Praktische Blockveranstaltung, die im Simultan-Entwurfslabor „Concurrent Engineering Facility“ (CEF) des DLR stattfindet, wo ein Raumfahrzeug in einem geführten Designprozess konzeptionell entwickelt wird, genauso wie dies in der Praxis und mehrmals im Jahr im DLR durchgeführt wird.
Jede® Studierende übernimmt dabei für eine Woche die Rolle eines Subsystem-„Experten“ für eine der relevanten Positionen im Entwicklungsprozess wie z.B. Struktur, Power System, OBDH, COMMS, TCS, AOCS, Kosten, Risiko. Es erfolgt die Anwendung des DLR Concurrent Engineering Prozesses inkl. MBSE (z.B. Virtual Satellite), Collaborative Engineering sowie teilweise Agile Scrum Design-Methoden.

Currently, a traditional proton-membrane (PEM) electrolyser is used for the production of oxygen and hydrogen on the International Space Station (ISS) as part of the greater oxygen generator assembly (OGA). Due to its numerous malfunctions, unreliability and complex maintenance, the OGA is however not suitable for oxygen production on long-term space missions. In part, this is also because the PEM electrolyser requires an additional centrifuge system to remove the produced gas as the near-absence of buoyancy complicates gas-liquid phase separation. Gas-diffusion electrode systems are currently developed for terrestrial electrolysis systems, as they circumvent gas diffusion obstacles e.g., in simultaneous CO2 reduction and oxygen producing electrolysers. The project focuses on an energetic comparison between the PEM electrolyser system used on the ISS and a gas diffusion electrode arrangement for hydrogen and oxygen production in space environments.

The objective of this master project is the design, manufacturing, testing and validation of a small-scale wind tunnel. The purpose of this wind tunnel is to perform experiments of small wings: where the lift generated by different wing geometries, at different angles of attack is to be measured, and the flow visualized. Additionally you will use numerical methods to compute the theoretical lift force generated by the wings. You will use these simulations to validate your wind tunnel, and to compare the experimental and theoretical results. Thus this project is subdivided into four knowledge areas: (1) Numerical simulations using a (simple) potential flow method (2) Numerical simulations using OpenFoam (3) Measurement techniques and (4) CAD and assembly. It is therefore intended for 4 students with:

In this project students shall implement new simulation approaches for the design of space systems. In this project phase from winter semester 2025 and summer semester 2026 the focus is on a simulation of the hypersonic ascent of a sounding rocket with CFD and potential assistance through AI. The students will work on one of the following topics:
1.) Ablative heat shield implementation on available nose cone models with atmospheric parameters investigation
2.) Training of AI algorithm / neural network on different data sets obtained from a classical CFD simulation

The ZARM institute investigates multiple quantum sensor for sensing of accelerations or pressures, as well as different approaches to provide frequency references.
This project will study different enabling technologies supporting the developments of these quantum sensors and frequency references. Hereby the participants will get a basic introduction into fundamentals of quantum technologies and will subsequently work on one of the following topics:.

• Design and comissioning of a teststand for Partial Pressure determination of Potassium using Spectroscopy
• Design and test of a micro valve for UHV systems

• Introduction to computational materials science, i.e. modeling over length scales.
• Calculations of fundamental material properties (using density functional theory)
• Handling of material databases and basic principles of material informatics
• Thermodynamic modeling based on the CalPhaD approach
