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.
The effort is based on the prospect that lunar resources can be mined and processed into construction materials at a lower cost than launching them from Earth.
Two-thirds of Europe’s Clean Aviation research projects are focused on more sustainable advanced propulsion technologies for service entry in the mid-2030s.
