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: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
