We did the Alps!

First Crossing of the Alps in a Battery Powered Aircraft

e-Genius showed the practicability of battery powered aircraft with a spectacular flight over the Alps. A milestone towards an energy efficient and carbon-neutral aviation has been reached.

Saturday morning, the electric aircraft “e-Genius” flew from the airfield Hahnweide near Stuttgart over the Alps to Italy. On its way to the north-Italian airfield Calcinate del Pesce, the hi-tech aircraft had to cover a distance of 320 km and climbed to an altitude of 4000 m in order to pass the Swiss summits safely (click here for details).

e-Genius was flown by the experienced record pilot Klaus Ohlmann and Ingmar Geiß of the University of Stuttgart. The aircraft arrived at its destination airfield in little over two hours. On the same day, the batteries were recharged and e-Genius headed back to Stuttgart in the afternoon. This was a particular challenge because of the steep profile of the Swiss Alps. In order to have enough time to climb, a flight path through the Gotthardpass was chosen, which meant the aircraft had to cover an even longer 365 km distance back to Germany (details).

Besides the lack of carbon and noise emission, the energy consumption of the flight showed the huge potential of the new aircraft technology: for both flights combined, only 83 kWh were needed, the energy contained in 9.2 l of fuel. This leads to a total energy expense of only 21€ for the whole trip, assuming current electricity prices in Germany.

The electric aircraft e-Genius was developed at the University of Stuttgart and is in a flight test program since May 2011. The goal of the project is the investigation of new propulsion technologies and aircraft configuration in order to minimize energy consumption as well as the carbon and noise emission of future aircraft.

This historic flight was only possible with the support of the Aviation Association of Baden-Wuerttemberg as well as the glider clubs Wolf Hirth and Aero Club Stuttgart.

Just an ordinary test flight – but a fast one

The German weather in November isn’t famous for its perfect VFR conditions but this year there are some quite good days. So we used one day with a nice inversion to test the e-Genius motor at higher power in horizontal flight and flew a 100 km rectangle – and we needed less than 30 minutes. We achieved 213 km/h average speed with our battery powered airplane. It was only a test flight therefore it isn’t an official record but we are very proud to share this flight.

If you would like to have a closer look to this flight you can open the *.kmz file in google earth!

Records, Records, Records!

Experienced hands plus a high-performance airplane plus one week equals seven world records.

Admittedly, this equation is not quite mathematic but in case of Klaus Ohlmann and the e-Genius, it is true. The airplane spent the third week of July in Seeres – La Bâtie, France where Klaus Ohlmann achieved stunning seven FAI ( Fédération Aéronautique International) World records in the Category of Electric Airplanes.
In three flights (July 15th, 18th and 19th) he attained:
- Speed on a 100 km round trip : 178.1 km/h (96kt)
- Speed on a 500 km round trip : 93.03 km/h (50kt)
- Distance of 504 km (312mi)
- Absolute altitude of 6,376 m MSL (20918ft)
- Time to climb to 6,000 m (20,000ft) : 1:53 min
- Altitude maintained for at least 90s : 6350m (20833ft)
- Speed over 15 km on a straight line: 229.7 km/h (124kt)

While using only 25kWh for 180 km, Klaus managed to shoot some impressive footage, which we are excited to share with you.

e-Genius in Serres, France

Klaus Ohlmann is evaluating the gliding performance of e-Genius

World record pilot Klaus Ohlmann, who piloted the e-Genius at the NASA Green Flight Challenge and the Green Speed Cup, is evaluating the gliding performance of e-Genius in the alps. After the record flights last August where the aircraft demonstrated its motorized flight range of > 400 km, we are now looking into what is possible with the support of thermals, winds, etc. With the clean and efficient airframe we are expecting spectacular flights!
More news to come!

Flight Formation of e-Genius and icaré 2

Both manned aircrafts of the Institute of Aircraft Design (IFB) fly simultaneously and side by side for the first time!

The two aircrafts flew at the same speed in formation. It is awesome that flight formations of aircrafts with different wing loadings such as 15 kg/m² (icaré 2) and 65 kg/m² (e-Genius) are possible. While the airspeed indicator of icaré 2 was near red line, e-Genius flew at the necessary safety margin above stall speed.

Amazing e-Genius Week!

Great news! We won the Green Speed Cup in Strausberg and set new benchmarks for the range of battery-powered aircrafts!

On 5th of September, e-Genius flew from Pattonville to Strausberg (total distance 592 km) with a stop in Dessau (Link). The first leg with its 393 km is the longest cross-country flight with a battery-powered airplane.

At the first competition day of the Green Speed Cup, we then set yet another range record for e-Genius, covering a triangle of 404.9 km in 2 hours 40 minutes and landing with a 30-minutes reserve (Link). Weak thermals (~1 m/s) and a constant wind (25 km/h, head- and tailwind) underline the performance of the aircraft.

Finally, after three competition days, we won the Green Speed Cup! The distribution of the points (Link) shows the advantages of a sophisticated electric aircraft design. The competition is documented in a short clip (Link) which was broadcasted in German television.

e-Genius Back in Air & Heading for 2013 Flight Tests

After a long period of work e-Genius is ready for the new flight season

In the last months e-Genius was updated to improve reliability and maintenance items. Most of the work which was done is not very apperent like new wiring and cable protection. But we are very proud that e-Genius which is still a prototye research aircraft is now on a new level in terms of suitability for everyday use.

Test Flight Campaign Goes On

e-Genius Completed Flights Without Prop at the IDAFLIEG Summer Meeting 2012

After the towing by a motorized plane, the e-Genius glided to compare its gliding performance to the DG 300/17 of the DLR (German research centre for aeronautics and space).

This is the video of the flight test campaign without propeller to determine the lift - drag ratio of the e-Genius airframe. This campaign was realized during IDAFLIEG summer meeting near Aalen, 70 kilometres west of Stuttgart.

See the pictures below to get a nice impression of this flight test! Sincere thanks are given to IDAFLIEG for their support!

"Übermorgenmacher": Tribute to the e-Genius key team members

The state of Baden-Württemberg honours leading engineers of our team for their new concepts for innovative and ecological flying.

The distinction took place in the government department for science, research and arts on the 25 July 2012. The trophies have been handed over by Minister Theresia Bauer. In her honorific speech she expressed:
"The competition aircraft e-Genius is probably the most modern electric aircraft at present, unmatched by the competitors concerning speed, energy consumption and noise exposure. Today, we not only honour the idea, but rather the sensational performance of the team around Professor Voit-Nitschmann."

All in all, there have been 500 applicants for the prize. The jury honoured 60 persons, it is remarkable that five of them are from our team! Please click on this link to see the official "Übermorgenmacher" website (only in German).

Please find our category Highlights to get more information about our awardees.

Flight test campaign progress

e-Genius towed by a Pawnee

e-Genius was towed by a Piper Pawnee in Grabenstetten, Germany, as a first test for the gilder polar campaign. As you can see towing nearly 900 kg from a gras strip is a lot even for a Pawnee.

We would like to say THANK YOU to the FLG Grabenstetten for supporting our e-Genius test campaign.

Due to the "Wednesday-landing" on this video we found out that our landing gear dampers had to much pressure. With the help of LTB Kiener Flug in EDPA we have refilled them. On normal e-Genius landings the tail wheel always touches the ground first so we could improve the landing comfort with this action.
