DLR, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt) predicts practical ways to achieve dreams of carbon neutral flight. EXACT (Exploration of Electric Aircraft Concepts and Technologies Projects is not an exact depiction of aircraft on the drawing board, but a conceptual program for creating the craft and infrastructure of future flight. The EXACT project is developing a concept for climate-friendly flying in commercial aviation and takes into account the complete life cycle of an aircraft, its components and its fuel. DLR looks beyond the aircraft designs themselves to include sustainable energy sources, powerplant types, and even flight route planning. Goals and Approaches The plan cites the following goals and approaches: “New DLR aviation strategy charts the research path towards emission-free flying. “The energy requirements of upcoming aircraft must be reduced to at least half by 2050. “The climate-neutral aviation of the future requires highly efficient aircraft configurations and an intelligent mix of alternative drive concepts. “Climate-optimized flight …
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 …
