第六百一十二章 震颤(1 / 2)

大国航空 华东之雄 1063 字 2022-04-26

一般的首飞,都是不回收起落架的,而且,仅仅是绕机场一周,就可以下来了,只要验证飞机能飞起来,能落下,这就是一个巨大的进步,一个历史性的时刻,首飞就会画上圆满的问号!

这次的首飞,自然也是如此,按照原定计划,飞机爬升至1000米,左转平飞,沿着飞机城的山川环绕通场落地。

但是,当刚刚拉起来之后,秦风就感觉到有些不对劲了。

自己的手,怎么在抖?

如果是第一次上飞机的时候,可能会因为紧张而身体发抖,手也会抖,这都是正常的,但是问题自己已经不是个新手了啊,自己的手怎么会无缘无故地发抖?

他低头,看了一眼仪表板,发现仪表板似乎有些看不清了,怎么回事?

“001,我感觉到有些发抖。”这个时候,后舱的杨林也开始报告了。

秦风是驾驶飞机的,后面的杨林那里没有操作杆,现在,他也感觉到有些发抖了,秦风顿时就在心里咯噔了一下,不好!

结构性震颤!

虽然飞机在发抖,但是和以前遇到过的那种飞行员诱发震荡,是完全不同的,那种诱发震荡,是因为自己在调整飞机的操作的时候,调整过度,或者说是飞控的反馈太灵敏出现的,现在呢,自己的飞机根本就没有操作,仅仅是最普通的爬升,就开始发抖了,这个发抖,现在越来越剧烈,随着速度的增加而加快,这就是更可怕的结构性震颤!

当初在滑跑的时候,就有过这种感觉,但是当时太轻微了,谁都没有当一回事,但是现在,这个故障,在起飞之后,就体现出来了!

如果飞机飞进了失速尾旋,就会出现机身的颤动,当颤动的厉害了之后,甚至会让整个飞机解体,那个时候,飞行员连跳出来的机会都没有,因为飞行员和飞机是一体的,当钢铁的战机都会被颤得散架的时候,里面的飞行员,也早就跟着血洒长空了!

那是失速尾旋之后的特殊情况,但是现在呢?飞机的状态还是保持正常的,飞机就开始震颤了,很明显,这是设计的缺陷了。

试飞是高风险的,在设计过程中的各种问题,都会在试飞中暴露出来,这就考验试飞员的本事了,如果试飞员没有正确操作,那么,就可能造成最可怕的结果。

现在呢,怎么办?

跳伞吗?

现在跳伞,那肯定是有机会的,两人都能够逃脱性命,但是,这架飞机就摔了,首飞就摔机,是对型号的一个沉重打击,甚至可能回到导致整个项目失败也说不定。

必须要把它飞回去,只有飞回去,才能够给工程师们提供样品,让他们研究,到底问题出在什么地方!

秦风下了决心。

要飞回去可不容易,毕竟,起飞之后,要四次转向,完成一个圈,才能够返航降落,现在呢,第一次的转向还没有开始呢,他还在远离机场!
