Abstract: Launch vehicles are the main means for a country to enter space, and its manufacturing level is crucial to the process of controlling space. As the main part of the launch vehicle, the structure of the rocket body is the key to rocket manufacturing. After decades of development, the rocket body manufacturing technology has gradually shifted from a manual operation-based model to a green and automated technology-based model. According to the manufacturing situation of the rocket body structure at home and abroad, this article gives a detailed introduction to the key technologies and equipment in the rocket body structure manufacturing process, including sheet metal forming, milling processing, drilling and riveting, welding and rocket body docking. The main process summarizes the domestic and foreign gaps and application difficulties of related technologies, and provides a reference for the development of my country's launch vehicle rocket body structure manufacturing level.
