国产大飞机C919成功首飞后安全着陆(组图)
2017-05-05 14:23:28 中国青年网
我国首型拥有完全自主知识产权的大型客机C919于5日下午2点在上海浦东机场顺利升空,开始首次飞行测试。中国商飞公司试飞中心试飞工程部部长由立岩4日透露,首飞任务预计持续一个半至两小时,最大飞行高度1万英尺(3048米)、最大速度170节(约每小时315公里)。任务分为五个阶段共15个试验点,其中将在8500英尺高空模拟着陆。
国产大型客机C919在进行70多分钟的试飞后返回上海浦东机场,成功着陆!

飞行员会在1万英尺空中,把8500英尺高度作为假想跑道,模拟进近、着陆和复飞过程,三个动作要一气呵成,建立飞行员返场着陆的信心。此后飞机返回浦东机场降落,在最后一个试验点再次开展三向操作检查,确认飞机经过飞行后,舵面没有受气动载荷作用而出现大的偏差。

此次首飞将有飞机伴飞,这在我国民机试飞中尚属首次。伴飞飞机将提前进入首飞空域,沿首飞航线飞行一次,了解首飞高度层的风、温度、云况等气象情况,避免存在危险天气影响飞行。

C919起飞后,伴飞飞机将与它一起飞行并保持通讯,观察其舵面、起落架,以及是否漏油等,并提供高度、速度参考。此外在条件允许情况下,伴飞飞机乘员将对C919进行外部摄影摄像,保留首飞影像资料。
