美航客机下坠 宛如“自由落体”一般颠簸不停

2017-08-10 09:43:39   北京晚报

美国航空公司一架由希腊雅典飞费城的客机,8月5日降落前遇上超强乱流,如“自由落体”般颠簸下坠,机上的人与杂物顿被抛到半空。事后机舱内乱成一团,连机舱顶也沾上饮料,至少10人受伤送院。

现场图

肇事客机航班编号为AA759,载有287名乘客及12名机组人员。在降落费城国际机场前30分钟,机舱服务员才刚分发饮品和食物,客机便遇上强劲乱流,事前却未有任何预警。混乱中,饮品横飞,有人更直撞机舱顶,服务员慌忙叫乘客扣上安全带。

从一名冯姓乘客(ErvinFang)拍的画面可见,“灾难”过后杂物散落一地,机舱顶多处沾有刚才倒泻的饮料污渍。据报有机舱服务员肩膀撞至脱臼,7名机组人员及3名乘客受伤送院。机长事后指乱流之强劲出乎意料。美国航空发声明称,正在照顾受影响的乘客。

飞机万米坠落会怎样

一、飞机为何会瞬间解体?

空中解体(俗称散架),是指飞机(或其它飞行器)由于各种原因,比如气流、撞击、爆炸、操作不当、超过最大过载等,机体发生结构性损坏,从而导致机身破裂,由于飞机机舱是增压的,内部压力会将飞机撕裂,然后整个机体就变成碎片。原理就好像是气球爆裂,也好比手里拿着一个装满水的薄袋子,拼命地甩动,最终袋子会承受不了水的重力和离心力而自行破裂。

二、解体时飞机状态怎样?

飞机崩解状态:飞机在9000多米以上高空解体,有可能崩解成四节较大的机块,分向坠落。

乘客抛出状态:乘客被抛出机舱的一瞬间已昏迷,高空至坠落海中的几分钟过程中,大多乘客毫无知觉。因为超过9000多米的高空,气压只有地面的30%,人体从原本密封、加压的舒适机舱中突然被抛出,不但无法呼吸,体内的空气更因失压向外溢散,瞬间严重昏厥过去。

三、坠落会加速残骸分解吗?

至今尚未找到确认的残骸,有网友疑问,会是万米坠落的过程加速了各个材料分解吗?一物理学专业人士分析,在不了解飞机上所有材料性质、熔点等数据的前提下,具体情况不好推断。但大致说来,如果飞机解体时有大块残骸,万米高空坠落不会改变太多。

乘客在坠落过程中,也不会被“分解”,但会窒息而死或冻死。

另外,乘客坠海前即使还活着,在冲力加速度的猛力下撞击海面,大部分乘客全身粉碎性骨折。

四、飞机会突然变成“粉末”吗?

1、机械故障?不会

2、炸弹炸碎?有可能

有航空公司国际航线机长曾分析,如果恐怖分子不是一个人,把几个炸弹的爆炸时间调整在同时,结果会更可怕。如果是行李里的炸弹,它会在货舱,只会把飞机局部炸裂、炸碎,也可能引爆燃油。

上述物理学专业人士分析称,炸成“粉末”导致无法寻找的情况,需要较大炸药量,甚至要在不同部位安放炸弹才行。
