At the 2014 Berlin Air Show (Internationale Luft- und Raumfahrtausstellung; ILA), the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is showcasing its research results for the aerospace of tomorrow with more than 60 exhibits on the DLR stand (Hall 4), in the Space Pavilion and in the Career Center. DLR's research aircraft and helicopters will be on show in the outdoor display area.
Biofuels provide an opportunity to lower the carbon dioxide footprint of air travel and to reduce the potential climatic effects of particle emissions and enhanced cloudiness by aviation.
From 20 to 25 May 2014, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will be at the Berlin Air Show (Internationale Luft- und Raumfahrtausstellung; ILA), presenting numerous concepts for more sustainable, safer and comfortable air travel. In the outdoor area at the air show, DLR will be exhibiting a number of its research aircraft, including the Falcon 20E atmospheric research aircraft. The Space Pavilion, designed by DLR in collaboration with its partners, will be showcasing the TORO walking robot and a number of current European space missions.
An international group of researchers has succeeded in producing the world's first jet fuel from sunlight, water and carbon dioxide in the SOLAR-JET (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable JET fuel) project.
When in flight, aircraft generate turbulence behind them known as wake vortices, which can affect the air traffic that follows. DLR is currently testing a wake turbulence warning system in flight experiments using its ATRA and Falcon research aircraft.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has entered into an agreement with the US National Aeronautics and Space Administration (NASA) to conduct a series of joint research flights. During the flight tests, which will be headed by NASA, the emissions properties of alternative fuels and their effects on the climate and atmosphere will be studied. DLR will participate with its Falcon research aircraft in the approximately two-week-long air campaign. The start of the joint test flights as part of the ACCESS II (Alternative Fuel Effects on Contrails and Cruise emission) project is scheduled for 7 May 2014. The starting point for the flights will be the NASA Armstrong Flight Research Center in Edwards, California.
To fly once around the world, across continents and oceans – powered by the Sun; this is the unprecedented goal of the Solar Impulse project. The flying venture is expected to take place in 2015, using an extremely lightweight aircraft covered with solar cells and powered by four electrically driven propellers.
Unanswered questions about the formation of clouds and their impact on the climate are currently setting limitations on the validity of global climate forecasts. To make a detailed analysis of the climate effects of natural ice clouds and the vapour trails created by air traffic, the HALO research aircraft embarked on the first of a total of 12 measurement flights on 24 March 2014.
For new, quieter descent procedures, pilots must adhere precisely to a predetermined sequence of actions during the landing phase. DLR has developed a pilot assistance system that optimises landings, making them safer, quieter and more fuel-efficient.
Slower landing approaches by aircraft lead to less noise. How slow, steep and hence quiet a modern commercial aircraft can arrive at a destination airport is determined by the performance of the high-lift system with its retractable slats and flaps on the wings. Another advantage of reduced landing speeds is that shorter runways can be used. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has joined with Airbus, and the European Transonic Wind Tunnel (ETW) in the three-part project HINVA (High lift INflight VAlidation), consisting of wind tunnel experiments, flight tests and computer simulations. The aim is to combine computer models and wind tunnel tests to substantially improve predictions of high-lift performance and hence pave the way for slower and quieter approach flights. In early February, the project performed unique wind tunnel experiments at cryogenic temperatures in the ETW in Cologne. Equipped with laser measurement technology and other advanced measurement systems, the researchers achieved hitherto unknown precision in detecting the flowfield around an Airbus A320 with extended landing flaps and slats under flight-representative conditions. The researchers had constructed a high precision wind tunnel model specifically for the tests, based on flow measurements performed during in-flight tests with the DLR A320 ATRA research aircraft.
A team of German pilots from the Mountain Wave Project (MWP) and researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have achieved a groundbreaking feat around the highest mountain on Earth.
Time and again, Himalayan landslides and flash floods cost the lives of dozens of people in Nepal, sweeping away entire villages and infrastructure like bridges and roads. Until now, the images of this remote region have been acquired by satellites.
Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are driven by the desire to improve life on Earth. Among other things, they are working on aircraft that one day will produce less noise emissions and run on alternative fuels, while their more efficient turbines emit fewer pollutants. But DLR researchers are not simply concerned with improving airborne mobility, they also have their feet firmly on the ground, helping us reach our destinations in fast and green transportation, for instance in electric vehicles. And talking about transport, in May 2014 astronaut Alexander Gerst, is scheduled to embark on a six-month journey on board the ISS, where he will conduct numerous experiments in various fields, including biology and medicine, to name just two, that will contribute to improving life here on Earth. Alexander Gerst's mission – Blue Dot – expresses this desire. Viewed from far away in space, the Earth resembles an azure, vulnerable speck. The Rosetta spacecraft will send a wealth of new data back to Earth as it chases a comet, venturing deep into space during 2014. The European spacecraft will reach its destination, Comet 67P/Churyumov-Gerasimenko, after around 10 years of travel. One of the highlights will be the landing of Philae on November 2014. DLR played a major role in building the craft and operates the lander from its control centre in Cologne.
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.
Clouds can both warm and cool Earth's atmosphere. In current climate models, detailed conditions for cloud cover as a climatic factor are still not clearly understood. There is a shortage of precise measurements on how the water, humidity, ice particles and aerosols that form water droplets are distributed in towering cumulus clouds.
Ideas for the airport of the future arise in Hamburg. On 27 and 28 November 2013, researchers at DLR, together with numerous industrial and university research partners in the Lighthouse Project 'Airport 2030', presented their final results in the Conference Centre at Hamburg Airport.
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.
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.
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.
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'.
