A ROADMAP TOWARDS ENVIRONMENTALLY SUSTAINABLE AVIATION

B. Loxton, United States

Different industry players and research organizations have recently joined the challenge towards thernemission?free aviation by 2050. Such cooperation is encompassing experiences and advancements inrnvarious technological fields, including synthetic fuels, hydrogen in gas turbines and hydrogen fuel cells,rnrevolutionary gas turbine cycles, electric propulsion systems, hybrid?electric, optimized battery systemsrnand climate?friendly routing. The numerous advantages offered by electric propulsion in particular havernresulted in a dramatic increase in excitement around this concept.rnLower capital cost, lower fuel (or zero fuel) and maintenance costs, decreased noise and air pollution,rnimproved safety, availability and reliability and enabling solutions for unique aircraft design are amongrnthe benefits of this revolution; however, the realization of the full potential for the electric aircraft marketrnwill require significant advances in motor, inverter and battery technology, with focus on optimizing thernvarious concepts at system level and on realizing higher power densities.rnmagniX, established in 2009 as an electric motor R&D company, has designed, developed, and testedrnmultiple electric motor architectures, topologies, and technologies from superconducting motors torninduction motors to axial flux, radial flux, and more, on its mission to lead the commercial aerospace andrndefense industries by providing high performance, reliable and environmentally friendly electricrnpropulsion solutions (EPUís).rnIn 2017, the company designed and built its first aerospace prototype motor, the magni5. By leveragingrnand further developing its technology features, magniX has flight?proven the successor to the magni5, arn560kW propulsion system known as the magni500.rnThe magni500 was designed, built, and tested to be aerospac
