We take an interdisciplinary approach at analysing important challenges of Swiss energy policy. In an introductory section, we scrutinise the fundamentals of both energy technology and energy policy. In a second section, we focus on Swiss energy policy and its interlinkages with Swiss foreign policy. Finally, we take a look at possible scenarios for the Swiss and global energy future.|
|Objective||Students will learn about the complex interplay between energy technologies and energy policy and develop an in-depth understanding of Swiss energy policy. |
- Learn how to analyse resource challenges (exemplified by the challenges of the energy supply system) both from a policy and a technology angle.
- Understand the fundamental processes of energy technology.
- Understand the fundamental challenges of energy policy.
- Develop an understanding of the specific energy policy challenges that Switzerland currently faces - taking into account international developments in energy supply.
- Learn the basics of negotiation engineering.
- Learn about the interlinkages between energy policies and long-term development.
- Develop basic skills in scenario-based strategic thinking.
