伙伴们,这个是什么机型?波音七六七还是七五七?估计百分之九十的小伙伴都认不出来,本期视频呢,就教大家怎样区分波音七五七和七六七。 其实啊,这两款飞机啊,他们的外形实在是太相似了,相信很多小伙伴和我一样都是经常把这两款飞机给弄混。那么呢,今天呢,我们开箱这款模型,顺便就给大家来分享一下这两最大的区别在哪里,就是那个外观上面让我们最直白的一下子就能区分的出来。 先把这款模型打开给大家看一看,我手上的这款模型呢,他是 vt 的一比四百的波音七六七。下面呢我们来看一下 vt 的这款模型做的到底如何, 它这个包装采用的是一个一个开窗式的一个包装,通过外包装就能很直白的看到里面的模型,这个模型呢也是有送一个底座和支架的来,我们现在把这个模型拿出来给大家 看一看。这款模型呢是以色列航空的啊,整个机身为白色为主,比较简洁大气。来我们看一下细节, 整个模型细节还算可以,尤其是起落架部分,看一下他的前置起落架,他的发动机不是镂空的,不过这个发动机这个细节嘛,我感觉有待改进,感觉那个叶片纹理不是很对啊,而且他这个起落架是没有垂旋的,我买这款模型也中奖了,他的肌肤下面有微微的一个起疹的一个情况, 整个模型比例一比四百,他的模型长度差不多不到十四厘米,也就是十三点八厘米左右的样子,他的这两边一点宽度呢,差不多是十一点九厘米左右,这款模型最大的亮点还是他的那个机身印刷,这个一印刷是相当出色的,而且整个机身的形体还算可以,基本上是没有所谓的。 好,我们说了这个模型,我们再来说一下这个畸形吧。首先我手上拿的这款模型呢,他的机型是波音七六七,当然这个是我告诉大家畸形了,如果我不告诉大家型号的话,就这样单凭靠直觉,大家看能不能 看得出来他是哪个型号,估计很多小伙伴和我一样,基本上是缺不出来的,因为这两款机型实在是太像了。那么今天呢,就教大家一个最直观最简单的一个方法,来辨别播音七六七和七五七的区别, 咱们最大的区别就是在他们这个机头这里,大家看这个图片,播音七六七呢,他的机头稍微就是说偏远一点点, 看起来鸡头稍微有那么一点尖,而波音七五七呢,他的鸡头啊,就是上面弧度大,下面弧度小,整个看起来就是鸡头偏下面一点是扁平的。好了,今天这个小技巧就分享给大家了,不知道大家记住没有,没记住的小伙伴可以把这个视频再看一遍, 多看几遍大家就印象就更加深刻了。好了朋友们,本期视频就这样了,感谢大家的观看,你们想我开箱什么样的模型?欢迎大家在评论区进行留言,别忘了关注一波数字三连,我们下期视频再见吧,拜拜。

we had talked before about paperwork and the crew meals on an airplane and i just wanted a touch base on one of the strangest features of the seven fifty seven and that is all the dimming switches so we're gonna go through those really quick two lights down here called grimes lights one here and one just behind me at the second observer seat and those allow you to see if your kit bag continuing up we've got map lights that shine down on your approach plates we've got a flood light that shines underneath the panel, we've got panel lights that bring up the instrument panel lights we've got a chart light right down here and the lights up this plate overhead, we've got glare shield light lights up this glare shield here in the front panel for the autopilot functions and a light for that which brings the lights up, just below it so two lights that will handle this we've got isle stand lights again two lights that will light up the internal lights as well as the overhead lights shining down on that isle stand we even have circuit breaker lights that light up the circuit breakers behind us we have an overhead panel light that lights up the real stats behind the instruments we have a dome light that sets the mood lighting just above our heads here it's quite nice and then there's one more real step way up here this is the irs real step just dims and brightness this one little digital display and that's it that's its only function we have a mechanical checklist this is something that our airline uses and believe it or not that has its own light in the front we have icast lights and there's two of them and there's two switches to control them individually like we also have a tea cap that has its own bright and dimming switch over here on the fms's each fms has a bright and dim light and also down here we've got controls for the attitude indicator and the map display and we can also control the weather radar it can brighten the weather or turn it down and dim it we've got three of those switches here we have also three more switches on the other side as well finally on the other side of the captain he's got four more of these switches plus the two grimes light switches as well now on the triple seven if you put each one of these lights in an indentation kind of a straight up twelve o'clock position you can actually turn one knob and that will control all the lights at once so those are the dimming switches for the seventy seven just in case you need to know i don't know why who knows but you go out and buy a sep except for yourself that's it either you can take external power and yes quit it's also to know if you feel this good is to crack a finish let's see we have seventy point seven and let me take a look fuel yeah that's great that feels good okay thank you i will bring you the fuchsin couple of minutes okay great。

君主航空三九零号航班在失去精益和扰流板的情况下惊险降落在里斯本。调查员立刻钻进了驾驶舱下方的电子设备舱。这里是飞机的大脑,密布着计算机和电缆。 在左侧主发电机系统和 p 七零配电盘之间的电线束中,他们找到了故障源头。这里的电线不仅被严重烧毁,而且调查员发现这片区域竟然充满了液体。 经过分析,这些液体不是燃油,而是前厕所流出来的清洁溶剂。原来,位于电子舱上方的厕所排水管发生了泄露,具有腐蚀性的兰枝顺着缝隙滴落到了下面的电线树上。 但问题来了,飞机的电线都有绝缘层保护,滴点水怎么会爆炸?问题就出在这架七五七使用的绝缘材料上。据先亚案商业名称叫 capitan 巨仙亚案,是杜邦公司六十年代发明的。它轻薄、强度高,能耐受从接近绝对零度到四百摄氏度的高温,曾是 nasa 航天器的御用材料。为了给飞机减重,波音、麦道等厂商疯狂使用这种材料。但巨仙亚案有一个致命弱点, 他在特定条件下会降解。调查发现,这些电线在之前的维护中,因为打印标记,绝缘层受到了微小的物理损伤。这种损伤加上巨仙亚胺本身容易受潮气和热量影响而老化的特性,让它变成了一颗定时炸弹。 当厕所的清洁液滴在这些老化破损的巨仙亚胺电线上时,引发了失电弧。这不仅仅是短路,巨仙亚胺在电弧的高温下会发生化学变化, 被烧焦的绝缘层本身变成了导体,这叫电弧跟踪,于是电火花顺着电线一路烧下去,温度高达数千度,甚至融化了里面的铜芯,留下了融化的铜珠。 这就是为什么机长听到爆炸声的原因,如果不及时降落,这场由厕所漏水引发的电线之火,很可能会酿成不可控的空中火灾。而且这并不是巨仙压案第一次惹祸,也不是最后一次。


国航旗下中国国际货运航空的七五七货机现在已经全部退役了,即将取代他的是国航的一批三三零客机,将要改成货机。现在国内还有顺丰航空、圆通航空、邮政航空、西北货运航空、中航货运运营着七五七货机, 大家见过哪些航空的货机没有了?
