航天科工开展高速飞行列车研究论证 最高时速可达4千公里

2017-08-31 19:31:03   央广网

央广网北京8月31日消息(记者张子雨 实习记者崔丹萍)据经济之声《天下公司》报道,在很早的时候,火车的时速大约在几十公里的水平。现在的高铁,时速可以达到350公里。那么,火车的速度最高可以达到多少呢?这个问题的答案,可能超乎你的想象。

在昨天举行的第三届中国(国际)商业航天高峰论坛上,中国航天科工集团宣布,已开展高速飞行列车研究论证。这种高速飞行列车,最高时速可以达到每小时4千公里。这也就意味着,它的最高运行速度比传统高铁提升了10倍,甚至比现有民航客机也提升了5倍。举个例子,北京距离武汉约1152公里,目前,从北京出发的高铁需要5多小时才到武汉。然而,在不远的未来,北京到武汉可能只需要30分钟。

4千公里的时速是什么概念呢?我们来做一番对比。到目前为止,飞行速度最快的客机之一是法国的协和式客机,这也是一种超音速飞机。这种飞机的最高时速,也不过是每小时2300公里。只有正在研制的高速飞行列车的一半左右。每小时4千公里,这个速度大约是音速的3倍。

那么,这种列车的安全性如何呢,这么高的速度,人坐在上面受得了吗?对此,中国航天科工集团“高速飞行列车”项目负责人毛凯表示,列车的安全性,是有保障的。

毛凯说:“安全性是我们考虑的首要问题,系统的安全性与它分系统的迭代是有关系的,你要分析每一个分系统的安全性,然后迭代出来整个系统的安全性,这就对我们的设计和验证提出了很高的要求。目前像这种新的领域没有一个完整的标准体系,我们现在也参考了一些现有的标准体系,我们也会根据我们的需求来制定一些标准体系。加速的时候它是按照人能够承受的速度慢慢加的,然后到一定速度的时候它就开始巡航,也就是基本上按照一定范围的速度航行,在减速的时候,也是按照人承受的范围慢慢减。”

这样的高速列车投入运营之后,运营成本如何,普通人是否能坐得起呢?毛凯告诉记者,应该从更广泛的范围来讨论“高速飞行列车”的成本和收益。

毛凯:“应该用半个小时或者一个小时耗费的成本和用五个小时、六个小时的成本作比较,而不是单纯的用绝对票价去算。它给你省了时间,速度又快距离又远,它带动的相关经济比它的投入是要大的。它是一个复杂的大系统工程,所以我们现在也在反复确认,我们现在已经有了一个初步的估算,但是我们需要对老百姓负责任,我们需要反复的迭代核算之后才会公布这样的事情。”
