In the laboratory for aircraft propulsion components, the basic theoretical knowledge transferred in the lectures can be supplemented by practical knowledge and skills gained on the test bed.
The lecture Fundamentals of Thermodynamics introduces the main equations for calculating the energy of fluid flows and defines key figures for process evaluation. This enables the work transfer of turbomachines installed on the test bench as well as their efficiency to be determined.
Subsequently, the existing heat transfer processes conduction, convection and radiation are treated in the lecture Technical Thermodynamics Fluid Machinery. The laws of these processes are used on the test bench to cool or insulate components of turbomachines by means of specific measures. Finally, the lecture Turbomachines provides examples how to transfer rotational energy to flow energy by acceleration and deceleration or how to use flow energy in order to drive a rotating shaft. Corresponding aircraft propulsion components are available in reduced complexity but with entire functionality on the test bench. Their unique properties and their effects on the engine assembly can thus be simplistically reproduced.
