At ZARM a payload for measuring accelerations using cold atoms was already integrated. During this project you will use this hardware to:
- Finalize the integration of the payload, apply minor changes to the setup if required
- Implementation of the control software of the payload
- Develop and implement an image analysis tool
- Design of optics for atom interferometry
- Commissioning of the experiment in order to trap atoms

This project aims at creating a simulation environment to ease the simulation of the ascent of sounding rockets using CFD approaches. The simulation will be carried out using ANSYS CFX in combination with the ANSYS ICEM mesher. It shall allow to adapt the geometry of a sounding rocket without the necessity of setting up a new mesh in ICEM.

The objectives and your tasks in this project will be:

Within this project the phase-B development of an Autogenous Pressurization Unit (APU) for the DLR Compact-Sat payload “Future-oriented Research platform for Orbital cryogenic Storage Technologies” (FROST) shall be assisted in strong cooperation with the FROST team. An APU is used to pressurize cryogenic tank systems with evaporated fluid. Within the project planned activities are:

This project aims at a systematic investigation of ultrahigh vacuum technologies for cold atom instruments. Different tools (ANSYS, Inventor, Python,…) and experimental methods (Helium leak detection, absorption spectroscopy, vibration testing, …) will be used to qualify and develop technologies for vacuum seals and oven technologies as alkali-metal source. It shall answer open questions for vacuum systems of cold atom technologies.

The objectives and your tasks in this project will be:

• Read and understand challenges of ultrahigh vacuum systems
• Understand the Theory behind it
• Make yourself familiar with existing simulation setup for structural/thermal simulations
• Adapt existing lab hardware to fill and test ovens
• Test CF-knife edges on dynamic loads (shaker)
• Design and build an oven prototype
• Test oven prototype under operating conditions
• Write and adapt a software for the oven filling facility

A system that was developed for the exact leveling and positioning
of sensitive satellite parts during the AIV process of the
Eu:CROPIS mission.
This experimental device is now to be developed further and
refined to possibly establish a spin-off product.
The main tasks include:
• Development of power, charging and data interfaces
• Development of the basic leveling functionality
• Development of the additional “kinetic sensory” functionality
• Development of the additional “HD camera” functionality
• Development of the firmware for communication and data
interfaces
• Development of the associated API
• Documentation

Phase 0 design of an expander cycle rocket engine for use in future
RLVs and/or upper stages.
This expander cycle engine should be augmented by an electric
pump and provide deep throttling, multi restart capability and green
propellants (IRSU production would be a plus). It should operate in
the lower tens-of kilonewton range and should rely on electrical
motor components that can be acquired of the shelf (COTS) for
example form the high-powered drone sector.
• Propellant choice and performance calculation
• Cycle design
• Trade studies taking available components into account
• Initial rough CAD model (Solidworks licences will be
provided)
• Overall engine performance modelling and estimation
• Documentation of the project
o
Written, models and CAD
Some previous Master thesis with specific pump design models
and data can be used as basis.

To verify developments in the field of novel, flexible, very lightweight photovoltaic applications for space travel, a facility for accelerated, thermal cycling of photovoltaics in a vacuum is to be designed at the DLR Institute of Space Systems in the Mechanical and Thermal Systems department.
