Researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) conducting research into the potential of new types of design have crafted novel configurations for future flight. The DRL and BDLI (German Aerospace Industries Association or Bundesverband der Deutschen Luft- und Raumfahrtindustrie) have published a white paper: “Zero Emission Aviation – Emissionsfreies Fliegen” explicating these configurations. Surprisingly, one of their major findings is that “Electric flight enables lighter aircraft with smaller wings and distributed propulsion systems.” Battery weight has caused MagniX and Ampaire to reduce the number of passengers or the cargo loads on conversions of existing airframes. To counter those issues, “An EU research project is investigating the potential for new propulsion systems and aircraft concepts.” Obviously, these new concepts will need to take advantage of advanced materials to lower airframe weight. Hybrids and Hydrogen Thousands of airliners parked in dry desert locations highlight how the COVID crisis has affected air travel. Despite the ongoing interlude …
DLR’s Future Visions
One Size Does Not Fit All DLR (Deutsches Zentrum für Luft- und Raumfahrt or German Aerospace Center) and the German Aerospace Industries Association (Bundesverband der Deutschen Luft- und Raumfahrtindustrie; BDLI) present future visions of electric aircraft. These range from a four-seat hydrogen-powered repurposed Pipistrel that nine years ago won the NASA Green Flight Challenge to large, multiple propeller, medium-range airliners. Their White Paper, “Zero Emission Aviation – Emissionsfreies Fliegen” (unfortunately available only in German) promotes the promise of “energy transition in air transport, with the goal of zero emissions,” and claims this is “possible by mid-century but requires a considerable increase in innovation.” Rolf Henke, the member of the DLR Executive Board responsible for aeronautics research and technology, explains, “The time has come to start a new chapter in aviation. Our white paper shows the path to emission-free flying for the ‘Green Deal’ in aviation, which will lead to new technologies, attractive high-tech jobs, fascinating products and the promotion of …
