中国青年报客户端广东珠海11月11日电(程铭 中青报·中青网记者 邱晨辉 文并摄)11月11日,第十五届中国航展开幕在即,记者在探展时看到了重型火箭模型,其中两级完全重复使用构型引发关注。这是重型火箭两级完全重复使用构型首次亮相中国航展。
中国航天科技集团一院总体设计部设计师陈子聿介绍,重型运载火箭体现我国更大更远、自主进出空间的能力,是我国综合国力和航天强国的重要标志。其任务场景涵盖深空探测与开发、大型空间战略基础设施建设等。我国重型运载火箭研制采用“系统规划,分步实施”的原则和“模块化、通用化、系列化”发展思路,形成由三级串联构型、两级串联构型、两级完全重复使用构型组成的系列化型谱,将分两个阶段实现重型运载能力和完全重复使用,覆盖近地到深空各类探测任务需求。
我国重型火箭构型首次亮相航展。
其中,第一阶段,将发展通用一子级、一次性二子级、氢氧三子级模块,全箭直径10米级,构建重型火箭基本型,该型火箭地月转移轨道运载能力不小于50吨、近地轨道运载能力不小于100吨,将大幅提高我国进出空间能力。第二阶段,将开展多适应性二子级研制,构建两级完全重复使用构型,大幅降低进出空间成本、提升进出空间效率,具备大规模航班化空间运输能力,建设世界领先的航天运输系统。
陈子聿介绍,重型火箭一级重复使用构型计划2030年首飞,两级完全重复使用构型计划2033—2035年首飞。

长征十号甲运载火箭模型也在此次航展亮相。该型火箭是我国正在研制的一款直径5米级一子级可重复使用运载火箭,是在长征十号运载火箭基础上通过模块化、通用化设计形成的衍生构型,具有高可靠、高安全等特点。载人状态下全箭总长约67.4米,载货状态下全箭总长约66.4米,起飞重量约750吨,起飞推力约892吨,一子级回收状态下的近地轨道运载能力不小于14.2吨,可满足新一代近地载人飞船、天舟货运飞船等载人航天发射任务需求。该型火箭计划于2026年首飞。
China Youth Daily client Zhuhai, Guangdong Province, November 11 (Cheng Ming China Youth Daily · China Youth network reporter Qiu Chenhui Wen and photo) November 11, the 15th China Air Show is about to open, the reporter saw a heavy rocket model when visiting the exhibition, of which two stages completely reusable configuration caused concern. This is the first appearance of the two-stage fully reusable configuration of the heavy rocket at the China Air Show.
Chen Ziyu, designer of the overall design department of the first Institute of China Aerospace Science and Technology Group, introduced that the heavy launch vehicle reflects China's ability to enter and exit space more and more independently, which is an important symbol of China's comprehensive national strength and space power. Its mission scenarios cover deep space exploration and development, and large-scale space strategic infrastructure construction. The development of China's heavy launch vehicle adopts the principle of "system planning, step by step implementation" and the development idea of "modularization, generalization and serialization", forming a series spectrum composed of three-stage series configuration, two-stage series configuration and two-stage fully reusable configuration, which will achieve heavy carrying capacity and full reuse in two stages, covering the needs of various exploration missions from near Earth to deep space.
China's heavy rocket configuration debuted at an air show.
Among them, in the first stage, the development of general one sub-stage, disposable two sub-stage, hydrogen and oxygen three sub-stage modules, the diameter of the whole arrow is 10 meters, and the construction of the basic heavy rocket, the rocket of the Earth-moon transfer orbit carrying capacity is not less than 50 tons, the low-Earth orbit carrying capacity is not less than 100 tons, will greatly improve China's ability to enter and exit space. In the second stage, the multi-adaptive two-stage sub-development will be carried out to build a two-stage fully reusable configuration, greatly reduce the cost of entering and leaving space, improve the efficiency of entering and leaving space, have large-scale flight space transportation capabilities, and build the world's leading space transportation system.
Chen Ziyu introduced that the first-stage reusable configuration of the heavy rocket plans to fly for the first time in 2030, and the two-stage fully reusable configuration plans to fly for the first time in 2033-2035.
A model of the Long March 10A carrier rocket was also unveiled at the air show. This type of rocket is a sub-stage reusable carrier rocket with a diameter of 5 meters, which is a derivative configuration formed on the basis of the Long March 10 carrier rocket through modular and universal design, and has high reliability and high safety characteristics. The total length of the whole arrow under manned condition is about 67.4 meters, the total length of the whole arrow under cargo condition is about 66.4 meters, the take-off weight is about 750 tons, the take-off thrust is about 892 tons, and the carrying capacity of the low-Earth orbit under the state of a sub-stage recovery is not less than 14.2 tons, which can meet the needs of the new generation of near-Earth manned spacecraft, Tianzhou cargo spacecraft and other manned space launch missions. The rocket's first flight is scheduled for 2026.
