Le Bourget: Electric Hybrid Drives for Aircraft

27.06.2013
In cooperation with several partners, Siemens has created its second aircraft powered by an electric series hybrid drive system.

The two-seat DA36 E-Star 2 plane recently made its one-hour maiden flight and was then presented to aeronautics experts at the Paris Air Show. The electric series hybrid drive ensures quiet and energy-efficient operation.


The airplane is powered by a hybrid system comprising an integrated drive system from Siemens and a generator fed by a small rotary engine.

The DA36 E-Star 2's Integrated Drive System is characterized by its compactness and low weight. Its specific continuous output is 5 kW/kg.

After a predecessor model had demonstrated in 2011 that electric series hybrid drives are, in principle, suited for aircraft, the plane's second generation proves that the technology is also appropriate for commercial use.

Siemens, EADS, and Diamond Aircraft have been working for some years on this drive technology, which can reduce fuel consumption and emissions by around one fourth. The propeller is powered by an electric motor with 65 kilowatts of continuous output. The electricity is supplied through a generator by a small Wankel engine that consumes little fuel, because it runs evenly at a low output.

An EADS battery provides the plane with the energy it needs for take-off. The battery is recharged when the plane is cruising. Converters from Siemens supply the electric motor with power from the battery and the generator. The airplane takes off electrically - in other words, quietly and fuel-efficiently - and it has a sufficiently long range.

To power the plane, Siemens developed a new integrated drive system in which all of the components are optimally coordinated with one another. The hybrid drive is around 100 kilograms (kg) lighter than that of the predecessor model of 2011. The new aircraft's motor generates around five times as much output per kilogram as conventional drive systems. Siemens' global research organization Corporate Technology (CT) develops electric aircraft motors with very high power densities. In the future, these motors will also feature high-temperature superconductivity. CT was also responsible for the new plane's system integration and developed the control unit, which implements the pilot's commands for the batteries and the drivetrain.

The plane's passenger capacity and range make it a realistic option for commercial use. In addition, the drive system has a scalable output and can be expanded to power planes for 50 to 100 passengers. Today airlines spend one third of their operating costs on fuel. According to the Intergovernmental Panel on Climate Change (IPCC), aviation currently accounts for two percent of global carbon dioxide emissions. Siemens and EADS have now formed a long-term research partnership with Diamond Aircraft. The partners aim to introduce hybrid drive systems into helicopters, small planes, and commercial passenger aircraft. The system should achieve type certification in the general aviation category in three to five years.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
