Student aerospace / mechanical engineering Development and validation of design rules and methods for liquid hydrogen tanks manufactured from CFRP suited for aeronautic and space applications by cryogenic testing. (w/m/d), bachelor thesis / master thesis / student research paper

Das erwartet Sie:

In order to fulfill the ambitious goals in CO2 emission reduction new technical solutions are needed to break the global dependency on fossil fuels in the commercial aviation domain. One way to radically reduce CO2 emissions would be the conversion of conventional propulsion system to a hydrogen based one. A fuel cell powering an electrically driven propeller as well as a hydrogen driven gas turbine are solution approaches currently investigated at several DLR sites. Both approaches require a safe integration of a robust hydrogen storage systems into the aircraft structure. This concerns in particular the challenge to store the hydrogen under liquified conditions (-253°C). Thus, new aircraft’s structural components must be designed and sized in order to withstand the thermal loads implied by this severe temperature conditions on top of the mechanical loads induced by common flight and ground loads. In this context new design solutions are developed at the Institute of Lightweight Systems. Especially Carbon-Fiber Reinforced Polymers (CFRP) are under investigation at our Institut as a promising material for lightweight liquid hydrogen tanks.

This student vacancy offers you the chance to gain first hand work experience regarding the development of lightweight structures under severe thermo-mechanic loading. Your student research paper, bachelor or master thesis will contribute to the research activities at DLR by focusing on the valdiation of design rules and methods by cryogenic testing of CFRP laminates.

The following working steps are planed:

  • Continuous development and application of the Cryo-TMLA Tool (Python)
  • Development and manufacturing of CFRP test specimens with integrated Fiber Optic Sensor, thermocouples, and bonded strain gauges performe cryogenic testing with low-temperature tests using liquid nitrogen
  • Operation of scientific measurement equipment (FOS, strain gauges, ...)
  • Evaluation and validation of calculation results
  • Presentation and documentation of work results
Das erwarten wir von Ihnen:
  • you are a Student from the area of aerospace engineering or mechanical engineering
  • you have profound programming skills, preferably in Python
  • You are familiar with the basics of technical mechanics and heat transfer.
  • ideally, you already have experience in the field of fiber-reinforced polymers and are familiar with classical laminate theory, network theory and CFRP manufactruing.
  • Experience in cryogenic testing and handling of scientific measurment euqipment would be a plus
  • English language skills in both written and verbal communication complete your profile.
