The battery-powered electrical research aircraft e-Genius from the Institute for Aircraft Construction (IFB) at the University of Stuttgart was transported by air from the Kornwestheim/Pattonville airfield on the 560 km route to Straußberg at the beginning of September as a warm up for the Green Speed Cup competition.

The e-Genius even set an initial world record on the first transit stop to recharge in Dessau: before this no battery-powered aircraft had ever achieved the feat of travelling a distance of 393 km. On the very first competition day of the Green Speed Cup, the e-Genius had to up its game once more with a daily task of 405 km.
Yet the IFB pilots also successfully mastered this range and set the range record for battery-powered aircraft for a second time on 6th September 2013.
In the course of the competition, the conventionally motorised competitors stood no chance against the Stuttgart energy-saving miracle: with the same cruising speed the E-aircraft consumes only a fifth of the energy compared to conventional two-seaters. The e-Genius is still only a two-seater prototype, yet IFB professor Rudolf Voit-Nitschmann is hopeful that the research results in future can also be used for larger aircraft:
“We are able to show with the e-Genius that the electrical drive in the aircraft works reliably, with minimum noise and with excellent energy efficiency. This will be significant for future aircraft, e.g. in feeder traffic that is mainly serviced by turboprop aircraft.“
The electric aircraft e-Genius was designed and constructed under the leadership of Prof. Rudolf Voit-Nitschmann at the Institute for Aircraft Construction. The successful maiden flight was completed in May 2001. At present the e-Genius is the most efficient battery-powered aircraft worldwide, has a wingspan of 16.85 m, a take-off performance of 65 kW and approx. 900 kg take-off mass. The rechargeable power packs are able to store 56 kWh electrical energy, thereby contributing 300 kg to the take-off mass. The pilots completed the record distance with an average speed of 160 km/h and thereby required an energy equivalent of converted 1 litre for 100 km/h.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
