Enter the fascinating world of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt e. V.; DLR) and help shape the future through research and innovation! We offer an exciting and inspiring working environment driven by the expertise and curiosity of our 11,000 employees from 100 nations and our unique infrastructure. Together, we develop sustainable technologies and thus contribute to finding solutions to global challenges. Would you like to join us in addressing this major future challenge? Then this is your place!

Would you like to become part of our innovation-driven research team and help shape the future of lightweight system? We, the Institute of Lightweight Systems, develop and test new lightweight construction technologies for resource-saving and climate-friendly structures in the aerospace, transport, energy and security sectors. Our vision is intelligent lightweight system construction for an emission-free tomorrow.

What to expect

Rotor blades are designed for 20 to 30 years, but real loads vary significantly by location, meaning some blades last longer while others fail earlier due to unexpected stresses, leading to cost and environmental impacts and requiring reliable design methods. Digital twins are becoming increasingly important, as they allow structural design verification not only on test rigs but also during operation, as demonstrated in the DLR wind farm WiValdi. This work contributes to the development of such a method, aiming to regularly evaluate rotor blade behaviour in the field and estimate the consumed lifetime budget. Measurement data from a blade test campaign and turbine operation are available, and deformation and load states are derived from strain data at multiple blade positions using the PreDoCS tool, forming the basis for the subsequent lifetime analysis.

The activity involves accompanying the project from concept to implementation. Around 10–20 working hours per week are planned within a student job or internship. It can ideally be combined with a project or thesis.

.

 

Your tasks

  • Literature research on existing methods
  • Measurement data evaluation and processing
  • Set up a PreDoCS simulation model of the blade
  • Apply the method using test bench data to recover the loads for validation purposes
  • Apply the method to measurement data from operation
  • Integrate a fatigue method in the loads recovery process and evaluate the exhausted fatigue budget for several measurement time series

 

Your profile

  • Ongoing or completed undergraduate studies in mechanical engineering, civil engineering, energy engineering, aerospace engineering, or a comparable engineering discipline
  • Basic knowledge of composite structures and fatigue analysis
  • Initial familiarity with wind turbines
  • A structured and reliable working style
  • Willingness to quickly and independently familiarize yourself with a new topic, combined with motivation and initiative

We offer

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.

We look forward to getting to know you!
