The e-Genius is a manned electric airplane, which was developed by the Institute of Aircraft Design at the University of Stuttgart〔http://berblinger.ulm.de/uploads/Program_e.pdf?symfony=6604d0c324c091a7ee50dcf595fe78db〕 and first flew in May 2011. == Development == The e-Genius follows a line of airplanes with alternative propulsion systems, which have been developed at the Institute of Aircraft Design under leadership of Professor Rudolf Voit-Nitschmann: the solar-motor glider Icaré II (1996) and the predecessor of the e-Genius, the motor glider with a fuel cell propulsion system – Hydrogenius (2006). Both have been awarded with the Berblinger-Prize of the City of Ulm, Germany. Most of the airplane was built by a team of students between October 2010 and May 2011 in the workshop of the Institute of Aircraft Design of the University of Stuttgart.〔(Production Diary (German) )〕 The power capabilities of a modern electric propulsion system based on batteries are to be demonstrated with the e-Genius. In addition, Eric Scott Raymond and his team participated in the Green Flight Challenge of the Comparative Aircraft Flight Efficiency (CAFE) in the summer of 2011 in Santa Rosa, California with this aircraft, finishing second and winning the Lindbergh Prize for the quietest aircraft.〔(Second place for e-Genius )〕 The Green Flight Challenge is part of the Centennial Challenges, competition prize contests for non-government-funded technological achievements. The Green Flight Challenge has been endowed by NASA with prize money of $1,650,000.〔(Competitors of the ''GFC2011'' )〕 The goal of the competition was to find an aircraft which can fly a minimum range of about 200 miles at a minimum speed of 100 mph while using less than 200mpg and seat. On 25 May 2011, e-Genius successfully completed the first flight on the airfield in Mindelheim-Mattsies, Germany.〔(Press release from 30 May 2011 of the University of Stuttgart on the first flight ) PDF〕 On 15 June e-Genius made a flight over 340 km (211 miles) and an average speed of more than 160 km/h (100 mph), which was claimed to be the longest distance ever flown with an electric aircraft by that time.〔(Flightpath on Kasaero.de )〕 Nearly 2 years after these flights, another world record was claimed with a flight over 400 km (249 miles) during a measurement campaign in the context of the 2013 Idaflieg summer meeting. Apart from some maintenance work and some alterations to some subsystems, the e-Genius had remained technically unchanged since the Green Flight Challenge in 2011.〔(Idaflieg homepage (German) )〕 In September 2013, e-Genius won the Green Speed Cup with pilot Klaus Ohlmann.〔(Green Speed Cup )〕 On the way from its home base to the Green Speed Cup the e-Genius covered a distance of 560 km (348 mi) in two legs. , the developers are testing a range extender to 2.5 hours or about 400 km (250 mi).〔 (Wankel engine )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「E-Genius」の詳細全文を読む スポンサード リンク
