国产飞机C919将择时首飞 团队解密:飞到天上干点啥?

2017-05-05 14:24:17   央广网

由立岩介绍,C919的首飞是我国国内第一次在首飞中有除了飞行员以外的人员登机。除了观察员之外,还有两名试飞工程师。他们登机是做什么呢?由立岩介绍:“试飞工程师在客舱。客舱专门有几组机柜,把整个机载测试系统的重要参数引介到机柜,它有电脑屏幕,可以实时显示飞机一些参数曲线、重要的技术参数标准。他们主要在客舱里通过这些参数的判读和飞行员协同。”

目前,C919首飞飞机的客舱中还没有座椅和行李架等设施,而是乘有用于试验的机柜。C919的首飞和平时航线的飞行不同,除了要安全起降、飞行,抵达目的地外,还需要在飞行过程中进行一系列的试验和测试。而飞行员在驾驶舱,试飞工程师在客舱,他们之间如何协作进行试验呢?

由立岩介绍:“比如我现在开始进行T1试验点,试飞工程师开始进行整个数据的记录和判读。飞行员做完以后,试飞工程师会告诉他你做的好不好,整个数据有没有效。说OK进行下个试验点。他们之间内部通过耳麦内话系统,有语音沟通。”

C919要在首飞中完成多少试验?据由立岩介绍,预计这一飞要飞1个半小时到2个小时左右,在这当中,要完成的事情可不少,首飞的飞行任务有15个试验点,“第一个试验点是在地面,完成三项操纵检查,它的输入、响应功能都是正常的。因为飞机在第一次离地升空,包括到飞行过程当中,主要就是靠这些活动面来控制飞行姿态,所以在飞行前这是必须要完成的一个动作。”

C919标准航程型设计航程为4075公里,相当于一口气能从长春飞到拉萨。不过首飞按计划将从上海浦东国际机场起飞,最后,还是回到这里。而在最终降落前,在高空中C919应该已经完成一次模拟着陆了,“首飞高度在一万英尺,它会假想一个8500英尺空的机场去完成整个进近、着陆动作,包括遇到特情以后复飞的动作。在整个工作完成以后就建立了飞行员对返场着陆的信心,对整个飞机的特性也有了全面的了解。这时候就退出空域,飞机就回到浦东机场。”

除了飞行数据外,机长的感受是设计团队最关注的试验结果之一。首飞前,对于飞机的状态,首飞机组机长蔡俊说,飞行员心里有数,“害怕到没有过。更多的想一些飞机现在状态到底适不适合首飞。首飞我们希望是一个成功的首飞,安全、成功。为了安全成功,我们会在地上做非常多的准备工作,要考虑到各种各样特情。如果有特情发生时,我们不要判断错,也不要处置错,能够在最短的时间内,做出一个正确的处置。”

在一份寄语中,蔡俊写道,“民机事业是民族的梦想,这是你的经历也是你的青春,轻易实现的算不得梦想,有梦想,就去捍卫它”。
