Microgravity test system and test method for fluid transmission performance verification of plate tanks

Abstract

The invention provides a microgravity experiment system and an experiment method for verifying the fluid transmission performance of a plate type storage box. The microgravity experiment system for verifying the fluid transmission performance of the plate type storage box comprises a filling liquid storage box model, a filled liquid storage box model, a self-locking valve, a self-locking valve controller, an image acquisition device, a deflation valve, a nitrogen bottle, an inflation valve, an air passage control desk, a liquid injection valve, a simulation liquid tank, a pipeline three-way valve and other components, wherein a drop tower double-chamber experiment module is used for measuring and verifying the transmission action of fluid in the plate type storage box and controlling the fluid transmission time; a ground filling and control module fills nitrogen gas into the filling liquid storage box model before a drop tower experiment and fills propellant simulation liquid; and after the experiment starts, the ground filling and control module and the tower double-chamber experiment module are disconnected. The experiment system and the experiment method have the advantages that the structure is compact, the self-locking valve is adopted for automatic control, the time coordination and matching with microgravity is strong, the occupied area is small, the leak tightness of a loop is good, the models are replaced easily, camera shooting and observation are convenient, and the like.

Description

technical field [0001] The invention relates to the technical field of test and verification of fluid transmission performance of plate storage tanks under microgravity conditions, and can be popularized and applied to microgravity drop tower tests of various scaled models of plate storage tanks. Background technique [0002] During the "Eleventh Five-Year Plan" period, the design of the 28L plate-type surface tension storage tank for spacecraft on-orbit filling was completed, the prototype model was made, and the ground demonstration test of the propellant on-orbit filling process was carried out. This demonstration test can only verify the local performance of the plate surface tension tank, and cannot truly reflect its ability to manage, control and transmit fluids using surface tension in a space environment. Therefore, a large number of microgravity tests must be carried out to conduct an in-depth study of the fluid transport performance of the plate surface tension tan...
