A spectacular chase in the sky is featured in the DLRmagazine 157: NASA's DC-8 flies behind the DLR research aircraft ATRA and analyses its wake. In order to be able to successfully analyse the effect of biofuels on aircraft emissions, the ideal circumstances included low temperature and humid air as these allow clear contrails to be formed.
The inner values revealed in this year's last DLRmagazine say something about the resilience of components. But as is the case with inner values, they are not readily disclosed. The information is cleverly obtained from the material, by means of three-dimensional digital images of the pores in material alloys, for example.
Without solar and wind power there would be no Energiewende (energy transition). And no energy transition without energy storage. Energy storage materials store the energy and release it when it is needed. Salt could play an important role here. The new and worldwide unique test facility TESIS of DLR will research this.
In the April issue of the DLRmagazine, we are switching on the Sun. This is, of course, artificial and reserved for solar researchers in Jülich! The honeycomb assembly of 149 individually controllable radiator modules achieves 10,000 times the intensity of the solar radiation at Earth' surface.
David the robot is characterised by his clear-cut design. Its purpose is to emphasise his capabilities and avoid any confusion about his limitations, explains his designer, Tilo Wüsthoff. The last issue of the DLRmagazine in 2016 profiles the designer, who has a somewhat atypical job at DLR.
