German Defense Minister Boris Pistorius has spelled out a €35 billion ($40 billion) commitment for the military space sector through the end of the decade.
When non-CO2 effects are taken into consideration, the maximum lifecycle reduction in emissions possible with sustainable aviation fuel (SAF) is less than 50%.
The aim of the tests was to measure the microphysical properties of the contrails resulting from direct hydrogen combustion under real atmospheric conditions.
German aerospace center DLR and Deutsche Aircraft have conducted the first measurements of emissions from a turboprop aircraft powered by 100% synthetic fuel.
Sustainable aviation fuel cuts contrails; MTU progresses fuel cells; medical evacuation drone; and vertical-takeoff-and-landing cargo drone in the UAE.
Distributed-propulsion testbed flies; Airbus hydrogen APU demo; uncrewed delivery corridor; another Chinese eVTOL; and Wright’s megawatt-scale electric engine.
