Scientists at DLR Göttingen have achieved a world first – showing the deformation of an aircraft propeller blade during flight. They have developed a special camera that can resist the enormous forces exerted during rotation. Their findings could not only help to improve aircraft propellers, but also helicopter rotors and wind turbines.
The AISat satellite will receive Automatic Identification System (AIS) signals transmitted by ships while it orbits at an altitude of 660 kilometres. Its helical antenna will be pointed towards Earth and will locate ships, especially in high traffic areas like the German Bight.
How the world looks from the perspective of a propeller. The background rushing past is the world appearing to revolve. In reality, the propeller rotates more than 2000 times per minute – and with it a new camera system created by DLR researchers at Göttingen. Thousands of recordings have enabled them to make deformation of propeller blades in flight visible for the first time.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the US corporation Teledyne Brown Engineering, Inc. (TBE) signed an agreement to install and operate the imaging spectrometer DESIS (DLR Earth Sensing Imaging Spectrometer) on board the International Space Station (ISS). DESIS is a hyperspectral camera that records image data using an array of up to 240 closely spaced channels, covering the visible and near infrared portions of the spectrum (450 to 915 nanometres) with a ground resolution of approximately 90 metres.
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. Unlike conventional kerosene, produced using petroleum, the alternative fuel is based on resources that are available in almost unlimited quantities and could therefore make a significant contribution to sustainability and supply security within air transport. The project partners include the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), ETH Zürich, Bauhaus Luftfahrt, Shell Global Solutions and the consulting firm ARTTIC.
The Rosetta mission to Comet 67P/Churyumov-Gerasimenko was launched 10 years ago. Up until then, the comet lander Philae still had no name. In this video, Serena Olga Vismara tells the story of how she named the comet lander in 2004 when she was 15 years old and how she became a Space Engineering Student at the University of Milan - where she will finish her studies in November 2014, exactly when Philae is scheduled to land on the comet.
A first: DLR German Aerospace Center scientists use 3D camaras on a flight campaign in the Annapurna section of the Himalayas in north-central Nepal.
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. For the first time, they flew to the summit of Mount Everest, 8848 metres above sea level, in a motorised glider – taking with them a special 3D camera, the Modular Airborne Camera System, or MACS. This innovative camera system, developed as part of DLR's focus on technology for security, has been designed to provide the data required to produce a remarkably precise 3D model of the Nepalese Everest region with a resolution of down to 15 centimetres. These images will help improve forecasts of landslides and floods resulting from the outbursting of glacial lakes.
"It´s the first time we do anything like that. The environment is totally unknown." (Andrea Accomazzo, Spacecraft Operations Manager)
Among the most fascinating projects in the exploration of the Universe is the European Space Agency's Rosetta mission, launched in 2004 to investigate the comet 67P/Churyumov--Gerasimenko. For the first time, a spacecraft will follow a comet as it approaches the Sun and land on its nucleus.
This highlight of the mission will take place in November 2014, when the small, autonomous daughter craft, Philae, lands on the comet itself. Philae was designed and built by an international consortium led by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). DLR also runs the lander control centre which is preparing for and overseeing the difficult task of landing on the comet, a feat never before accomplished.

This impressive video takes us on a virtual flight over the mouth of the Kasei Valles region. Earlier in the planet's history, enormous amounts of water flowed through the Martian highlands, sculpting these valleys and leaving its trace in the landscape.
What has a certain SANDRA to do with a digitally networked sky? And why do we consider a research flight that does not even take off newsworthy? Where exactly does the noise emitted by aircraft come from and how can it be reduced? How does an astronaut prepare for a six-month stay on the International Space Station, ISS ? The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) 2013 annual film has the answers.
From the wide variety of projects in 2013, we again chose a few exemplary ones -- SANDRA, for instance. Of course it is not a person, but the eponymous flight experiment carried out on DLR's Airbus A320 'D-ATRA' research aircraft. Its acronym 'Seamless Aeronautical Networking through integration of Data links Radios and Antennas' says it all; the goal is to develop an integral aeronautical communication system. And it's true -- DLR's research aircraft Dornier 728 is stationed in a hangar and, although it will not take off any time soon, it is still in service for science, or, more explicitly, for cabin design and research. A project called LiKab examines the influence of cabin light on aircraft passengers.
What else? The opening of DLR's 3500-square-metre research laboratory :envihab in Cologne, a 'pressure cooker' for materials of the future, a self-parking car, the CeraStorE competence centre for sustainable energy research, wind tunnel research and much more.
But, as said in the beginning, at DLR we only look back to take a look into the future. One of the highlights of 2014 will be 'Blue Dot', the mission of German European Space Agency astronaut Alexander Gerst. On 28 May 2014, he will lift off for a six-month stay on the International Space Station, ISS. In the video, he explains how he prepares for the mission.
On 11 and 12 November 2013, the robots of 10 teams from across Germany competed against one another in the first DLR SpaceBot Cup. The Supercrosshalle in Rheinbreitbach near Bonn was transformed into a planetary landscape with mountains, valleys and a variety of different terrains. The SpaceBot Cup was organised by the DLR Space Administration and supported by the German Federal Ministry of Economics and Technology (Bundesministerium für Wirtschaft und Technologie; BMWi).
On 22 September 2013, researchers from the DLR Institute of Materials Research kept a 16.1-ton truck suspended in the air.
The truck was held only by two steel bolts roughly the same size as a credit card (seven centimetre diameter). The bolts were glued together with a special adhesive.
In 55 videos, researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) facilitate profound knowledge about the fundamentals of CSP (Concentrating Solar Power) project planning, construction, maintenance and optimisation of solar thermal power plants.
Die Filme vermitteln in den einführenden Units die Grundlagen über linien- und punktfokussierende Technologien. Thematisiert wird auch das Solar Resource Assessment, bei dem die solare Einstrahlung an einem Standort bewertet wird, ein wichtiges Kriterium für den Ertrag und damit die Standortwahl von solarthermischen Kraftwerken. Weiterhin werden über optische und thermische Messtechniken für die Ertragssteigerung bis hin zu deren Installation sowie Software zur Kraftwerksplanung und Ertragsprognose alle wichtigen Themen ausführlich behandelt.
