Battery-powered aircraft e-Genius on cloud nine

25.09.2013
World record and victory at Green Speed Cup

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.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
