32 Motors across a long Wing Cosmic Aerospace has announced a different kind of “blown wing,” hiding 32 specially developed electric turbines across the inner span of a high-aspect-ratio wing. Cosmic will attempt to achieve jet-like speeds at half the cost of fossil-fuel or sustainable aviation fuel (SAF) powered jet. Electric-flight.eu notes the American-Belgian firm was founded by “graduates of Boom Supersonic, NASA, Oxford and Kittyhawk,” a broad spectrum of talent. Part of that team is creating a fully-electric “jet engine,” currently under test at Limburg Regional Airport in Belgium. The motors will be fed by packs of 360-Watt-hour per kilogram batteries, achievable with today’s technology. This enables up to 1,000 kilometer (600 mile) range for a long-winged craft carrying 24 passengers. “Unlike other startups in the field, which are mostly focused on sustainable jet fuels, hydrogen, and battery tech, Cosmic has focused its engineering efforts on better propulsion systems and a unique air frame design, CEO Christopher Chahine told …
