We already know the exact details of the journey around the world of the first solar plane, the Solar Impulse 2. The whole trip will last five months, with the aircraft flying 25 days in the air, overcoming a distance of over 35,000 kilometers and doing 12 stops along the way.
A few months ago, Solar Impulse announced a worldwide expedition aboard Solar Impulse 2, which is powered solely by solar energy. The expedition aims to show the world that in the future planes can function solely on renewable energy sources and will be as functional as the machines currently used.
We just got to know the exact details of this event, which will be attended by Bertrand Piccard and André Borschberg, pilots and co-founders of Solar Impulse. The expedition will start at the end of February or early March, and the aircraft will depart from Abu Dhabi in the Persian Gulf and then will head to Oman, India and China. Then beat the Pacific, stopping in Hawaii to take a few stops in the United States, then go to Europe, North Africa and finish the expedition in the place where it started.
The expedition will last five months, with the Solar Impulse 2 spending 25 days in total, covering a distance of 35,000 kilometers and stopping at 12 places in the world. The plane will fly both during the day and at night, and then the energy will be collected by special batteries that accumulate during the day.
Solar Impulse 2 is an airplane with a wingspan of up to 72 meters, so it is significantly larger than the Boeing 747, however, its weight is only 2300 kg. It was obtained through the use of carbon fiber, as well as the special technology used in racing yachts, which makes the plating three times lighter than paper. The machine is powered by four electric motors, which deliver 17,248 photovoltaic panels of just 135 microns thick, embedded in the wing surface and protected with fluorine copolymer. The energy produced by them is then stored in polymer batteries of a total weight of 633 kg.
Thanks to this drive the machine has almost unlimited range and moves at an average speed of 50-100 km / h.
