Vibration-proof liquid management inner core

Abstract

The invention discloses a vibration-proof liquid management inner core. The vibration-proof liquid management inner core comprises a clapboard 1, an angle coarse particle collector 2, a coarse particle collector, a corner collector 3, and a bottom collector, wherein the coarse collector is connected between the clapboard 1 and the bottom collector, the angle coarse particle collector 2, the corner collector 3 are connected with the clapboard 1, the coarse particle collector comprises a force bearing barrel, a first thick mesh 7, a third supporting and pressing board 13, a second thick mesh 14, and a fourth supporting and pressing board 15, wherein the force bearing barrel comprises an adapter ring 5, an outer barrel 6, and an inner barrel 8, the bottom collector comprises a third collecting shell 9, a first supporting and pressing board 10, a thin mesh 11, and a second supporting and pressing board 12, wherein the bottom collecting shell is provided with a liquid outlet, and a thick collecting mesh structure is assembled by the third supporting and pressing board 13, the second thick mesh 14, and the fourth supporting and pressing board 15 from top to bottom. The vibration-proof liquid management inner core has the advantages of being simple in structure, and capable of effectively improving mechanical environmental adaptation of a storage tank, enhancing reliability of a system, and meanwhile meeting a mass flow requirement of the system.

Description

technical field

[0001] The invention relates to a propellant storage tank of an aerospace vehicle propulsion system, in particular to a liquid management inner core capable of realizing gas-liquid separation during the working process of a locally managed surface tension storage tank and capable of withstanding harsh mechanical environments. Background technique

[0002] With the development of space technology, low-thrust attitude and orbit control propulsion subsystems are widely used on satellites. The storage tank in this propulsion subsystem is mainly used to store propellant and pressurized gas, and to ensure that during the satellite flight phase, the specified flow of gas-free and pressure-disturbed propellant is supplied to the engine through the propellant management device. In recent years, propellant storage tanks have various forms such as piston storage tanks, capsule storage tanks, metal diaphragm storage tanks, metal membrane box storage tanks, and surface te...
