首款国产重型火箭垂直转至发射区 11月择机发射(图)

2016-10-31 11:21:05   中国军网

10月28日,首次实施飞行任务的我国最大推力新一代运载火箭长征五号,在海南文昌发射场完成技术区相关工作后,垂直转运至发射区,计划于11月初择机发射。

作为我国运载能力最大的新一代运载火箭长征五号,集成了多项最新的航天技术,首次采用5米直径箭体结构,首次使用无毒无污染的液氢液氧与液氧煤油发动机组合起飞方案,全新研制高可靠的控制系统,对我国运载火箭发展具有升级换代的里程碑意义。

垂直转运的顺利完成,标志着长征五号运载火箭首飞任务正式进入发射阶段。目前,文昌航天发射场系统和测控通信系统已完成执行此次任务的相关准备工作。

长征五号计划于11月上旬择机发射。它首次采用5米直径箭体结构,首次使用无毒无污染液氢液氧与液氧煤油发动机组合起飞方案,全新研制高可靠的控制系统,对我国运载火箭发展具有升级换代的里程碑意义。

长征五号系列火箭的主要目标是满足在未来20-30年中国到达近地轨道和同步转移轨道任务的大型有效载荷要求。CZ-5项目最初于2001年2月宣布。然而,资金直至2007年才最终被批准,由中国东北展会期间被开发商透露。

在长征五号运载火箭和位于海南岛的海南文昌航天发射场落成后,中国将具备25吨的近地轨道运载能力和14吨的地球同步转移轨道运载能力,可发射20吨级长期有人照料的空间站、大型空间望远镜、返回式月球探测器、深空探测器、超重型应用卫星等。

长征五号是中国第一个从总体到系统均采用全新技术的大型液体运载火箭家族。

长征五号的设计思想以通用化、系列化、组合化为重点。可搭载两种专门为其设计的火箭发动机,分别为推力为120吨的YF-100液氧煤油高压补燃循环发动机和推力为50吨的YF-77氢氧发动机。
