Within the Department of Aeroengines, situated at the Institute of Aeronautics and Astronautics (ILR) in Berlin, we are an independent student initiative dealing with the interesting and challenging works on a completely self-developed and built micro gas turbine.
The first prototype of the micro gas turbine was developed in 2007 as part of a project workshop. The current project team deals with the advancement and optimization of all components of the micro engine with the long-term objective of optimizing design, functionality, security and efficiency of single systems and, in consequence, of the entire micro gas turbine. For the ongoing testing of the micro gas turbine, which will eventually evolve into the design of a second generation, a new test rig within the turbine laboratory of the institute is built up.

Micro gas turbines have been used by multiple industries such as the aerospace industry, e.g. as APU, the automotive industry, as stand-alone power generation devices or in the classic field of model making. In the project being presented in this article, a micro gas turbine has been developed which did not exist in that form before.

A unique configuration was aimed for, which could be advantageously used as an experimental test carrier. These goals have been fully achieved leading to an exclusive experimental system for aerospace propulsion. The micro gas turbine has been developed with the intention to deliver thrust which can then be measured by an appropriate sensor system. The measurement, the supervision and the display of thermodynamic state variables, for example pressure and temperature as well as performance data such as thrust, mass flow rate and rotational frequency, present the scope of our research. Only with the assumptions derived from such deliberation can the theoretical knowledge, provided in various lectures, be proven practically in an inimitable way. Exactly in this does the presented project differ from already existing micro turbine engine projects and, nevertheless, resemble at the same time commercially produced turbo machines, which are often steered and regulated electronically with the help of the parameters mentioned above.

Furthermore, multiple possibilities for interesting and trendsetting scientific research are given. Among others, an important aspect for future research projects would be the very low cost portion of the kerosene during operation caused by low fuel consumption as well as the possibilities given by the modular construction enabling a quick variation of single process parameters.

Compared to classical university education all important aspects of modern engineering sciences within the project are mediated in an unconventional form. Due to the independent project work, skills like interdisciplinary cooperation, planning, design, calculation, simulation, choice of material, construction, testing, optimization and not the least economic aspects are trained on behalf of a complex technical problem. These issues are also, besides purely theoretical considerations, of special meaning for the improvement of technical university didactics in the engineering apprenticeship.
