独家揭秘!太空“快递小哥”天舟一号货箱里都装了啥?

2017-04-22 22:18:27   央视网

央视网消息:4月20号傍晚,在中国文昌航天发射场,搭载着天舟一号货运飞船的长征七号遥二运载火箭点火升空,中国首单“太空快递”正式发出,已经送达天宫二号。“只运货,不送人”的太空快递小哥天舟一号,为天宫二号带去了6吨左右的货物和推进剂,大大小小有100多个货包。那么,这些货包里都装了些啥?这么多货包的摆放有啥讲究?我们的记者特意请来了为天舟一号设计货舱的工程师,为您独家揭秘。

央视记者:现在的快递,送什么的都有,好多都是我赔不起的易碎品,这都得精心打包好,摆好了码齐了,这趟货才能送得稳当。这个大货箱里,我是希望它装的越多越好,只要我的小车拉得动,它装得越多,我送货的效率就越高。

天舟一号货运飞船上有着一个在世界货运飞船当中最能装的一个大货舱,它一次性可以将6.5吨重的货物运上太空,其中有一项指标是评价货运飞船装货能力的,叫做载货比,天舟一号的载货比达到了0.48,也就是说整个飞船将近一半的重量都可以用来装货,这已经达到了世界上的一个先进水平。

有了世界级的运货能力,快递小哥天舟一号的第一次任务,又带了哪些东西呢?飞船工程师,是比航天员更早体验在天舟上取快递的人,被人们称为不上天的航天员。他就见证了天舟一号装货的全过程。

当然,这些东西在货舱里,也不是杂乱无章的堆放着的,而是安放在像超市货架一样的货柜里。此外,还可以通过这样的外挂包,挂在舱壁上,进一步充分利用天舟一号巨大的内部空间。

航天科技集团五院天舟一号飞船工程师 郭军辉:我们现在的话反正就是最大程度的考虑航天员载轨的使用顺序、使用的频率了,包括根据货物的不同,比方说你像吃的东西,为了延长它保存的时间什么的,我们会给他布置在一个温度比较低的地方。
