“猎鹰9”运载火箭海上平台成功回收的分析及启示

Analysis and Enlightenment of Successful Retrieval of "Falcon 9" Rocket on Offshore Platform

为全面分析SpaceX公司垂直起降重复使用"猎鹰9"火箭技术水平和发展潜力,系统概括了SpaceX公司特点和"猎鹰9"火箭相关飞行试验,采用经验总结法剖析了SpaceX公司取得成功的深层次原因,研究了海上平台垂直回收的优缺点和重复使用关键技术。通过模型假定和仿真计算表明,"猎鹰9"重复使用火箭运载能力损失约30%以上、发射费用可降低30%;在此基础上提出"猎鹰9"火箭后续跟踪研究的主要问题,我国低成本运载火箭发展策略以及我国运载火箭技术发展差距等。

To comprehensively analyze the technical level and development potential of SpaceX＇s ＂ Falcon 9＂ rocket,this paper systemically summarizes the characteristics of SpaceX and the flight tests of ＂ Falcon 9＂ rocket,discusses the successful experience of SpaceX with Experiential Summary Method and considers the advantages and disadvantages of vertical retrieval on offshore platform and the key technology for reuse.By model assumption and simulation computation,the study results show that,the loss rate of carrying capability of the ＂ Falcon 9＂ is more than 30%and the launch cost may be reduced by 30%.And then,the paper brings out some key points which should be solved out in follow-up studies of ＂ Falcon 9＂ development,China＇s development strategy in low-cost carrier rocket field and the gap between China and the advanced countries in carrier rocket technology.
