With the increase in the types of liquid launch vehicles, the contradiction between the production capacity of the rocket storage tank and the task demand is more and more prominent, and the non-uniform technical status of the storage tank bottom of each model seriously restricts the enhancement of the industrialization capacity of the tank bottom production. The bottom of the liquid launch vehicle storage tank carries the propellant, bears and transmits the axial and radial loads along the body of the rocket, and is one of the determining factors of the advanced and reliable space equipment. In order to solve the contradiction between the production capacity of rocket storage tanks and the mission demand, this paper carries out the construction of storage tanks based on the opening characteristics and bearing capacity of the storage tanks in service, and carries out the construction of storage tanks based on the profile. It is parameterized by studying the connection between working conditions, carrying capacity and tanks bottom thickness. The distribution of openings and the thickness of the bottom of the storage tanks are unified to realize the productization of the storage tanks. The complete design process of tanks bottom unification, tanks bottom thickness design and automated modeling is integrated into the automated design platform of storage tanks box bottom, which provides new design ideas and methods for the research and development of storage tanks bottom. It is conducive to rapid selection, accelerating the liquid rocket research process, and enhancing the ability of productization of tanks bottom production.
