A solar-powered airplane designed to fly day and night without fuel or emissions successfully made its first test flight above the Swiss countryside on Wednesday.

　　世界上首架无需燃料可实现昼夜飞行的太阳能飞机——“阳光动力”号本周三在瑞士成功完成试飞。

　　The Solar Impulse, which has 12,000 solar cells built into its wings, is a prototype for an aircraft intended to fly around the world without fuel in 2012.

　　阳光动力”号飞机翼铺排了将近12000块太阳能板。正式的“太阳驱动”号预计2012年有望执行无燃料环球飞行任务。

　　It glided for 87 minutes above western Switzerland at an altitude of 1,200 meters (3,937 feet) with German test pilot Markus Scherdel at the controls.

　　由德国籍试飞员马库斯·舍德尔驾驶的“阳光动力”在瑞士西部高空滑翔了87分钟，飞行高度达到了1200米。

　　"Everything went as it should," Scherdel said after landing.

　　“一切按预料进行。”舍德尔帕返回地面后表示。

　　It took six years to build the carbon fiber aircraft, which has the wingspan of an Airbus A340 and weighs as much as a mid-size car (1,600 kg).

　　该架碳化纤维材料的“阳光动力”样机经大约6年制成，翼展与空客340的翼展长度相当，机身重量约1600千克，相当于一辆普通中型轿车的重量。

　　The prototype made a "flea hop" in December 2009, flying a distance of 350 meters one meter above the runway of a military airbase near Zurich.

　　去年12月“阳光动力”样机曾在瑞士城市苏黎世附近一座空军基地进行了首飞，飞行高度大约1米，飞行距离约为350米。此次飞行后被称做“跳蚤跳”。
