Tracking sound with lasers – DLR noise research for quieter aircraft engines

23. September 2013

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.

The future of electromobility – an interview with Ulrich Wagner, DLR Executive Board Member for Energy and Transport

19. September 2013

How many electric cars will be using Germany's roads in 2020? None of us have a crystal ball and this will depend on a wide variety of factors.

German Aerospace Day: Harvesting energy, a life without traffic jams and a world record attempt

12. September 2013

We all want energy to be available when we need it. During German Aerospace Day, energy researchers at DLR will demonstrate how innovative storage devices can be used to efficiently harness energy.

Asteroid Vesta

Atlas of the asteroid Vesta is online

11. September 2013

On 11 May 2011, the camera on board the Dawn spacecraft acquired its first picture of the asteroid Vesta. Despite its diameter of 530 kilometres, this heavenly body appeared as no more than a white dot in the image – at that time, the spacecraft was still 975,000 kilometres away from its destination.

Philae

German Aerospace Day – Comet lander, parabolic flight aircraft and a centrifuge

5. September 2013

Aerospace research covers a broad spectrum of activities – missions to celestial bodies are just as much a part of it as checking the health of astronauts or experimenting in microgravity on parabolic flights.

German Aerospace Day: DLR presents tomorrow's aeronautics research

30. August 2013

A wind tunnel with icy temperatures; test rigs for combustion chambers to house next-generation turbines spewing fire, DLR's largest research aircraft, the Airbus A320 ATRA: These are just a few of the major high-tech apparatus that the German Aerospace Center (DLR) will present at its main headquarters in Cologne on 22 September 2013. German Aerospace Day has a lot to offer in terms of aerospace research: Four DLR institutes will showcase their work on economical, quiet and safe aircraft.

Radaraufnahme Deutsche Bucht

Wide-angle view from space

30. August 2013

Officially, the German radar satellite TerraSAR-X should have been out of service for over a year and a half – that's how long it has exceeded its intended lifespan. But engineers at the German Aerospace Center (DLR) have switched the satellite, which was launched to space on 15 June 2007, to yet another mode: TerraSAR-X can now record image strips over 200 kilometres wide. "The satellite does so by sweeping this large area in multiple stages, very quickly pivoting the radar beam numerous times across the direction of flight," explains DLR mission manager Stefan Buckreuss. For example, the image of the German Bight shows the Frisian Islands from Borkum to Wangerooge and cities such as Wilhelmshaven and Bremen. This new ‘wide-angle’ mode is of particular interest to oceanographers, who will be able to use it to investigate the tidal range, changes to mudflats, shipping movements, wave patterns, ice floes and wind levels.

From the ISS to Mars

20. August 2013

On 20 August 2013, 12 space agencies, among them the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), published the second version of a Global Exploration Roadmap.

Langarmzentrifuge

Using the centrifuge for space tourism

20. August 2013

The first tickets have already been sold to space tourists – the passengers, however, will not be as fit or healthy as astronauts, but rather people with greatly varying health conditions. This is why scientists at the German Aerospace Center (DLR) and physicians from Witten/Herdecke University have come together to analyse the prevalent risks in a pilot study. Using a long-arm centrifuge, they subject participants to 15 minutes of the forces that space tourists would encounter during takeoff and landing. The aim of the study is to determine the influence of increased gravity on blood coagulation.

Deutsche Bucht

A satellite view of the oceans

20. August 2013

Gazing down from space, satellites have the best view of ice floes drifting, waves swelling restlessly, currents moving dangerously, the spread of oil slicks and the changing positions of ships. For this reason, researchers at the German Aerospace Center (DLR) analyse radar images or use satellites to receive ship signals. Now, DLR is pooling the research work conducted at its Remote Sensing Technology Institute and the Institute for Space Systems within the Research Centre for Maritime Safety in Bremen. DLR has set up additional research centres devoted to security on the oceans in Braunschweig, Neustrelitz and Oberpfaffenhofen

Fuel efficiency with insect protection

Fuel efficiency with insect protection

9. August 2013

A windscreen full of insect remains is a familiar experience on the roads in summer. It is no different on the runway at the airport. On warm days, aircraft sometimes collide with entire swarms of insects as they take off and land. Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are working in partnership with Airbus to investigate how the resulting large-scale contamination disturbs the airflow over new wing designs in particular, thus putting targeted fuel savings at risk. Extremely low-level flights by the DLR ATRA research aircraft over Magdeburg-Cochstedt Airport have shown experts in flow patterns how small flying animals affect aircraft. The aim is to create hi-tech wings that incorporate insect protection for the future.

Greater safety in aviation – detecting turbulence in advance

5. August 2013

Many aircraft passengers are familiar with the phenomenon; the sky is clear and blue, the aircraft is cruising calmly, but suddenly everything is disrupted by temporary turbulence. Passengers frequently experience this as a kind of 'hole in the air'.

Alphasat I-XL – a quantum leap for satellite communications

25. July 2013

Everyday life is dominated by information. Constantly growing volumes of data have to be transported around the globe. Satellite telecommunications play an important role in ensuring that such data reaches its destination reliably.

SOFIA explores the southern sky over New Zealand

18. July 2013

For the first time, SOFIA – the Stratospheric Observatory for Infrared Astronomy, has been deployed to the southern hemisphere. Based at the airport in Christchurch, New Zealand for three weeks, SOFIA will study celestial objects that are uniquely observable on southern flight routes.

Mapheus%2d4

MAPHEUS-4: X-rays in microgravity

15. July 2013

Close to four minutes of microgravity prevailed in the sounding rocket MAPHEUS-4, which was launched on 15 July 2013 at 07:53 local time, from the Esrange Space Center in northern Sweden.

Artificial gravity, stress and a controlled environment

5. July 2013

A short-arm centrifuge spins test subjects at six times Earth's gravity; a hypobaric chamber simulates an altitude of 5500 metres; and in the Psychology Laboratory a shuttle has to be docked with the International Space Station under stressful conditions.

New communication channels in the air

27. June 2013

Internet on the airplane – digital systems are an everyday routine for more and more passengers, but pilots are largely cut off from this development.

DLR delivers satellite images for Indian flood assistance

24. June 2013

Following severe flooding in northern India and Nepal, the Indian government activated the 'International Charter Space and Major Disasters' on 19 June 2013 at 10:30.

MoU

DLR and Dassault Aviation agree on cooperation in aerospace research

18. June 2013

Hayabusa2 mit Asteroidenlander MASCOT

MicrOmega on MASCOT: Preparing to visit an asteroid

17. June 2013

It will be a first: in 2018 the Japanese Hayabusa 2 Mission will feature an asteroid landing and will, for the first time, allow for data acquisition at various points of this kind of celestial body, assisted by MASCOT, the hopping landing craft developed by DLR.
