中国可重复使用火箭方案首次公布 突破关键技术

2017-06-08 16:00:09   央视新闻客户端

在今天上午的2017全球航天探索大会上,我国首次向全球公布了正在进行的可重复使用运载火箭概念方案。我国目前正在开展的重复使用运载火箭技术研究,包括垂直起降方案和伞降方案,目前这两个方案经完成部分试验验证,一些关键技术已经突破。

中国航天科技集团一院科技委主任鲁宇:在重复使用技术上,我们的基本观点是要符合我们中国发展的国情,怎么能够真正实现低成本。重复使用的目的是为了低成本,我们要把这两个问题统筹好,才能确定未来我们究竟走什么样的方案。

此外,此次大会上,我国还公布了正在进行关键技术攻关的重型火箭和新一代低成本中型运载火箭长征八号的最新进展。

中国航天科技集团一院科技委主任鲁宇:重型火箭瞄着2028年到2030年前后首飞,主要用于未来的深空探测,特别是建立月球基地,载人登月等方面的需求。长征八号主要运用了我们现有已经成熟了的技术,可以大大降低研发成本,在新一代火箭里面提供一个相对成本比较低的运载火箭。最快在2018年可以实现首飞。

中国运载火箭:降成本将“走自己的路”

有数据显示未来十年,每年都会有3-400颗卫星进入太空,加上各航天强国将实施的近地轨道开发,深空探测等计划,降低进入空间的成本成了越来越多人关注的话题。在国外可回收运载火箭逐步走向应用的同时,走自己的路,发展适合国情的低成本火箭,成了中国航天专家们的共识。

就在不久前,著名的美国探索公司刚刚完成了一次里程碑式的发射。即首次成功发射一艘重复使用的龙飞船,并且再次实现了运载火箭一级的陆地回收。此前,这家来自美国的民营航天企业也曾实现了回收火箭的再次发射升空,这让人们相信依靠可回收航天技术,可以大幅度地降低进入空间的成本。不过,在一场关注低成本航天的讨论中,中国的火箭专家却表示,实现低成本,重复使用并非唯一出路。
