Larger and more powerful engines are making flying more efficient. These gigantic main engines take up more space on the wings of modern passenger aircraft. However, they influence the flow over the wing surface and reduce lift.
NORAH (NOise-Related Annoyance, cognition, and Health) is the largest European-level study on the effects of air, road and rail traffic noise. The results have recently been released by the Environment and Community Centre (Umwelt- und Nachbarschaftshaus), a subsidiary of the German state of Hesse and part of the Forum Airport and Region (Forum Flughafen und Region).
Europe is home to some 450 airlines, 700 airports and a world-leading aviation industry. For 15 years, the Advisory Council for Aviation Research and innovation in Europe (ACARE) has been bringing together the foremost commercial and scientific representatives in the European aviation industry to jointly develop guidelines for European aviation research.
With the project for the HY4 four-seater aircraft, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is taking another major step towards making zero-emission flying a reality – the HY4 will be the world's first four-passenger aircraft powered solely by a hydrogen fuel cell battery system.
The Air Traffic Management Institute (ATMRI) of Nanyang Technological University (NTU) in Singapore was officially inaugurated on 20 August 2015. An air traffic simulation centre forms the core of the new institute.
Alternative fuels have the potential to support the environment- and climate-friendly developments in air transport. At present, global air traffic contributes towards almost five percent of global warming. In addition to the greenhouse gas carbon dioxide, condensation trails and the resulting cirrus clouds lead to a significant climate impact.
Over 60,000 guests visited the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Cologne-Porz site on 20 September 2015 for German Aerospace Day. DLR and the European Space Agency (ESA), together with their partners, exhibited current research projects and missions in the fields of aeronautics, space, energy, transport and security.
From 9 September 2015, test flights are taking place on three consecutive days in a simulated disaster scenario as part of the EU's 'Driving Innovations in Crisis Management for European Resilience' (DRIVER) project. Harrowing scenes are being simulated in Braunschweig on those days. A major flood has covered a wide area around the Tankumsee, a lake near Gifhorn; surrounding roads are also affected and people are stranded in the water.
The International Aviation and Space Salon MAKS 2015 is being held in Zhukovsky, near Moscow, from 25 to 30 August 2015. This is the sixth time that the German Aerospace Center (DLR) is exhibiting at the biennial Russian aerospace exhibition. With an exhibition space of 100 square metres, DLR will be presenting its concepts and technologies for the space and aeronautics of tomorrow. DLR satellite technology is the main focus of the exhibit.
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.
A tangle of treetops and branches, through which just the occasional clear area provides glimpses of the trunks and roots growing below. Whether it is woodland with German spruces or a tropical rainforest, very few sensors are able to see through this green carpet and clearly visualise the underlying structures. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is developing radar technology that, for the first time, will enable a three-dimensional visual representation of forest areas from the roots to the crowns.
Collaboration between them is already a reality, but with the signing of a framework cooperation agreement on 9 July 2015, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the National Research Council of Canada (NRC) have now strengthened their cooperation. Current research projects will be extended in the next five years – for example, in the area of alternative aircraft fuels – and new cooperation projects will be embarked upon to facilitate, among other things, uncrewed aerial vehicles (UAV) and aircraft cabin research.
The US aerospace agency NASA and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have signed two agreements on further scientific cooperation in the aeronautics sector. Both partners want to work together on the research topics of aircraft noise simulation and the improvement of helicopter aerodynamics.
Under the catchphrase 'Knowledge for Tomorrow', the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is presenting its technological innovations in aerospace at the Paris Air Show. The 51st Air Show in Paris, one of the largest and most important aerospace exhibitions in the world, provides an exciting platform for leading representatives of the industry.
Aircraft and vehicle manufacturing are becoming increasingly dependent on structures made of fibre-reinforced polymers (FRPs). The reason for this is the advantageous properties of these high-performance composites – they exhibit high stiffness and strength, but are low in weight.
For accurate weather forecasts and improved climate models, it is crucial to capture data about the winds over the North Atlantic as precisely as possible. Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have developed a prototype of a wind lidar (light detection and ranging) that is scheduled for deployment on a new European Space Agency (ESA) weather satellite in late 2016.
The Greenland ice sheet is, in places, more than three kilometres thick and a crucial feature in climate modelling. Scientists of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with colleagues from ETH Zurich (Eidgenössische Technische Hochschule Zürich), are currently conducting tests of new radar imaging methods in a research flight campaign over Greenland initiated by the Microwaves and Radar Institute in cooperation with the Danish Defence Acquisition and Logistics Organization (DALO).
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Center for Satellite Based Crisis Information (Zentrum für satellitengestützte Kriseninformation; ZKI) is providing relief organisations in Nepal with reference maps of the Kathmandu region.
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.
Aviation and the impact it can have on the climate can be integrated into international climate protection protocols. This would enable significant reductions in climate-related emissions and associated impact, with a modest effect on the demand for air transport.
