The German Aerospace Center (DLR) and the american National Aeronautics and Space Administration (NASA) have been cooperating in the field of atmospheric research since the end of the 1990s. In aeronautics research, both partners are particularly involved in joint research projects in the areas of air traffic management, as well as low-noise and low-emission flying.
After the flight tests on 16 January NASA DC-8 and DLR A320 ATRA fly together until 2 February 2018 in the joint campaign ND-MAX/ECLIF 2 (NASA/DLR-Multidisciplinary Airborne eXperiments/Emission and CLimate Impact of alternative Fuel). The series of research flights will start from Ramstein Air Base in Germany. The researchers want to investigate more closely how the composition of different alternative fuels influences the emissions and the climate-relevant properties of contrails.
