An electric aircraft motor unveiled by Siemens in 2015 is a true powerhouse. Weighing only 50 kilograms, it generates 260 kilowatts of power, resulting in an unprecedented power-to-weight ratio. And that’s not the only reason it will make aviation history. Siemens experts also installed the motor and its entire power train into a two-seater aircraft, the Extra 330LE.
“This first flight is a milestone in the history of electric aviation drives,” says Frank Anton from Corporate Technology (CT), Siemens’ central research and development department. Anton and his team got the first electric airplane with an output of one fourth of a megawatt airborne, and they did so in accordance with the flight conditions of the European Aviation Safety Agency and a permit-to-flight from Germany’s Federal Aviation Office.
