E-Genius
The e- Genius is a man-carrying electric aircraft, which was developed by the Institute of Aircraft Design at the University of Stuttgart. The first flight took place on 25 May 2011.
Development
The e -Genius is a two-seat touring motor glider with electric drive. Designed and built the aircraft was at the Institute of Aircraft Design at the University of Stuttgart ( IFB) under the direction of Professor Voit Nitsch man. The aircraft is based on the Hydrogenius, a theoretical design of a fuel cell aircraft which won the 2006 Berblinger Prize of the city of Ulm. With the e -Genius (winner of the 1996 Berblinger price also ) was born on IFB designed and built the second practical aircraft with an alternative drive concept after Icaré II.
The majority of the aircraft was built in just eight months between October 2010 and May 2011 in the workshop of the IFB. On 25 May 2011 the first flight took place on the factory airfield of the Grob Aircraft in Mindelheim - Mattsies. Just 3 weeks after the first flight of the e -Genius has already demonstrated its capabilities by the task of the Green Flight Challenge could already be flown as part of the flight test. The aircraft is used for research and testing of the electric flight and is stationed at the airfield Pattonville EDTQ.
In autumn 2011 the aircraft in California participated in the Green Flight Challenge the Comparative Aircraft Flight Efficiency ( CAFE). Wanted was in this competition an aircraft that can cover a distance of at least 320 km with a speed of at least 160 km / h and fly to less than 1,176 gallons of gasoline equivalent per 100 kilometers may consume (one gallon to 200 miles ) and passenger. In this competition the e -Genius won the Lindbergh Prize for the quietest aircraft and achieved overall in the Green Flight Challenge second place.
Currently, the e -Genius is the world's most powerful electric aircraft to be operated continuously. On August 14, 2013 e -Genius flew as part of a test flight at a stretch 400 km in four rounds to each 100 km with an average speed of 140-175 km / h per round.
In September 2013, the e -Genius took part in the Green Speed Cup. Here, the e -Genius put the 560 km of Pattonville to Strausberg back in just under 4 hours of flight time. A stopover was in Dessau. Competition, each with a rating flight over 282 km and 405 km could win the Stuttgart aircraft with enormous distance ahead of the competition.
Technology
The e -Genius is a two-seat high-wing monoplane in CFRP composite design with retractable landing gear. The seating arrangement in the cockpit is side- by-side, that side by side. It is driven by a water-cooled, permanent magnet synchronous motor, which drives an electrically adjustable tractor propeller with 2.2 m diameter. The 27 -pound engine of the Slovenian manufacturer Sineton is currently operating with a continuous output of 40 kWe and a starting capacity of 72 kWe. The drive unit is attached to the upper end of the vertical tail fin of the conventional cross- tail. In focus close behind the pilot seats, the four packages of lithium -ion battery are installed with a total storage capacity of 56 kWh. In cruise flight e -Genius is usually with a capacity of 10 - 20 kWe operated.
