Solar aircraft Solar Impulse completes second trip around the world




Solar Impulse 2 is Monday night at 2:05 pm landed in Abu Dhabi where the solar airplane began his journey to the world on March 9, 2015. The seventeenth and final leg of the flight around the world began 48 hours and 37 minutes earlier in Cairo.

The last part of the 40,000-kilometer journey flew Bertrand Piccard. Piccard began thirteen years ago with the project together with the Swiss engineer Andre Borschberg. Upon landing said Piccard: “The future is clean, the future you, the future is now, let’s take a step further.”

The last stage of Cairo walked across the Red Sea from Saudi Arabia, Bahrain and Qatar to land in Abu Dhabi, capital of the United Arab Emirates. The flight followed the stage of 3745 kilometers from Seville in Spain and Cairo, where the device had needed 48 hours and 50 minutes, just thirteen minutes longer than the time it sat the distance of 2794 kilometers of the last stage.

The aircraft has a wingspan of 68 meters, which is equivalent to that of a Boeing 747. The solar aircraft weighs 2,300 kilograms instead of 300 tons of 747. At the top plane is covered with 17,000 solar cells the four meter long propellers drive powered by four electric motors.

Solar Impulse 2 is prone to bad weather, causing flight over the Pacific Ocean nearly a year had to be postponed because by damage to the battery could not be flown further in time from Nagoya in Japan to Hawaii. It was therefore directly the longest distance of 8924 kilometers. The pilot at that distance was Borschberg who did it 118 hours. The longest flight was initially Nanjing in China go to Hawaii, but the plane had to land when in Nagoya. The distance from Nanjing to Hawaii was 9132 kilometers and would have had to take about 144 hours.

Piccard completed the second longest distance to travel across the Atlantic from New York to Seville from 6265 kilometers in 71 hours and 8 minutes.

The team will now continue to pursue the promotion of clean technologies in aviation, but also solar-powered clean unmanned aircraft fly much higher so that no disturbing influences of bad weather or normal aircraft. This kind of autonomous unmanned aircraft could in many cases replace the need for satellites.
