Successfully test flight test machine equipped with high efficiency motor aiming to realize "hybrid airplane"

Instead of engines using fuel, flying in the sky with electric driven motorsElectric airplaneI combined the engine and the motorHybrid airplaneResearch and development aimed at realization of this technology is proceeding. Meanwhile, Siemens (Siemens), a German company, has successfully tested an aircraft equipped with an electric motor for aircraft with a dramatically higher efficiency than before.

On Monday, July 11, 2016, the test machine named "EA-300LE" which succeeded in the first flight by the electric motor. This aircraft is a German aircraft manufacturer "extra"The engine was dropped from the sports aircraft" EA - 300 "and replaced by Siemens' motor. By the way, with "Red Bull Air Race"Aircraft that a Japanese pilot Muroya player rides "300 L"He is a brother.


The mounted motor is small in size, as much as the size of the car's tire. A motor capable of obtaining 260 kilowatts of output from a body weighing 50 kg, the output power weight ratio (power weight ratio) per kilogram obtained by dividing the output by weight is about 5.2 kW / kg. Even though this is equivalent to about 5 times the conventional electric motor, you can see a glimpse of its high performance.


As for this motor, it has been posted in GIGAZINE in April 2015. Detailed performance is mentioned in the following article.

The state that the EA - 300LE actually flying is contained in the following movie.

EA-300LE is a two-seater sports aircraft. This time it is a pilot's boarding by saying a test flight, but if it sees closely it seems that some kind of equipment is loaded on the undercut.


Dr. Frank Anton, Siemens who leads the development said, "Although the world is being electrified, this is not limited to the sea and the land, it can be said to the sky."


EA-300LE which raises the output and fly to the sky. Since the mounted motor has an output that can also fly a 4-seater plane, it does not feel the power shortage at all for the aircraft based on a lightweight compact aircraft.

In the usual case the engine room with a big engine was loaded with a very small motor and a battery.


The flight seems to have been supplied with electricity from the battery, but what is most expected in the future is a hybrid type electric aircraft that uses both a power generation engine and a driving motor. It seems that future development will be promoted with the aim of commercializing a small passenger aircraft of about 100 people equipped with this mechanism around 2030.
