A fuel blend with 50 percent biofuel reduces soot particle emissions of the aircraft by 50 to 70 percent compared to conventional fuel, according to a study published in the scientific journal Nature. The findings are based on an international flight experiment between NASA, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the National Research Council (NRC) of Canada.
Leading aviation technology in new directions with novel ideas and developing aircraft designs that reinvent passenger flight beyond the sound barrier or that are revolutionarily quiet and low-emission – these are the two challenges that the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with NASA, is tasking students within Germany and the United States.
Zurich airport is divided into two sections by an active runway. This centrally located runway has to be crossed by most of the arriving and departing aircraft. With the 'Rerouting runway 28' project, aircraft will use a new taxiway east of the runway, thereby considerably reducing the number of crossings to further increase safety. But can this new taxiway be operated smoothly?
The alarm clock rings mercilessly at 07:00 sharp. Get up, shower, breakfast! Half asleep after a night that was far too short, we make our way to work in the midst of rush hour traffic and do not feel fully awake until after the second cup of coffee. Does that sound familiar?
When aircraft are in flight, vortices are generated behind them from the wing tips. These are known as wake vortices, and they can have safety implications for following air traffic. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has now tested the improvement of a wake vortex avoidance system in flight tests.
International policy-makers have set ambitious goals to reduce greenhouse gas emissions as part of the Paris Agreement regarding climate change. Monitoring emissions will play a crucial role here. Greenhouse gas sources and sinks need to be investigated as accurately as possible in order to obtain reliable climate forecasts. In spring 2017, the research aircraft HALO (High Altitude and LOng Range Research Aircraft) is set to target carbon dioxide and methane, the two most significant greenhouse gases, with its innovative instruments, acquiring data stretching from Europe to North Africa, which is currently lacking.
Norwegian Air and Eurowings are increasingly targeting destinations outside Europe, while Ryanair is continuing to shake up the German market and is now expanding its position as market leader within Europe.
On 29 September 2016, the HY4 aircraft took off on its first official flight from Stuttgart Airport. The HY4 is the world’s first four-seat passenger aircraft powered solely by a hydrogen fuel cell system. Researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) developed the aircraft's power train and worked on the project with industry and research partners.
Everyone knows this situation with a weather forecast, when the presenter reveals a new Icelandic low on the map. Very soon, they are then often told, the trough of low pressure will reach the mainland and determine the weather for many days in Europe. Small errors often lead to the forecast in Europe being very uncertain for several days, because the system develops vigorously in the 'weather kitchen' over the Atlantic, and that is difficult to capture in weather models.
Reducing aircraft noise over residential areas while saving kerosene – this dual improvement is the aim of a joint research project being conducted by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the Umwelt- und Nachbarschaftshaus (UNH) in Kelsterbach.
Landing is one of the most labour-intensive stages of a flight. To help the pilots produce the lowest possible amount of noise in complex manoeuvres during the approach phase, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has developed the Low Noise Augmentation System (LNAS) pilot assistance system.
What effects do tropical clouds have on our climate? Do they warm up or cool down the atmosphere? What factors do they influence? Even the latest models do not fully understand the effects of these climate-influencing 'clouds'.
In the Situation Centre, an alarm flashes on the screen – a passenger ferry has changed its planned course for no apparent reason. The AIS (Automatic Identification System) signal eventually disappears from the display. By now, all ship-specific information must have been requested and compared in order to quickly clarify the situation and take immediate action.
West Africa is changing. An explosively growing population, massive urbanisation, complex meteorological influences, unregulated deforestation and air pollution modify the composition of the atmosphere, not only impacting human health but also the weather and climate. How bad the problem actually is and how exactly these emissions are changing the region in the long-term is not yet clear. Researchers from the German Aerospace Center (DLR) used the Falcon research aircraft to analyse the tropical air on the West African coast in order to determine its composition and its effect on the clouds’ climate-relevant properties. The measurement flights were part of the five-year EU project DACCIWA (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa)..
For the first time, the number of worldwide flights in June exceeded the three million planned take-offs mark – an increase of 3.5 percent compared to the previous year. This is one of the findings in the latest Global Aviation Monitor.
125 years of aviation comes together in one image. Hamburg Finkenwerder Airport was the scene of a historic encounter between a pair of unique aircraft. A replica of the world's first series-built flying machine by Otto Lilienthal, built by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), met the largest passenger aircraft in history, the Airbus A380.
A replica of the world’s first series aircraft passed its test in the wind tunnel, where scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have now demonstrated the aerodynamic quality of the design by the aviation pioneer Otto Lilienthal.
The Earth trembles, rivers burst their banks and tsunamis destroy coastal regions. Natural and man-made disasters make our high technology society ever more sensitive. The current disaster management systems have the drawback that they cannot be flexibly adapted to the respective situation. Hazards and disasters have a similar course but are nevertheless different. The German Aerospace Center (DLR) has developed a system that takes this into account. PHAROS (Project on a Multi-Hazard Open Platform for Satellite Based Downstream Services) supports crisis managers, operations managers and relief workers in every phase of disaster response. The system is built as an open service platform and can be flexibly adapted to the circumstances at hand. Earth observation data, measurements from sensors, simulation tools and communication technologies are combined in a single platform.
Differing airline strategies are shaking up the range of offers in the low cost flight sector. Instead of continuing to build up their network of flight routes, the airlines concerned have been operating more flights on fewer routes.
Aircraft should normally avoid turbulence and wake vortices. But test pilots and researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have deliberately flown into turbulence during flight experiments designed to test numerical models and a new real-time evaluation method that enables the instantaneous review of aeroelastic stability.
