Informationen und Networking für Outgoings des FB04

Begrüßung aller neuen Studierenden des Fachbereichs Produktionstechnik - Maschinenbau & Verfahrenstechnik (FB04)

Informationsveranstaltung zur Planung, Anmeldung und Anfertigung der Abschlussarbeit in den Studiengängen des Fachbereichs Produktionstechnik

Start from 7:45 p.m., please arrive on time. Afterwards there will be a practical fire extinguishing exercise in the outside area behind the SFG-Building, place outside in the Emmy-Noether-Straße. The participants are asked to pay attention to weatherproof clothing and sturdy shoes, because the fire drill takes place outside.

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:

Ziel dieses Projekts ist die Auseinandersetzung mit Stereo-Vision
Kartierungsmethoden für (semi)autonome Mondrover. Relevante
Kartierungsmethoden sollen die Beschaffung des umgebenden
Terrains in Echtzeit kartieren und damit die Entwicklung von
autonomen Navigationsverhalten vorbereiten. Als Testplattform
dient ein Mikro-Rover, der im Projekt SAMLER-KI am DFKI RIC
entwickelt wird. Im Rahmen des Projekts steht der Student in allen
Phasen im engen Austausch mit Projektmitgliedern von SAMLER-
KI und muss seine Designentscheidungen und Designumsetzung
kommunizieren und abstimmen.

As part of the project, a semi-autonomous robot is to be developed
that masters the tasks of the European Rover Challenge, ERC
(http://roverchallenge.eu). The focus lies on several autonomous
and remotely operated tasks like navigation and mapping in a
fictitious Mars mission or soil sampling with a drilling mechanism.
The robot will be tested both in simulation and in reality. Depending
on the requirements of the challenge, existing hardware and
software of the DFKI Robotic Innovation Center can be used or
newly developed.
This is the second year in which we will apply to the ERC. During
the last edition we successfully completed the first phases of the
project as part of a systems engineering bachelor project, but we
did not pass the final selection. Currently, the rover has been
mostly designed (the team can perform any modification though),
and the construction is ongoing.
The students will perform tasks in the field of robotics, such as
intelligent obstacle avoidance or interaction through a robotic arm
with a control panel. Nevertheless, for the team to be successful in
the ERC, other work will be needed. An important aspect to be
considered is the capacity to produce detailed technical
descriptions of the work done and the rationale of the decisions
taken based on the requirements of the project. The evaluations
that lead to the acceptance or rejection of the team are highly
dependent on this. Another important aspect is the team
organization, which has to be comprehensive, resilient, sustainable,
and scalable.
Objectives of the project:
-
Understanding robotics as an interdisciplinary endeavor
involving electrical engineering, mechatronics and computer
science from the technical side but also with crucial
connections to business, communication, and team
management among others.

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
