时速4千公里飞铁提出背后:技术未成熟,呼吁资本和政府介入

8月30日,中国航天科工集团(下称“航天科工”)在第三届中国(国际)商业航天高峰论坛上投下重磅,宣布已联合国内有关单位,开展了“高速飞行列车”的研究论证,时速最高可达4000公里。凭借这一超过3倍音速的速度,让公众直呼其为“飞铁”。

所谓的“高速飞行列车”,原理即是利用真空管道和超导磁悬浮技术,实现超音速的“近地飞行”,被誉为人类未来的“第五种交通方式”。而实际上,中国早在2000年前后就已引入真空管道磁悬浮概念,近二十时间内,外界对其却关注甚少,风头更是被硅谷“钢铁侠”埃隆 马斯克(Elon Musk)在2013年提出的“超级高铁”盖过。目前,在全球范围内,研究真空管道磁浮交通的国家有瑞士、美国和中国。

西南交通大学首席教授、长江学者特聘教授、超导与新能源研究开发中心主任赵勇在接受澎湃新闻采访时表示,“这项技术需要引起社会的关注。”赵勇认为,航天科工此时公开宣布这一项目,“不是说这个技术已经成熟了,而是需要产业部门介入,国家政府要有投入,把前期技术先开发出来。”

赵勇是中国高温超导领域的第一个博士,辗转意大利、澳大利和日本13年后,他回到西南交通大学,是西南交大材料科学与工程系长江学者特聘教授、国家首批外籍杰出青年基金获得者。彼时的赵勇认为,“西南交大是最适合搞超导磁浮研究的地方”。据赵勇透露,赵勇团队是国内首个国际性高速飞行列车产业联盟的成员之一。

此前的8月30日,航天科工方面表示,专门为“高速飞行列车”工程项目,联合了国内外20多家科研机构,成立了国内首个国际性高速飞行列车产业联盟,目前团队拥有相关领域的200多项专利。这个产业联盟也被称为真空管道磁浮研究领域的“国家队”。

赵勇还透露,“航天科工目前的整个方案、基本思路就是按照我们的书提出来,具体关于磁浮方面的设计是我们来帮助完成。”赵勇所指的书则是其2009年发表的《速车系统概论》,这是世界上第一本系统论述真空管道磁浮技术的专著。该书的另一作者为刘本林,据刘本林对澎湃新闻表示,他和赵勇为中国科学技术大学物理系同学,其本人于2005年接触真空管道交通。值得一提的是,在外人看来,刘本林是一个对新鲜事物充满热情的“民间科研爱好者”,并非在正规科研机构任职。
