Holger Hennings was one of the first people to show an interest in wind power. He followed the failure of the large Growian science project and saw how wind power turbines went on to become a surprising success. Today, Hennings works at the DLR site in Göttingen, making wind power turbines safer and more efficient to operate.
Is it actually true that migrating birds sometimes fly in a V-formation because they can take advantage of the wake flow generated by the bird in front? Frank Holzäpfel laughs.
As they enter and exit tunnels, trains generate pressure waves of varying strengths, depending on their speed. Physicist Daniela Heine, from the DLR Institute of Aerodynamics and Flow Technology, is investigating how these pressure waves can be mitigated.
"Challenges are there to be mastered," Rolf Densing said, grinning. This might well be his life motto, both professionally and privately. Since 2009, the doctor of physics has been the Director of ESA Programmes at the DLR Space Administration, where he is responsible for Germany's involvement in the European Space Agency's research, technology, and infrastructure programmes.
For years, Christine Arlt manipulated the tiniest of particles – 'nanos'. Today, the 32-year-old researcher is Deputy Director of the Institute of Composite Structures and Adaptive Systems at the German Aerospace Center (DLR).
The department's name is lengthy, and what it does is hidden in numbers and tables. It's not exactly an inviting introduction to a scientist who works in the Systems Analysis and Technology Assessment Department at the DLR Institute of Technical Thermodynamics in Stuttgart.
As Janine Schneider walks through the materials testing facility, her eyes light up; it is clear that she is comfortable between the long rows of test equipment. She knew she wanted to work here the moment she entered the premises of the DLR Institute of Materials Research in Cologne for the first time, during a trip there as a student. In our DLR Portraits series, we present the materials researcher.
Erica Barkasz is an early riser; her working day starts at six in the morning in the control room of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) ground station at Weilheim in Upper Bavaria.
As a child, she preferred to watch the first launch of an Ariane rocket on 24 December 1979 instead of eating cookies by the Christmas tree. At 10, her wish was to become an astronaut.
The Arctic, Antarctic, Australian outback or Brazil: Wolfgang Jung spends several months a year in the most remote places on Earth to prepare and launch sounding rockets - also known as rocket probes - into space.
