Description

Technical Field

[0001] This utility model relates to the field of rocket shell technology, and in particular to an outer shell of a rocket storage tank. Background Technology

[0002] The rocket propellant tank shell is a core component for rocket propellant storage and structural support. It is mainly used to store the fuel (such as liquid hydrogen, kerosene, and methane) and oxidizer (such as liquid oxygen) required for rocket flight. At the same time, it must withstand extreme conditions such as aerodynamic loads, cryogenic environment, vibration and shock during flight. Its design, materials and manufacturing level directly determine the rocket's carrying capacity, reliability and cost.

[0003] Existing rocket storage tank shells are typically large in size. During manufacturing, a long outer shell is divided into multiple circular sections. The adjacent circular sections are then positioned vertically and horizontally and welded together. This process requires large processing equipment, and the production of multiple circular sections also requires significant production space and equipment. Furthermore, the finished product is not easily transported. Summary of the Invention

[0004] This utility model provides a rocket storage tank shell, which can be assembled into a single shell by connecting multiple connecting shells, facilitating processing, production, and transportation. Moreover, during assembly, the adjacent connecting shells are vertically welded together, which is more convenient for processing and operation compared to the existing method of horizontal welding after vertical positioning when splicing rocket shells. Furthermore, the reinforcing ribs inside the connecting shells are easier to position and install, increasing the overall strength of the shell.

[0005] To solve the above-mentioned technical problems, this utility model provides an outer shell for a rocket storage tank, comprising: The outer casing includes multiple connecting casings; A connecting block is disposed between two adjacent connecting housings. The connecting block includes a first connecting block and a second connecting block. The first connecting block and the second connecting block are symmetrically arranged and are respectively connected to the two adjacent connecting housings. Reinforcing ribs are evenly distributed on the inner surface of the connecting housing.

[0006] As a preferred embodiment of the above technical solution, the number of connecting housings is set to eight.

[0007] As a preferred embodiment of the above technical solution, the thickness of the connecting housing is set to 1 mm, and the thickness of the connecting block is set to 3 mm.

[0008] As a preferred embodiment of the above technical solution, the first connecting block and the second connecting block are L-shaped and each includes an extension connecting plate and a limiting connecting plate. The connecting housing is disposed on the top surface of the extension connecting plate and on one side of the limiting connecting plate.

[0009] As a preferred embodiment of the above technical solution, the connecting housing and the connecting block are connected by laser welding, and two adjacent first connecting blocks and second connecting blocks are connected by argon arc welding.

[0010] As a preferred embodiment of the above technical solution, the reinforcing rib is U-shaped and there are multiple ribs. A positioning plate is provided on the outer side of the reinforcing rib near the connecting shell. The positioning plate is connected to the inner wall of the connecting shell by argon arc welding.

[0011] This utility model provides an outer shell for a rocket storage tank, which includes connecting shells, connecting blocks, and reinforcing ribs. The entire outer shell is produced by dividing it into multiple connecting shells and then welding them together to form a whole. During assembly, two adjacent connecting shells are fixedly welded to the first connecting block and the second connecting block, and then the first connecting block and the second connecting block are welded together to form a whole. The reinforcing ribs on the surface of the connecting shells are also easier to install and weld and lock. The entire rocket storage tank outer shell can be connected by multiple connecting shells to form a single outer shell, which is convenient for processing, production, and transportation. Moreover, the vertical welding between adjacent connecting shells during assembly is more convenient than the existing method of horizontal welding after vertical positioning when splicing rocket outer shells. Furthermore, the reinforcing ribs inside the connecting shells are easier to position and install, increasing the strength of the entire outer shell.
