An entry with perspective
Pöschmann became aware of the MfSI when he discovered a tender for a combined internship with subsequent bachelor thesis on a university -internal information platform. The contact person was Jan Jucknies, Talent Manager of the MfSI, who has been helping to shape the close connection to the university for years.
We are always happy when we actively promote tomorrow’s specialists and can offer you an insight into everyday work after your studies
says Jan Jucknies. You get to know how your learned knowledge is used in practice – and we can position ourselves as a future employer.
Measurements with 6,500 liters per minute
In the center of Pöschmann’s work in the course Physical technology is the high -performance extinguishing turbine MXONE. In the event of a fire, it enables the targeted use of water, foam or water lever from a safe distance with high precision and a throwing distance of over 100 meters. For the next generation of turbine, the student develops software with which operating conditions can be simulated and visualized.
The goal: an application with a graphical surface that calculates the trajectory of the water jet after entering pressure and adjusting angles – including the impact point and crown height. In order for the program to provide reliable results, real measurement data is required.
Practical test in the blue light museum
No sooner said than done: in mid-July representatives of the MfSI and the TH Lübeck traveled to Beuster in Saxony-Anhalt. The terrain of the blue light museum offered ideal conditions – lots of space, a stable water supply and the possibility to carry out 76 measurements with 14 adjustment angles and eight different pressures.
The extinguishing turbine shoots up to 6,500 liters per minute
says Pöschmann. It doesn’t just work on the conventional extinguishing water connection.
Each configuration has been carefully documented- with photo and drone recordings as well as parallel data acquisition.
Despite adverse weather conditions with rain and wind, the first evaluations show promising results: I am in good spirits that I was able to carry out all the derivations that I now need to further analyze the results.
Strong connection between university and practice
Ulf Lezius, professor of measurement and control technology at the TH Lübeck and supervisor of the Bachelor thesis, was also on site at the test day:I am thrilled that Jaro has worked into the matter in this way. It is great to see how research and practice interact with each other and create a result together! This is always exciting for me as an old rabbit in the subject. Minimax and TH Lübeck have been combining fruitful cooperation for several years – I hope that we will expand them together in the future!
