Description

Technical Field

[0001] The utility model relates to the technical field of tank storage, in particular to a kerosene storage tank structure. Background Art

[0002] In the space rocket launch system, the kerosene storage tank provides stable kerosene for subsequent use. The existing kerosene storage tanks (such as Figure 1 The liquid inlet pipes (as shown) enter the storage tank in a single group and are arranged in the center of the equipment. The pipes in the axial direction of the cylinder do not cover the entire length of the cylinder, and the bubbling tube is not taken into consideration.

[0003] There are the following problems:

[0004] 1. The cryogenic liquid enters from the liquid inlet and exchanges with the kerosene stored in the equipment, which is arranged in the center.
