Microgravity experimental system for component performance verification of plate type propellant management device

Abstract

A microgravity experimental system for the component performance verification of a plate type propellant management device comprises an experimental system baseplate, height adjustable experimental support assemblies, image collecting systems, illuminating systems, and the like, and is provided with two experimental models simultaneously, namely, two sets of the height adjustable experimental support assemblies, the image collecting systems, the illuminating systems and the like are all arranged on the experimental system baseplate symmetrically. The experimental system has the advantages that the structure is simple and compact, the efficiency is high, the adjustability is strong, the replacement of the models is easy, the image collection is convenient, the system can be realized easily and the like. According to the invention, a microgravity experiment of experimental models of plate type PMD components can be performed, the fluid transmission characteristic and the fluid management capability of all the plate type PMD component models can be obtained, and the PMD performance can be subjected to verification.

Description

technical field [0001] The invention relates to the technical field of test and verification of fluid transmission performance and management performance of a plate-type propellant management device (PMD) under microgravity conditions, and can be popularized and applied to microgravity tests of scaled models of various plate-type PMD components. Background technique [0002] With the rapid development of large-scale truss platform satellites in the world, propellant tanks using plate PMDs have become the mainstream in the world. Since the end of the "Eleventh Five-Year Plan", the development of large-capacity plate-type PMD propellant storage tanks has been carried out. The plate-type PMD prototype has been developed, and the ground demonstration test of the plate-type PMD fluid transmission performance and management performance has been carried out. This demonstration test can only verify the local performance of the plate-type PMD, and cannot truly reflect its ability to ...

Problems solved by technology

[0003] At the same time, since the development of plate-type PMD propellant storage tanks and related test verification technologies involve national security, countries that have mastered this technology often impose technical blockades. The information that can be provided by foreign countries is not comprehensive and can only serve as a reference. None of the relevant articles mentioned the detailed test system design. The mechanism research of the plate tank must build a test system by itself to carry out a large number of microgravity tests and obtain sufficient first-hand information. It is impossible for these basic information to be obtained from obtained from foreign literature

[0004] In summary, a microgravity test system for performance verification of plate-type PMD components is the result of exploration and summary during the development of large-capacity plate-type PMD propellant tanks. The entire test system is brand new, and there are no relevant documents and materials in China. It can be used as a reference, and foreign countries rarely disclose similar test systems
