时速4000公里“飞铁”曾被院士推崇 因资金问题停滞

2017-09-12 09:01:18   中国青年网

问及原因,张耀平只表示,“没什么原因,只能想是因为水平还不够吧。”

值得一提的是,张耀平主动谈及,此前有业内人士暗指其“热衷于把这些纸上谈兵的东西申报专利、组建公司、成立研究所、出版书籍,而不去认真探讨为什么不能实现”,背后也有苦衷,“如果有经费,我何尝不想做实验?没有基金、没有实验室、没有各方面的力量,我怎么做?”

两院院士提出设想

中国真空管道交通的一次标志性事件是2004年中国两院院士(中国科学院、中国工程院)沈志云的公开支持。沈志云当时为西南交大牵引动力国家重点实验室教授。

据一名知情人士对澎湃新闻(www.thepaper.cn)透露,沈志云对真空管道的思考始于2004年暑假期间。“9月份一开学,西南交大就召集了部分老师开了一个非常重要的会议,在这次会议上沈院士提出了对未来交通发展的一些思考。”

彼时,上海磁悬浮列车已投入使用,高铁在2004年也已开始引进技术。还有什么交通方式可供选择?堪称中国交通智库的西南交大又将如何引领前沿?

沈志云在上述会议上提出的便是真空管道交通。同年12月18日,沈志云发起了一场“真空管道高速交通”院士研讨会,有7位院士到场支持参会。这场研讨会的成果最终以论文的形式发表在2005年4月的《西南交通大学学报》,这篇论文也让学术界认可是沈志云提出“真空管道高速交通”的设想。

沈志云在论文中提出,在地表稠密大气层中运行的高速交通工具,最高经济速度不超过时速400公里。然而,实现更高速度确有客观需要,也是交通科技工作者孜孜以求的梦想。实现更高经济速度的一个可能的途径是采用真空管道。

沈志云当时对中国真空管道高速交通的战略定位为600-1000公里/时的超高速地面交通,是目前地面高速交通的延伸和补充。并在论文中提出分为四个阶段推行,即从2005年开始,5年达到小比例模型推出,10年全尺寸模型,15年达到实验线路,25年即2020至2030年实现运营线。

然而,沈志云设想也仅仅止步于设想,后续也没有实质性推动。

值得一提的是,张耀平这位真空管道领域的概念引入者,在西南交大期间,并没有得到沈志云的支持。

据张耀平对澎湃新闻(www.thepaper.cn)回忆,在2004年12月那场院士研讨会之前,他才第一次和沈志云有了真正的“接触”。而在此之前,尽管张耀平几次希望能得到沈志云的认可和支持,但均被其通过电话等放方式拒绝。“那时候就想,如果要真正推动真空管道交通,沈院士能出面支持当然是最大的力量。”
