Intended learning outcomes

The course aims at giving students an overview of airbreathing propulsion engines with the main focus put on jet propulsion. Having finished the course the student shall

·         Understand various types of airbreathing propulsion concepts

·         Understand how thrust and shaft power are interrelated in various types of propulsion engines

·         Understand and be able to explain the main components of jet engines (fan, compressor, turbine)

·         Be able to perform basic thermodynamic and aerodynamic analyses of these components

·         Know the mechanical design of typical jet engines

Course main content

Airbreathing propulsion is largely relying on turbomachines independent of propulsion concepts (propeller, ducted fan, future unducted fans). Especially for jet propulsion engines, turbomachines play a vital role. The reason is to be found in the unprecedented power density as well as reliability of these machines. In other words, modern air transport would not be possible without having turbomachine-powered propulsion devices in place. The present course gives an introduction into airbreathing propulsion concepts and has a clear focus on jet propulsion and turbomachinery. The aero- and thermodynamic terminology and equations relevant for these machines are discussed extensively. The essential fundamental theory is explained in an interactive and animated way. Additionally, today’s and tomorrow’s need for turbomachines is discussed and the future development and research needs are also elucidated. The principles of various propulsion concepts and their impact on energy usage and consequently the environmental impact are treated. Calculations and laboratory exercises are performed with the aim to understand the physical relationship between the aero- and thermodynamics of the machine as a whole a well as specific components.

The course is conceived such that the students build up a solid basic knowledge that allows them performing simple analyses on these types of machines themselves as well as that serves as foundation for further studies in this field.
