Problems solved by technology
At present, the commonly used local management surface tension storage tank separates the management cabin and the non-management cabin through the partition, because the partition is a large-area thin-walled structure, which is often damaged in the mechanical environment test, which affects the normal use of the storage tank. Thickening or reinforcement can improve its adaptability to the mechanical environment, but the effect is minimal, which greatly limits the scope of use of locally managed surface tension tanks

Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0027] In this embodiment, the anti-vibration liquid management inner core is an all-metal structure made of materials compatible with propellant grade I. In the manufacturing process, each mesh and the corresponding support plate structure are first assembled, that is, the second coarse mesh 14 is assembled with the third support plate 13 and the fourth support plate 15 to form a coarse mesh structure, and the fine mesh 11 and the second support plate are assembled. One pressing plate 10 and the ...

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...
