SolarStratos makes its first test flight

Last July, Solar Impulse 2, the world's first solar-powered aircraft, triumphantly completed its first round-the-world flight in Abu Dhabi last July. And on May 5 at 8:00 am over the Swiss town of Peierne, his successor SolarStratos two-seater aircraft, piloted by Damian Hishier, made its first seven-minute test flight at an altitude of 300 meters.

According to the plan of the creators of SolarStratos in 2018, it should rise to the borders of space at a height of 25, 000 meters, using the energy of solar panels. During the first mission, this will take him 2 hours, and the very stay in space will last only 15 minutes, followed by a three-hour descent to Earth.

The aircraft crew will be able to observe the curvature of the Earth and the stars during the daytime. At this time, a truly Antarctic cold of -70 ° C and a pressure of only 5% of the earth's pressure will stand overboard. Under such conditions, it is impossible to use a parachute.

SolarStrator 8, 7 meters long, wingspan 25 meters. It is powered by a 32-kilowatt electric motor and a 20-kilowatt Li-Io battery that is charged by 72 square meters of solar panels. meters. SolarStratos is capable of staying in the sky for 24 hours. The result of the first flight was summed up by its creator Rafael Domian:

"We were looking forward to this moment and are glad that the flight was completed successfully."
