Plate-type surface tension storage tank

Abstract

The invention provides a plate-type surface tension storage tank. The plate-type surface tension storage tank comprises a guide plate assembly, a lower management cabin assembly and a liquid pipe, theguide plate assembly comprises an upper shell, a connecting ring and a flow guide plate, the flow guide plate is connected into grooves of the upper shell and the connecting ring, and the upper shellis provided with a gas-liquid opening; the lower management cabin assembly comprises a lower shell, blades, a pressing plate and a barrel collecting assembly; the blades are respectively connected with the barrel collecting assembly, the pressing plate and the lower shell, and the barrel collecting assembly is connected to the lower shell; wherein the upper shell is connected with the lower shell; one end of the liquid pipe is connected with the gas-liquid port, and the other end of the liquid pipe is connected with the cylinder collecting assembly. The plate-type surface tension storage tankhas the advantages of being more suitable for various liquid propellants, more sufficient in ground performance verification and the like, and can serve as a liquid propellant management plate type surface tension storage tank in aerospace products such as satellites.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a plate-type surface tension storage tank, and more specifically to a plate-type surface tension storage tank, which can be used as a liquid propellant management device in aerospace fields such as satellites. Background technique [0002] The plate type surface tension storage tank has the advantages of light weight and strong resistance to mechanical environment. However, the plate surface tension storage tanks used in the existing aerospace field, firstly, the material of the storage tanks is mainly titanium alloy, which has good compatibility with conventional toxic propellants widely used at present, but it is not compatible with some new non-toxic propellants. The compatibility of the propellants is poor, and they cannot be used together; the second is that the discharge performance of the storage tank cannot be verified in the ground-1 gravity environment because there ...

Problems solved by technology

However, the plate surface tension storage tanks used in the existing aerospace field, firstly, the material of the storage tanks is mainly titanium alloy, which has good compatibility with conventional toxic propellants widely used at present, but it is not compatible with some new non-toxic propellants. The compatibility of the propellants is poor, and they cannot be used together; the second is that the discharge performance of the storage tank cannot be verified in the ground-1 gravity environment due to the lack of a connection channel structure of the mesh surface tension storage tank.

In short, the existing plate-type surface tension storage tanks have disadvantages such as a small range of compatibility with the working medium, and the inability to directly test and verify the discharge performance under the ground-1g gravity environment.
