The German Aerospace Center (DLR) in Braunschweig does research in the fields of aeronautics, transport, space and energy. Located at the Research Airport, DLR continues the tradition of the Deutsche Forschungsanstalt für Luft- und Raumfahrt (DFL), founded in 1936, and employs there about 1100 highly-qualified scientists and engineers.

Since the Icelandic volcano system of Bardarbunga began erupting, concerns about a volcanic ash cloud spreading across Europe and bringing air traffic to a standstill, as occurred in April 2010, have arisen once again. To enable the aviation industry to respond to volcanic ash more flexibly in the future, the German Aerospace Center (DLR) has been developing an improved satellite-supported volcanic ash detection system as part of Project VolcATS (Volcanic Ash Impact on the Air Transport System). DLR researchers are using improved views of the situation to investigate how air traffic management can adapt flexibly to large-scale airspace restrictions caused by volcanic ash
Aircraft engine noise is a socially pressing issue with a wide range of causes. Until now, turbulent fluctuations in the exhaust gas stream have not been fully understood as one of the major sources of noise. Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have now managed to make these turbulent flow structures in the engine exhaust gases visible using imaging laser measurement technology, and they have measured the overall flow behind the engine with unprecedented quality. Future generations of engines will be able to benefit from this new knowledge.
