Electric aircraft propulsion offers quiet operation but big challenges

Electrification is having profound impacts on the automotive industry. Electric aircraft may have a similar impact on the aerospace sector. Attracted by the low weight and cost of electric motors compared with gas turbine jet engines, and particularly by their near-silent operation and potential for zero emissions, the civil aviation sector is showing increasing interest in using electricity to power future flight, at least over the relatively short distances that dominate city-to-city aviation. While jets are unassailable as the prime movers for intercontinental long-haul airliners — nobody’s suggesting that electric aircraft could transport passengers from Europe to Asia, across […]
