时速4000公里的高速飞行列车将要来临!准备好了吗?

新华社武汉8月30日电  题:时速4000公里的高速飞行列车将要来临!准备好了吗?

新华社记者谭元斌、胡喆

从30日在武汉召开的第三届中国(国际)商业航天高峰论坛上,传来一条举世瞩目的消息:中国航天科工集团公司将研制最高时速达4000公里的高速飞行列车,实现超声速“近地飞行”。

4000公里的时速,相比传统高铁提升了10倍,相比现有民航客机提升了5倍。这么快的列车,有可能吗?有意义吗?受得了吗?带着这些疑问,记者采访了中国航天科工集团公司高速飞行列车项目技术负责人毛凯。

  有可能吗?

目前,包括中国航天科工集团公司在内,世界上仅有极少数几家企业对外宣布开展时速大于1000公里的运输系统研究。而且,国外企业的目标时速多在1000公里左右,而中国航天科工集团公司却把终极时速定在了4000公里。航天科工也是全球首个提出超声速地面运输系统的企业。

据毛凯介绍,高速飞行列车是利用低真空环境和超声速外形减小空气阻力,通过磁悬浮减小摩擦阻力,实现超声速运行的运输系统,是超声速飞行技术和轨道交通技术的有机结合。

“我们现在有非常好的经济条件、技术储备、人才储备、实验条件和政策环境,天时地利人和。”毛凯说,航天科工拥有丰富的重大项目系统工程实践经验和技术积累,具有大工程必备的仿真建模和大系统试验能力,以及国际一流的超声速飞行器设计能力,这些为高速飞行列车项目建设提供了重要的基础。

记者了解到,中国航天科工集团公司高速飞行列车项目联合了国内外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。

而且,我国高速飞行列车采用的技术路径和国外的不一样,国外采取的悬浮方式需要车轮先跑起来,达到一定速度才能悬浮起来,而我国采取的高温超导磁悬浮方式属于被动悬浮方式,没有初速度也能悬浮起来,不需要用车轮。

“交通产业是一个国家战略性的产业。”毛凯说,随着高速飞行列车产业化技术的发展,成本会越来越低,“这是一个必然的趋势”。

  有意义吗?

在慢生活成为一种社会需求的前提下,去追求极致的速度,有意义吗?

出席第三届中国(国际)商业航天高峰论坛的一些专家认为,讨论这个问题,不如问2小时环游全国、半天环游世界是否美好。
