This Is An Innovative Electrical Motor For Aircraft Developed Past Times Siemens Researchers

Siemens is a pioneer inwards electrical too hybrid electrical aircraft engine technology. As per press loose published past times Siemens, an electrical aircraft engine 5 times to a greater extent than powerful than existing electrical aircraft motors has been developed past times High German engineering scientific discipline giant Siemens, paving the agency for commercial-scale electricity-powered air transportation. 

Siemens researchers cause got developed a novel type of electrical motor that, amongst a weight of only fifty kilograms, delivers a continuous output of nigh 260 kilowatts – 5 times to a greater extent than than comparable displace systems. The motor has been especially designed for purpose inwards aircraft. Thanks to its record-setting power-to-weight ratio, larger aircraft amongst takeoff weights of upward to 2 tons volition at nowadays endure able to purpose electrical drives for the kickoff time.

Since the novel motor delivers its record-setting performance at rotational speeds of only 2,500 revolutions per minute, it tin displace propellers directly, without the purpose of a transmission. "This project design volition become inwards possible to build serial hybrid-electric aircraft amongst iv or to a greater extent than seats," said Frank Anton, Head of eAircraft at Siemens Corporate Technology, the company's fundamental query unit.

To implement the world-record motor, Siemens' experts scrutinized all the components of previous motors too optimized them upward to their technical limits. New simulation techniques too sophisticated lightweight structure enabled the displace organisation to hit a unique weight-to-performance ratio of 5 kilowatts (kW) per kilogram (kg).

The electrical motors of comparable forcefulness that are used inwards industrial applications deliver less than ane kW per kg. The performance of the displace systems used inwards electrical vehicles is nigh 2 kW per kg. Since the novel motor delivers its record-setting performance at rotational speeds of only 2,500 revolutions per minute, it tin displace propellers directly, without the purpose of a transmission.

"This project design volition become inwards possible to build serial hybrid-electric aircraft amongst iv or to a greater extent than seats," said Frank Anton, Head of eAircraft at Siemens Corporate Technology, the company's fundamental query unit. The motor is scheduled to get flight-testing earlier the cease of 2015. In the side past times side step, the Siemens researchers volition boost output further. "We're convinced that the purpose of hybrid-electric drives inwards regional airliners amongst fifty to 100 passengers is a existent medium-term possibility," said Anton.

The evolution of this motor was supported past times the High German Aviation Research Program LuFo inwards a projection of Grob Aircraft too Siemens. In 2013, Siemens, Airbus too Diamond Aircraft successfully flight-tested a serial hybrid-electric displace inwards a DA36 E-Star 2 motor glider for the kickoff time. The exam aircraft had a ability output of lx kW.

In 2013, the theatre successfully tested a serial of hybrid-electric motors inwards cooperation amongst Airbus too Diamond Aircraft. The motor, providing 60kW, was used to ability the DA36 E-Star 2 glider, which was kickoff introduced at the Paris Airshow inwards 2013.
