Modern aircraft engines have an important role in the worldwide movement of people and goods. Aircraft are an integral part of our modern infrastructure and require highly efficient and powerful engines to operate profitably. In order to meet these requirements, a deep understanding of aerodynamics and thermodynamics in the various aircraft engines is required.

The lecture Luftfahrtantriebe I gives a first insight into the topic of aircraft engines. The focus is on the basic function and design of the single-shaft jet engine and its components. Due to the analytical character of the lecture, the physical dependencies between the individual engine components are shown in a comprehensible way and the most important parameters of the engine design and engine recalculation are derived. Simplified analytical calculation methods are used to determine important targets for the engine, such as thrust or specific fuel consumption in the first order of magnitude. In addition to analytical methods, numerical calculation methods currently used in industry are also presented for comparison purposes. In the course of the lecture you will also acquire first skills in handling the common gas turbine performance software GasTurb.
