DLRmagazine 175
With its nose close to the exhaust jet, the DLR research aircraft Falcon was on the move during the campaign pictured on the cover of DLRmagazine 175. DLR uses such research flights to investigate the influence of sustainable aviation fuels on the climate impact of air traffic. Almost half of this impact consists of so-called non-CO2 effects, which also include contrails. The majority of these have a warming effect on the climate. DLR scientists are also investigating how clever flight route planning can reduce this effect. Other topics in this issue include a DLR start-up that is developing sustainable fuels for spaceflight, an autonomous rail bus and much more.
