The Slar Impulse 2 aircraft began the final stage

The SOLAR Impulse 2 plane with solar panels, on Sunday, flew out of Cairo in the direction of Abu Dhabi, starting the last stage of his round-the-world trip, according to the officialwebsite of the project. The aircraft at this stage is piloted by the Swiss air-watering experimenter Bertrand Picar. It is expected that 48 hours will be required for the flight.

This route is a finish line in the circle of rounding, which began on March 9, 2015, Interfax notes. Participants in the experiment had to pause for several months due to the repair of the aircraft due to damage received during the flight from Japan to the Hawaiian Islands.

The Solar Impulse 2 aircraft is an enlarged version of the airplane, which crossed the United States from the coast to the coast in 2014 and put several records, including the most long -controlled man of solar energy - 26 hours.

Solar Impulse 2, like his predecessor, is piloted by the Swiss Bertrand Picar and Andre Borshberg. The plane is built of hydrocarbon fiber and has huge wings, their scope is 72 meters. At the same time, Solar Impulse 2 weighs only 2.3 tons. The upper side of the wings is covered with solar elements in the amount of about 17 thousand, which drive four electric motors.

The aircraft develops speed up to 140 km/h. The circulation project is designed to demonstrate the possibilities of using solar energy for experimental purposes.
