世界上首架可实现昼夜飞行的太阳能飞机——“阳光动力”号本周三在瑞士首都伯尔尼附近的一座军用机场成功完成首次试飞。此次试飞持续了87分钟，最高飞行高度达到了1200米。试飞的飞行员表示，试飞过程中飞机性能与在飞行模拟器上得到的结果一致，其控制性完全符合预期。据介绍，“阳光动力”号飞机翼展与空客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，飞机机翼上铺排了将近12000块太阳能板，为4部螺旋桨引擎提供动力，并将多余电量存储到电池内以供夜航使用。这架太阳能飞机最终预期的平均飞行速度将为每小时70千米，而最高飞行高度也有望达到8500米，计划将在2012年进行环球飞行。[文章版权 禁止转载:考试与评价 Cdi[Uk8Z2i=
