Embodiment 1

[0054] This embodiment provides a specific implementation of the energy dissipator, such as Figure 1 to Figure 5 As shown, it includes a connection part 1 and a main structure 2 . The connection part 1 is suitable for connecting with the pressurization port provided on the side wall of the tank, and the first channel 3 suitable for the passage of pressurized gas is arranged in the connection part 1; the main structure 2 and the connection part 1 The main structure 2 is provided with a second channel 4 communicating with the first channel 3, the main structure 2 extends in the circumferential direction of the storage tank, and at least one end of the main structure 2 is provided with sieve hole.

[0055] The cross-sectional area of ​​the second passage 4 is larger than that of the first passage 3, which can increase the flow area of ​​the pressurized gas and reduce its velocity.

[0056] Such as figure 1 As shown, the main structure 2 is arc-shaped, which is suitable for th...

Abstract

The invention provides an energy dissipater. The energy dissipater comprises a connecting part and a main body structure, wherein the connecting part is suitable for being connected with a pressurizing opening formed in the side wall of a storage tank, and a first channel suitable for pressurized gas to pass through is formed in the connecting part; and the main body structure is connected with the connecting part, a second channel communicating with the first channel is formed in the main body structure, the main body structure extends in the circumferential direction of the storage tank, andat least one end of the main body structure is provided with sieve holes. The sieve holes are formed according to the small hole group silencing principle, energy is reduced, noise is reduced, and the flow speed is uniform; and due to the fact that the main body structure extends in the circumferential direction of the storage tank, and the gas outlet direction is perpendicular to the axial direction of the storage tank, the liquid level in the storage tank is stable, impact on the liquid level is avoided, pressure above the liquid level is uniform, and the shape of the main body structure issuitable for installation of a lower tank of the lower convex common-bottom storage tank.

Description

technical field [0001] The invention relates to the technical field of storage tank propellant management components, in particular to an energy dissipator. Background technique [0002] The energy dissipator is one of the propellant management components in the propellant tank. Its main function is to maintain the stability of the liquid level and the pressure of the tank to ensure the normal operation of the propellant in the engine system. [0003] The propellant of the liquid rocket is stored in the fuel storage tank, and is introduced into the combustion chamber by the bottom delivery pipe to mix and react, and generate energy to make the rocket itself obtain upward thrust. However, as the fuel is consumed, the liquid level in the storage tank gradually drops, and the fuel liquid As the air pillow above the surface increases, the internal pressure will become lower and lower. In order to ensure the continuity and stability of the fuel supply, it is necessary to inject h...
