Solar plane begins to travel around the world




Solar plane begins to travel around the world The first attempt started early Monday morning to fly around the world with an aircraft powered by solar energy in Abu Dhabi. The plane took to the air at 07:12 local time to promote green energy.

The solar airplane Solar Impulse 2 has a wingspan of 72 feet, 8 feet shorter than the wingspan of an Airbus A380. 2300 kilograms of the Si2 is more than 150 times lighter than an empty A380. The 17 248 solar cells on top of the wings with a total area of ​​269.5 square meters, provide energy to four lithium-ion batteries and four electric motors of 13kW each, or 17,4PK. The propellers with a diameter of 4 meters lift aircraft already at 35 kilometers per hour from the ground up to a maximum speed of 140 kilometers per hour and the unit with an average speed of 90km / h flying. At night, the average speed is lower, to 60km / h, to save energy.

The Si2 is only room for one pilot, causing several stops are planned to switch between the pilots Bertrand Piccard and André Borschberg. The longest distances across the Pacific and Atlantic Oceans will last between around five and six days, with the longest distance about 8500 kilometers will amount to.

The flight will be monitored from the principality of Monaco, where 65 men are stationed, including air traffic controllers, meteorologists and technicians. A team of ground staff with the same size traveling by plane just join the pilots .
