The laboratory for vehicles of urban mobility takes the university's orientation in the field of mobility into account proportionately. Students of different courses of study have the opportunity here to analyse single and multi-track small vehicles, which are ideally suited for use in urban areas, and to pursue scientific questions experimentally and to deepen their knowledge of the subject matter in a practical way.
Goals and idea
The desire for individual mobility reaches its limits, especially when conventional vehicles are used in conurbations, with regard to the necessary traffic space and the emission values to be observed. For these reasons, it is necessary to develop sustainable city vehicles.
In the laboratory for urban mobility vehicles, a roller test bench in the low power range is available for this purpose, on which very small vehicles with different drive systems (combustion engine, electric motor, hybrid drive) can be examined metrologically. The measurement results can be further processed on the existing PC workstations and vehicle and engine simulations can also be performed.
In the further expansion of the laboratory, it is necessary to procure measuring technology that will enable even more precise statements to be made about emissions and drive efficiency.
Laboratory G214
Thermal test bench
The functional principle of an aircraft gas turbine (Joule process) is represented by a passenger car exhaust gas turbocharger with radial compression and expansion and an optically accessible combustion chamber. The reduced complexity of the exhaust gas turbocharger with known geometry allows very simple calculation of the characteristic map of the radial compressor and radial turbine in stationary operation using the Euler equation. As a result of a variably designed burner insert, the combustion characteristics of various swirl-stabilized atomizer nozzles, such as those primarily used in aircraft gas turbines, can be investigated.
The test stand is operated by a LABWIEW control system. In this connection, the proper operation is also ensured by means of a permanent pressure and temperature measurement as well as optical flame detection. An industrial exhaust gas analysis with determination of the oxygen (O2), carbon dioxide (CO2) and nitrogen oxide (NOx) concentrations in the combustion exhaust gas enables an evaluation of the combustion quality.
In addition to research activities, the experimental test bench offers practical courses for the lectures "Turbomachinery" and "Propulsion Systems" in the Aviation Engineering Bachelor's degree program.
