Walter Extra, in addition to his feats of designing the famous line of Extra aerobatic aircraft and performing as a concert pianist, now has a time-to-climb record from Fédération Aéronautique Internationale (FAI) in an electrically powered Extra 330LE.
In the air and without engine noise the experience is “almost silent,” Extra said in a press release.
“This day will change aviation,” Frank Anton, head of eAircraft at Siemens, said at the time of the first flight. “This is the first time that an electric aircraft in the quarter-megawatt performance class has flown.” The aircraft climbed at an average of more than 2,200 feet per minute.
Siemens developed a new type of electric motor that weighs only 110 pounds but delivers a continuous output of 260 kilowatts (348 horsepower) to power the Extra aerobatic airplane. That is five times more than previous comparable systems, the company claimed in a press release.
The companies claimed that an electric-powered future for some aircraft is now possible, a claim heard many times in the past. A press release issued by the companies said a 100-passenger short-haul aircraft on 600-mile routes is now possible “by 2030.”
Siemens said the company joined with Extra Flugzeugbau because aerobatic airplanes are “particularly well suited” to taking components to their limit, “testing them and enhancing their design.”
