Problems solved by technology

[0003] Existing liquid accumulators belong to the type of radially placed blades. This type of liquid accumulator has some disadvantages: low structural strength, complex installation process, small liquid storage capacity, slightly poor ability to withstand the mechanical environment, poor adaptability, and poor adaptability to satellites. The control ability is high, the reliability is not high, and it is not easy to connect with the deflector

Embodiment Construction

[0031] Such as Figure 1~4 As shown, the accumulator of the plate-type propellant management device includes the following components: accumulator inner cone 1, accumulator outer cone 4, accumulator base 5, air guide tube 3, two air guide tube fixing blocks 2, two Liquid accumulator mesh support pressure plate 6, liquid accumulator mesh 7. The inner cone 1 of the accumulator is electron beam welded to the outer cone 4 of the accumulator; the outer cone 4 of the accumulator is electron beam welded to the base 5 of the accumulator.

[0032] The accumulator adopts two complete conical structures inside and outside, that is, the conical structure composed of the inner cone 1 of the accumulator and the outer cone 4 of the accumulator. The angled area between the outer cones of the accumulator and the angled area between the outer cone 4 of the accumulator and the inner wall surface 8 of the tank shell are used to store sufficient propellant, and the air guide tube is used The gas...

Abstract

Disclosed is a liquid storage device of a plate-type propellant management apparatus. The liquid storage device contains a liquid storage inner cone (1), a liquid storage external cone (4), a liquid storage pedestal (5), a gas-guide tube (3), a liquid storage screen support and pressure plate (6) and a liquid storage device screen (7). The liquid storage inner cone (1) is welded with the liquid storage external cone (4). The liquid storage external cone (4) is welded with the liquid storage pedestal (5). By the utilization of surface tension, the propellant is stored in an included angle area between the liquid storage inner cone (1) and the liquid storage external cone (4) and an included angle area between the liquid storage external cone (4) and a tank shell internal face (8). The gas in the liquid storage device is discharged by the use of the gas-guide tube (3). The liquid storage pedestal (5) is cylindrical. The liquid storage screen support and pressure plate (6) and the liquid storage device screen (7) are installed on an internal cylinder of the liquid storage pedestal (5). According to the invention, a simple and reliable structure is used to store sufficient liquids so as to realize overall management of liquids by plate-type PMD.

Description

technical field [0001] The invention relates to a liquid accumulator of a propellant management device, which is 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 accumulator design is to design one of the core components of plate PMD with reliable performance, light weight and simple structure. [0003] The existing liquid accumulator belongs to the radiation-placed vane type liquid accumulator, which has some disadvantages: low structural strength, complicated installation p...
