Began testing stratospheric elektrosamoleta SolarStratos
Swiss SolarStratos developers have begun to test the solar aircraft designed to fly in the stratosphere. The first flight took place at an altitude of 300 meters and lasted about seven minutes.
On the wings of the aircraft has solar batteries that generate power for motor 32 kW and simultaneously charge the lithium-ion battery 20 kW. SolarStratos wingspan of approximately 25 meters, the length - 8, 5 meters and weighs little more than 450 kg.
To facilitate the design of the aircraft cabin is not insulated and sealed, so pilots will fly on it in special suits that can withstand temperatures down to minus 56 degrees. The ascent to an altitude of 24,000 meters at the aircraft will take about two hours. According to the developers, a fully flying aircraft could already in 2019, but until then he will undergo more tests and a number of design improvements.
Despite the fact that the launch SolarStratos will cost 10 million dollars, the developers are confident that these planes will be needed in the future - to the edge of space flights will allow to carry out research and to entertain the tourists.
