Switzerland, “the Sun
” Solar-driven ” Number Solar Net HC Swiss designed solar-powered aircraft, “the Sun-driven” prototype No. 7, the successful test flight. This aircraft as large as the Airbus aircraft, heavy aircraft such as the car to help a bike with a considerable speed, to fly around the world an important step.
Quiet and smooth Around 10:30 local time, German test pilot Marcus? Schadel driving “the sun-driven” No. prototype air base in western Switzerland payerne taxiing to take off after a few hundred meters, about 45 kilometers per hour.
With 4 sets of 10-horsepower electric motor drive power, the aircraft gradually climb to an altitude of 1200 meters, completed a series of shift, swing and tilt movements. About 87 minutes after the flight, the aircraft hovered over the runway a few minutes, the R & D team members cheering slowly landing.
“Solar driven” project leader, Swiss adventurer Bertrand? Picard described the flight test process “quiet, calm.” Schadel described the aircraft taking off and landing “aircraft as common as” safe.
“All press is expected to be. Flight was very successful. We complete the test, then return to earth safely.” Schadel said.
“Solar driven” No. prototype made by about 6 years, last December in the Swiss city of Zurich, an airbase near the flight altitude of about 1 meter, flying less than 400 meters. Reuters said the first flight as a “jumping flea.”
Aim at global “Solar driven” No. prototype made from carbon fiber materials, with a seat mounted on the wing to rely on some 12,000 pairs of solar panels to provide power. The wings are long and slender wing span 63.4 m, and the Airbus A340 aircraft quite. Aircraft weight 1.6 tons, the equivalent of a midsize sedan.
“Sun-driven” project participants about 70 people, is expected to cost more than 93 million U.S. dollars. 7 test flight is successful, developers intend to conduct more test flights, including scheduled for this summer in payerne 36 hours a night flight, to collect relevant data, improved aircraft design, to ultimately create a formal “Solar-driven” No. preparation.
Official “Solar-driven” was expected to take off in 2012 or 2013, is expected to implement global mission.
Picard said: “Our goal is to not waste fuel in flight under day and night, to show the renewable Energy The importance that we can use renewable energy to achieve the impossible. ”
In accordance with the developers envisioned, “the Sun-driven” was the ultimate flying 70 kilometers per hour, the maximum flying height of 8500 meters above sea level.
