Julius Schultz

Who are you and what is your research topic?
My name is Julius Schultz and I am a research assistant at the Institute for Dynamics and Vibrations at the TU Braunschweig. I am researching the quantification of uncertainties or uncertainties in mathematical models in the Cluster of Excellence.

Which research question are you working on?
In the cluster area ‘Energy Storage and Conversion’ our colleges from Leibnitz University Hannover develop an energy system model for future sustainable aircrafts. The overall energy model brings together the various sub-models - such as the battery, fuel cell and power electronics - and optimizes the mass and the CO₂ consumption. However, the individual models are very unsafe. It is e.g. completely open about how efficient future batteries will actually be. In addition, the models are only now being developed, but we have to make initial statements and estimates based on preliminary modeling. We now estimate the consequences of these uncertainties e.g. on the calculated savings potential using statistical methods. We also identify the critical models in which uncertainties have a particularly large impact on the overall results.

What inspires you about your research?
In the overall energy model, all threads come together. It is exciting to see what the effects on the overall concept and the savings potential are. I am particularly interested in the fundamental methodical work. There are numerous possibilities in the cluster to back up our methods with data and to apply them to specific problems.

Why is your topic relevant for future aviation?
At the end of the day, together with our colleagues from Leibniz Universität Hannover, we want to make statements about how much one can really expect from the various new low-CO₂ approaches. Specifically, we want to determine reliable bands of uncertainty for the CO₂ saving potential

What is special about participating in the interdisciplinary research network SE²A?
Especially in my research field, that deals a lot with methodological development the interdisciplinary approach of the cluster offers me great opportunities. On the one hand I learn a lot from other disciplines and on the other hand I can explain our methods to our project partners and highlight their benefits. A good example for the interdisciplinary approach of the cluster is the fact that I am also working in a second project: This project focuses on the active load reduction on the aircraft wing. Also in this project we want to analyses the effects of uncertainties and thus determine the reliability of such safety relevant systems. In my opinion this example underlines again the verity of the Cluster!
