China will develop large-diameter rocket meets Mars exploration mission | rocket _ news

To meet future mission needs, China will develop an arrow diameter up to 10 m, gross weight of 3000 tons of heavy launch vehicle, took off their structure, size and quality will exceed China's existing launch vehicle capability level.

Super large diameter heavy launch vehicle rocket structures create enormous challenges, from August 26 to 27th, China Academy of launch vehicle technology (hereinafter "the rocket") combined with Harbin Polytechnical University, zhongnan University unit in Harbin organized a collection a number of domestic industry experts and scholars of heavy carrier rocket manufacturing technology seminar.

Conference invited has rocket hospital Long Yuehao, and CSU Bell dig, and Xian traffic University Lu Bingheng, and Shanghai traffic University Lin zhongqin, and Hefei general mechanical Institute Chen Xuedong 5 bit engineering hospital academician and the more than 30 over domestic material, and forming and welding, professional aspects of experts scholars, around Super big size thin-walled structure forming, and Super big diameter ring pieces integration manufacturing, and super large thin-walled storage box Assembly welding, technology direction for Exchange research.

Long Yuehao Fellows reports

Will Shang, Long Yuehao Academician to participating representative for has entitled development heavy rocket support space power of report, described has heavy rocket of development background, introduced has heavy rocket of diameter and the engine of thrust volume level, based on big thrust liquid oxygen kerosene engine and based on big thrust solid help push device of two species rocket General technology programme envisaged, proposed has heavy rocket development key technology needs. Report, based on the characteristics of heavy carrier rocket Long Yuehao, academician of the potential future application requirements are analyzed, indicating heavy carrier rocket for China's space activities, accelerating the development of space applications are of great significance.

Rockets Vice President Wang guoqing, made a presentation

Rockets Vice President Wang guoqing made a presentation entitled the report on heavy rocket tank manufacturing considerations, through the review of foreign heavy tank development process, proposed a lightweight and efficient design and manufacturing routes top design, precise/accurate connection/heavy tank of launch vehicle development implications in three areas. In system summary active and the new rocket storage box development experience and the technology accumulated precipitation of based Shang, analysis has heavy rocket storage box manufacturing by needed solution of key technology difficulties, integrated technology, and economic, and cycle, and risk, factors, proposed has "two step go" of heavy rocket storage box development thought, and proposed produced, and learn, and Institute achieved depth cooperation, common research cracked Super big diameter storage box manufacturing technology problem.

Fellow expert visited Harbin national defence science and technology laboratory

Meeting heavy rocket very large diameter arrows structure design, material selection and manufacturing, non-standard equipment research and development provides many good ideas for heavy launch vehicles play a positive role in promoting the work.

According to understand, heavy rocket is for meet China future manned Moon, and Mars detection, task needs and is started of space major technology engineering, is China implementation space development strategy, and effective expand space industry development space, and sharply improve into space capacity, and promote space technology overall level improve of necessary guarantee, on upgrade space development level, and improve engineering technology integrated strength, further enhanced China in international social of political influence, improve integrated power has important of strategy meaning.

中国将研制超大直径运载火箭 满足火星探索任务|重型火箭_新闻资讯

　　为满足未来任务需求，中国将研制箭体直径达10米、起飞质量达3000吨的重型运载火箭，其结构尺寸和起飞质量均将突破中国现有运载火箭能力水平。

　　应对重型运载火箭超大直径箭体结构制造带来的巨大挑战，8月26日至27日，中国运载火箭技术研究院（以下简称“火箭院”）联合哈尔滨工业大学、中南大学等单位在哈尔滨举办了一次汇集多位国内相关行业权威专家和学者的重型运载火箭制造技术研讨会。

　　会议邀请了火箭院龙乐豪、中南大学钟掘、西安交通大学卢秉恒、上海交通大学林忠钦、合肥通用机械研究院陈学东5位工程院院士及30多位国内材料、成形和 焊接等专业方面的专家学者，围绕超大尺寸薄壁结构成形、超大直径环件一体化制造、超大型薄壁贮箱装配焊接等技术方向进行交流研讨。

△龙乐豪院士作报告

　　会上，龙乐豪院士向与会代表作了题为《研制重型火箭 支撑航天强国》的报告，阐述了重型运载火箭的研制背景，介绍了重型运载火箭的直径及发动机的推力量级，基于大推力液氧煤油发动机和基于大推力固体助推器的 两种火箭总体技术方案设想，提出了重型运载火箭研制关键技术需求。报告中，龙乐豪院士还结合重型运载火箭的特点对未来的潜在应用需求进行了分析，表明重型 运载火箭对于提升中国空间活动能力，加快空间应用开发的步伐都有着重要意义。

△火箭院副院长王国庆作报告

　　火箭院副院长王国庆作了题为《重型火箭贮箱制造的若干思考》的报告，通过回顾国外重型火箭贮箱研制历程，总结提出了轻质高效设计、制造路线顶层设计、精 确成形/成性/精准装配连接三方面的重型运载火箭贮箱研制启示。在系统总结现役及新一代运载火箭贮箱研制经验及技术积累沉淀的基础上，分析了重型运载火箭 贮箱制造所需解决的关键技术难点，综合技术、经济、周期、风险等因素，提出了“两步走”的重型运载火箭贮箱研制思路，并提议产、学、研实现深度合作，共同 研究破解超大直径贮箱制造技术难题。
