NASA and DLR to conduct joint flight tests on alternative fuel emissions with focus on ice crystals

Green Car Congress

The focus will be on alternative fuel emissions and the characterisation of ice crystals in condensation trails (contrails), using biofuel as an example. The joint research flight campaign has been given the title ND-MAX/ECLIF 2 (NASA/DLR-Multidisciplinary Airborne eXperiments/Emission and CLimate Impact of alternative Fuel).
