海上垂直回收运载火箭发展现状与关键技术分析OACSTPCD

The recyclability and reuse of launch vehicles not only can reduce the launch costs,but also can increase the launch density to meet the needs of high-density launches.It is a technology that must be developed by humans to explore space.The vertical return-to-sea recovery method has a high-precision and high-stable landing point,by which both the threat to the safety of the people in the landing area and the impact of insufficient rocket carrying capacity can be reduced.Since the sub-stages of the"Falcon 9"rocket were successfully recovered vertically at sea and reused,researchers from various countries have paid attention to and explored the vertical recovery technology of rocket sub-stages at sea.In this paper,the advantages and characteristics of maritime vertical recovery launch vehicles are described.Then,the development status of maritime vertical recovery launch vehicles is sorted out,and the key technologies included in the process of recovering a rocket at sea are analyzed.Finally,the development trends of maritime vertical recovery launch vehicles are summarized.
