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.
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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
