Bertrand Piccard and André Borschberg of Solar Impulse have already proven their one-seat airplane can travel day and night using no fuel. But now the pair is getting ready to show the world that is possible to travel around the world using only solar power in their next-generation prototype.
Their first prototype, HB-SIA, has a wingspan that is equal to that of an Airbus A340, but despite its size, it weighs only as much as an average car.
In 2010, the two flew the prototype—powered by 12,000 photovoltaic cells that cover its wings to absorb solar energy and transfer it to the aircraft’s four batteries—for 26 hours, proving that a solar-powered plane could also fly at night.
This July, however, the two proved that a solar airplane could fly from Europe to Africa and back using only solar power. The nearly 4,000-mile flight, completed two months after they took off, was finished in eight legs and covered four countries and two continents. The goal of this mission was to further prove the plane’s reliability, while providing a rehearsal for its round-the-world flight planned for 2015 in an updated version of the plane called the HB-SIB.
The around-the-world flight was originally scheduled for 2014, but in July, HB-SIB’s wing spar cracked and the final structural test failed.
“It’s the first time a final structural test has failed in the history of the project and even though it’s hard to accept it’s an extremely valuable learning experience,” the Solar Impulse website states. “Moreover, it has made room for some stimulating brainstorming sessions within the team not only on how to use the time gained to improve the reliability of the aircraft but also to further emphasize the project’s message and value.”
Aircraft Power and Fuel,
Mexico has lifted a requirement that pilots of arriving and departing private general aviation flights use a third party provider to file advance passenger information system (APIS) manifests.
Leaders of the International Council of Aircraft Owner and Pilot Associations’ (IAOPA) 73 worldwide affiliates convened in Beijing in September for their twenty-seventh biennial World Assembly to discuss challenges confronting the world’s general aviation community.
A strong cold front sweeping through England recently ignited strong showers and storms. One of the storms passing through the Midlands spawned a menacing funnel cloud or possible tornado near East Midlands airport, which was photographed just as a Ryanair jet was taking off. However, it’s not clear if the vortex photographed is an actual tornado, because there is no view of the ground. In order for a funnel cloud to be classified as a tornado, it must make ground contact. Credit: Alamy News Team, from ITV News
