Siemens Motors Helps Aircraft Make First Flight into Aviation Electrification Milestones

[China Instrument Network Instrument Development] Siemens R&D personnel developed a new type of motor that weighs only 50 kilograms and can provide approximately 260 kilowatts of continuous output power, which is about five times that of other comparable drive systems. The Extra 330LE aerobatic aircraft with this world record-breaking propulsion system successfully completed its first flight on July 4th at the Schwarze Heide Airport near Dinslaken, Germany. The propulsion system powered the aircraft in an almost noise-free manner, having previously passed the first flight verification on June 24, 2016. This progress means that a hybrid aircraft carrying four or more seats is about to fly into the blue sky.

“This day will change the history of aviation.” Frank Anton, head of Siemens Academia Sinica’s electric aircraft program, said: “This is the first flight of a 250-kilowatt electric aircraft.” The Extra 330LE weighs close to 1,000 kilograms and is a flight test for a new propulsion system. model. As a stunt aircraft, Extra 330LE is particularly suitable for the limit testing of the relevant components, to provide a basis for improving its design.

In addition, the technology will also be included in the cooperation project between Siemens and Airbus launched in April 2016 to promote the development of electric aircraft. The electric drive unit can be flexibly expanded. Siemens and Airbus have jointly developed a regional passenger aircraft using a hybrid propulsion system based on this record-breaking motor. Anton said: "By 2030, we are expected to see electric planes with up to 100 passengers and a range of about 1,000 kilometers flying to the sky."

"The success of this first flight of the plane equipped with Siemens Propulsion System was a milestone on the road to electrification," said Siegfried Russwurm, chief technology officer of Siemens AG. “In order to succeed in the electrification of the aviation system, we need disruptive ideas and courage to take risks. This is why Siemens has developed the aircraft's electric propulsion system as the first project of its newly established independent company, 'next47', which is an independent start-up company.” Siemens hopes to use the hybrid aircraft propulsion system as one of the company's future businesses.

The German Aeronautic Research Program (LuFo) has provided support for the development of this motor. The Extra 330LE aerobatic aircraft was developed by companies such as Siemens, Extra Aircraft, MT-Propeller and Pipistrel (batteries).
