Weight loss on electric airplanes

Special guide plane and tail-mounted engine: According to a French development company, it is not enough to replace the resources for the widespread use of electric aircraft, but also to change the usual design. According to the Conseil et Technique, a design similar to wing-mounted turboprop or jet engines is simply a bad concept for electric machines, instead proposing its own concept called Integrated Propeller Plane (IP2). According to an article in Ainonline, the most spectacular change would affect the tail. Around the rear of the fuselage of the Airbus A320 aircraft, there would be two rows of blades rotating opposite each other in a cover.

These would provide thrust with the help of an electric motor and build a two-part V-shaped guide plane above them. In addition, the electric propulsion is expected to be lighter than conventional propulsion, with other additional modifications that could make a medium passenger carrier much smaller than the current one. Industry experts immediately raised the question of how much the aircraft could fly with the available battery technologies and their low energy storage capacity by weight, and how much payload it could take on board.

According to the dreamers, if they could reduce the empty weight of a standard A320 by 30 tons, they could be packed with a battery with a capacity of 78 minutes of continuous operation at a capacity of 0.15 kWh / kilogram. And this can be upgraded to 323 minutes of flight time in up to five years if the average capacity increases to 0.4 kWh / kilogram. In addition, following the company’s “plug and fly” philosophy, drones, like drones, would be equipped with removable battery packs that could be conveniently replaced by ground staff during turnaround times between two flights, so there would be no need to wait for charging time. This requires some extra infrastructure to replace refueling systems, but can be attractive to discount airlines planning their flights in close succession. Conseil et Technique was recently involved in the development of the Airbus eVTOL vehicle, the City Airbus technology demonstrator. Now you want to get aircraft manufacturers to continue developing electric passenger carriers by licensing their concept and intellectual property or in partnership with the company. In addition, they hope that by transforming traditional types, the new solution can spread even sooner.
