AI Technical Summary

Problems solved by technology

This type of collector uses a large number of stainless steel screens, while other materials are titanium alloys, which cannot avoid the problem of incompatibility of welding materials, which leads to poor structural strength and low reliability. The structural form is prone to gas blockage during filling, so the filling speed is slow, and it is not conducive to repeated filling
In addition, the structure of this type of collector is not easy to connect with the accumulator, and the adaptability is poor

Embodiment Construction

[0023] Such as image 3 As shown, the plate-type propellant management device collector includes four upper collectors 12, four lower collectors 14, and collector connecting pipes 13; the upper and lower collectors are designed as a group, and the upper and lower collectors There are four groups in total connected by the collector connecting pipe 13. The upper and lower collectors are arranged at an angle of staggered by 45° to cooperate with the liquid accumulator 15 and the deflector 16, so that at least There is a collector submerged in the liquid that delivers air-free liquid to the tank outlet. Place the upper collector 12 on the outer cone of the liquid accumulator 15 and close to the top, in the same axial plane as the deflector 16, so that at least one collector can be submerged in the north-south position and the east-west position. in liquid. The lower collector 14 is placed in the gap between the deflectors 16 to ensure that the lower collector is fully submerged...

Abstract

The invention relates to a collector of a plate-type propellant management device, which comprises an upper collector (12), a lower collector (14) and a collector connecting pipe (13), each upper collector (12) and each lower collector (14) are combined as a group, the total number of the groups is four, and each upper collector and the lower collector are connected by the collector connecting pipe (13); each upper collector and each lower collector are arranged by forming a 45 degree angle. The collector of the plate-type propellant management device has the advantages of high reliability, simple structure, high strength and strong adaptability.

Description

technical field [0001] The invention relates to a collector of a propellant management device, especially suitable for propellant management in space microgravity environment. Background technique [0002] Surface tension tanks are widely used in various spacecraft such as satellites, spaceships, space stations, and launch vehicles due to their high reliability and long life in a weightless environment. The core technology of the surface tension tank is its internal propellant management device (referred to as PMD). The plate type propellant management device belongs to a new generation of reliable and advanced management devices. The goal of collector design is to design one of the important components of plate PMD with reliable performance, simple structure, high structural strength and strong adaptability. [0003] At present, the PMDs of the surface tension storage tanks used in my country's satellites are all mesh-type, and a large number of screens are used as capill...
