Master-Thesis in LH2 Valve Development & Simulation perimeter for 1XAD D/F/M

at  Airbus Defence and Space GmbH

JOB DESCRIPTION:

We are looking for a LH2 Valve Development & Simulation Master Thesis Student (m/f/d)
to join us at the Airbus site in OTTOBRUNN in E-Aircraft Systems, part of Airbus X-Labs.
One of the main activities of this group is to work on innovative technology bricks related to
hybrid or full electric propulsion of Aircraft, as well as system integration and testing.
For this thesis you will join the design team to work on pre-sizing and simulating cryogenic equipment
for cryogenic fluid control systems. Extending the knowledge on how to design and
model equipment at low temperatures and with various fluids supports Airbus to develop
its next generation of commercial Aircraft. Your work will contribute to improve the understanding
of flow control equipment in itself and overall system behavior. You will take an important role in dealing
with preliminary system level requirements and translate them into a coherent functional design,
iteratively supported by the creation of an adaptable simulation brick to be used in system simulation
as well as in functional sizing of the equipment.
The thesis is planned to begin in the second half of 2024 for an ideal duration of 6 months.
You will be joining a highly visible, publicly known development project,
helping to build novel tools that will be used in the future development of this technology.

EXPERIENCE LEVEL:

Student

Pre-design and CFD Simulation of a excess flow valve:
- Get familiar with current flow control equipment (literature research) and adapt them to an
application with different fluids and/or at different temperatures + transverse assessment of design principles
- Geometric functional design of the equipment, including preselection of functional components
and relevant design features / dimensions
-Support the development and design of future flow control equipment technologies for
cryogenic applications by creating tools/scripts for future design trades.
- Identification of design drives and sensitivities
- Develop a parameterized tool (e.g. Python, Matlab) to identify the impact of these drivers
on the design. This include the integration of a fluidics database (cryprop, refprop)
- This tool is meant to be used as a baseline for future design trades
- Documentation of the tool (e.g. in form of a handbook)
- Creation of a CFD simulation to validate the assumptions / optimization of the functional

geometry, investigations of the behaviour/ stability under changing input/ output conditions

• Get familiar with CFD-software

• Creation of a CFD simulation to validate the assumptions / optimization of the functional
  geometry, investigations of the behaviour/ stability under changing input/ output conditions

• Run simulations and analyse the results to iteratively improve the design and verify initial
  design assumptions
• Comparative preliminary validation of results based on available empirical data
  (elementary testing and/or available COTS equipment characteristics)
  -Document and present the results of the design and simulation excercise
  Required skills :
  You are preparing a Master Thesis in Germany, in Aerospace engineering or similar,
  and you have the following competences:
• Interest in fluid control technologies and associated simulations
• First Experience with CFD simulations (StarCCM+ is a plus) and 0D/1D Simulations
• First Experience with data analysis and visualization (Matlab, python or equivalent)
• Knowledge of aircraft propulsion is a plus
• Basic skills working with 3D CAD Design (CATIA) is a plus
• Comfortable working in English
