DLRmagazine 157 - A perfect duet

DLRmagazine 157 - A perfect duet
The cover of the DLRmagazine 157 shows NASA’s DC-8 chasing DLR’s A320 ATRA in the name of science. The joint ND-MAX / ECLIF 2 (NASA / DLR-Multidisciplinary Airborne Experiments / CLIM Impact of Alternative Fuel) research campaign took place in January 2018 in Ramstein.

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. By using special forecasting techniques the scientists from NASA and DLR found just the right region over Germany needed for their flight campaign. The aim of the campaign was to learn how biofuels affect aircraft emissions and contrails. The large quantity of data from the flights in the exhaust stream show how the climate impact of aviation can be reduced. Talking about data: the volumes of data involved in creating digital twins of aircraft components are larger than ever before. Modelling these components is a mammoth task, especially if it must display the entire development process and life cycle of an aircraft. The vision: data packets that move through the development like a digital thread. Tomorrow's aircraft will become more economical, efficient and environmentally friendly.

DLR researchers are looking for and discovering new extrasolar planets far beyond the Solar System. Their discoveries sometimes challenge popular theories – like the unlikely pair in which a giant planet orbits a dwarf star.

If you want to learn more about DLR’s research in aeronautics, space, energy, transport, security and digitalisation – please come by our stand at the International Air Show ILA in Berlin (April 25-29) and the Hanover Trade Fair Industry (April 23-27, 2018).

As always, you can have the DLRmagazine conveniently delivered to your doorstep via the free subscription service.
