Researchers at the German Aerospace Center (DLR) are researching a morphing wing trailing edge that can be smoothly transformed into any shape and will make conventional flaps redundant. The flaps on the wings of today’s commercial airliners are actuated via a complicated mechanism. Their arrangement and the resulting gap when they are extended compromises the aerodynamics, increases fuel consumption and contributes to inflight noise. The new technology, on the other hand, is flexible, its movement being based on that of carnivorous plants. This enables the gap between the wing and the flap to be eliminated.
The Aeroliner3000 train concept, jointly developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the Andreas Vogler Studio (AV Studio) architectural practice, is one of the three finalists in the international 'Tomorrow's Train Design Today' competition.
The DLR Advanced Technology Research Aircraft (ATRA) flew at the limits of its capabilities between 16 and 19 March 2015. In a total of four flights, the test pilots flew the specially instrumented A320 passenger jet at extremely low speeds.
Batteries and fuel cells for the vehicles of tomorrow, solar thermal power plants, heat storage and smart rotor blades for wind turbines – there are plenty of opportunities to make the energy supply of the future clean and sustainable.
Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), in collaboration with Airbus, have completed a successful world première – for the first time, they have used lasers to visualise the airflow over the wing of a passenger aircraft in flight. They have developed a method that captures the movement of water droplets streaming over the wing, which reveals the smallest movements of the air. These findings will help optimise future wings to enable slower and quieter approach procedures. Another 'laser flight' is scheduled for 8 January 2015.
Philae landed on a comet just three weeks ago; now, another German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) lander mission has been launched – the Mobile Asteroid Surface Scout (MASCOT) is already on its way to Asteroid 1999 JU3.
Originally scheduled for launch at 05:24 CET on 30 November 2014, the MASCOT asteroid lander will now set off from Tanegashima Space Center on board the Japanese Space Agency (JAXA) orbiter Hayabusa 2 no earlier than 1 December, destined for asteroid 1999 JU3.
Road congestion is a fact of everyday life for many people. A possible solution for the future is expanding personal transport to include aviation. High above the roads, the routes become much more flexible, and travellers can reach their destinations faster.
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.
