　　Solar Impulse program will flight around the world by solar-powered.

　　Solar Impulse is established in Switzerland in 2010. HB-SIA prototype has become a unique history, and the first to achieve a flying day and night without fuel 26 hours of aircraft, setting a new historic record, to show the world the prior art in energy efficiency and renewable energy production potential.??? According to data show HB-SIA prototype with the wingspan of an Airbus A340 rather, the weight is only 1.5 tones prototype wing and horizontal tail covered with solar panels, and is equipped with 400 kg of PCT batteries and four electric motors driving propellers. For like the HB-SIA such a large, light, and slow flight speed of the aircraft, flight control is the biggest challenge, especially when turbulence is encountered. To reduce energy consumption and reduce the number of configurations, including spaces. The second prototype HB-SIB project is toward its 2014 goal of world flight without fuel accelerated forward.
