Researchers from DLR based at Göttingen and Braunschweig have succeeded for the first time in visualising the main cause of what makes helicopters so noisy while in the air.
The sound of aircraft engines starting up – an everyday occurrence in many towns close to airports. To help develop quieter aircraft engines, scientists from DLR are going to use contactless laser metrology and microphones for the very first time to investigate the sources of noise inside jet engines and on the main fan.
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.
Researchers at the German Aerospace Center (DLR) in Göttingen have discovered a way to make helicopters more manoeuvrable.
Insects are capable of masterful feats of flying; whenever they witness locusts flying long distances or moths hovering over flowers, aerodynamicists can only marvel.
Modern helicopters could be significantly faster and more manoeuvrable - if aerodynamics did not impose limitations on them. Researchers at the German Aerospace Center (DLR) in Göttingen have now discovered and flight-tested a way to increase manoeuvrability using an idea they got from observing humpback whales.
Can new types of engine make spaceflight easier and more economical? This question is being investigated by researchers at the German Aerospace Center using one of Europe's leading hypersonic wind tunnels, located in Göttingen.
Right in the heart of Göttingen - 236 cubic metres of outer space! The German Aerospace Center (DLR) will now be able to conduct research on electric spacecraft propulsion systems under realistic conditions.
The German Aerospace Center (DLR) and Airbus have flight-tested a new ventilation system for aircraft for the first time, with the objective of improving passenger comfort while saving energy and fuel.
The flight of birds is still largely unexplored; in particular, the movements performed during the beat of a wing and the airflow around the wing are a puzzle to scientists. The German Aerospace Center (DLR), in collaboration with its partners, is addressing question. On 26 April 2011, they will photograph the wing of a barn owl while it is in flight.
