High-rigidity propellant management device for large surface tension storage box

Abstract

A high-rigidity propellant management device for a large surface tension storage box comprises a middle bottom, a liquid channel, a gas discharge channel, small collectors of the middle bottom, a gas discharge cup, a large collector of the middle bottom and a bubble trap, wherein one end of an angular collector of the liquid channel is connected with the middle bottom; the other section of the angular collector of the liquid channel is connected with the bubble trap; the bubble trap is fixed at an outlet of the storage box; the large collector of the middle bottom is positioned in the middle of the middle bottom; the small collectors of the middle bottom are distributed at the periphery of the large collector of the middle bottom; the gas discharge channel is placed on the upper portion of the middle bottom; one end of the gas discharge channel is welded to the edge of the middle bottom; and the other end of the gas discharge channel is suspended. The high-rigidity propellant management device of the large surface tension storage box overcomes the technical shortcomings of the existing small-capacity net-type storage box, can carry a large amount of propellant, and is high in reliability; the adaptive capacity of a large satellite is strengthened; propellant which does not clamp gas and meets the requirement on flow can be provided for an engine or a thruster in a microgravity environment; and the high-rigidity propellant management device is used for managing the propellant in the microgravity environment of space.

Description

technical field [0001] The invention relates to a high-rigidity propellant management device for a large-scale surface tension storage tank, which can provide an engine or thruster with air-free propellant meeting flow requirements in a microgravity environment. Background technique [0002] The propellant tank is one of the most important parts of the spacecraft. Its function is to store and manage the propellant. Under the specified flow and acceleration conditions, it provides the engine or thruster with air-free propellant. Its core component is the propellant management device (PMD). The surface tension storage tank is the most widely used propellant storage tank in the world at present, and it is divided into two types: mesh type and plate type. The existing surface tension storage tanks in our country are all mesh type, which use the surface tension of the liquid to collect propellant through the screen, and at the same time prevent the gas from entering the pipeline...
