世界最大飞行器“瘪了” 试飞时坠毁气体泄漏

2017-11-20 01:10:12   中国青年网

据英国媒体报道,世界最大的飞行器“天空登陆者”于当地时间18日早晨在一片田地上坠毁。当时,飞艇正在试飞。一名女子因此受伤,由于担心气体泄漏带来的危害,附近道路被封锁。

现在,还不知道它坠毁的具体原因。不过,这种奇特的飞行器可能让你感到很好奇。这到底是个什么样的家伙?

这家伙到底有多大

作为世界上最大的飞行器,想知道它到底有多大吗?据介绍,它的身长大约93米,体宽有44米,机体的高度则有26米,相当于6辆双层大巴车。

如果你对这个尺寸没有概念,可以对比一下现在世界上最大的宽体客机空中客车A380和世界上最大的运输机安225。

著名的A380机长73米,给人们带来的视觉效果已经足够震撼;世界最大的运输机安225则比A380还要长10多米,达到了84米,但在它面前,还是要小一圈。

不过,与A380和安225的超大机体是用来载客和装货不一样,它的机体尽管更加硕大,但这些空间的绝大部分并不能用来载客和装货,因为它的飞行原理更接近飞艇,所以这个由超强碳纤维打造的巨大身躯里,充满的是用来为这个飞行器提供飞行升力的氦气。如果把这个“气球”里的氦气汇聚起来,足足能填满15个标准游泳池。

这家伙有什么特点

这一飞行器首次试飞前,英国混合飞行器公司首席执行官史蒂芬?麦克伦南一直在飞行模拟器上练习操作飞行器,他说:“它的操作非常简单。”

这个操作简单的世界上最大的飞行器,其实设计的初衷是做军事用途的,用来作为美军设计的一个空中监视平台。不过因为美国削减军费,不得不终止了这个项目。

不过,以军用为目的的该项目终止后,人们发现这个已经初具雏形的飞行器,其实完全可以在民用市场一显身手。于是,在贝德福德郡卡丁顿的一座机库里,这个项目重新启动,并进行了进一步的改造与研发,直至首飞。

它采用了类似飞艇的结构,由硕大的氦气仓提供大部分升力,另外配备的四台可变推力方向的350马力涡轮增压柴油发动机,提供额外的升力和平飞的动力。设计的飞行速度为148公里,最大载重量为10吨。如果在空中手动进行航行,它可以连续进行5天的不间断飞行,如果改成无人驾驶的自动航行模式,则能在空中连续两周不间断地飞行。

这家伙究竟能干啥

这个世界上最大的飞行器和一般飞机不同,它的起飞和降落都不需要跑道,能像直升机一样垂直升降。同时起降也不局限于陆地,水面、冰、沙漠等平面都行,因此它能把货物或人运送到一些交通欠发达的偏远地区,例如沙漠、丘陵等地带。另外,设计者还希望这个世界上最大的飞行器将来在休闲航行、空中监测等方面都大显身手。

目前,除了试飞的载重10吨的机型,设计者还打算开发载重50吨的机型。在它的设计用途中,还有项叫做“空中起重机”的设想,就是用它在偏远地区的石油、矿山等建设中,运送和搭建大型机械和设施。要知道,由于耗油量很小,它的使用成本可比大型直升机便宜的多。比如大型直升机“米-26”在救灾时每小时的飞行费用大约要13万人民币,而它则只需要个零头。

当然,由于身体里充满了氦气,在大风的日子里,它会遭遇很大的麻烦。
