Method for verifying guide plate performance microgravity tests in plate type propellant management device

Abstract

The invention discloses a method for verifying guide plate performance microgravity tests in a plate type propellant management device. Guide plate scaling model components different in section shape are test objects. According to the testing method, a method for realizing microgravity tests of the guide plate scaling model components different in section shape and different testing condition replacing strategies are mainly designed, and test preparation, test procedures, camera shooting observing methods, test anti-interference strategies and the like are stipulated. The testing method is reasonable in design, strong in operability, and capable of realizing all tests of microgravity of the guide plate scaling model components and recording the whole fluid conveying process in a shooting mode, and brings convenience to analysis of subsequent test results and guide plate optimized designs. According to the testing method, fluid management and conveying characteristics of guide plate models can be acquired, and performance of the guide plates can be verified.

Description

technical field [0001] The invention relates to a method for testing and verifying the fluid transmission performance of deflectors under microgravity conditions, which is a part of a plate-type propellant management device (PDM), and can be popularized and applied to microgravity tests of various deflector scaled models . 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 manage, control and tr...

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 related articles mentions the detailed test system design. For the mechanism research of plate-type PMD components, it is necessary to build a test system by itself, carry out a large number of microgravity tests, summarize the verification methods of microgravity tests, and obtain sufficient first-hand information. Basic information is impossible to obtain from foreign literature

[0004] To sum up, a microgravity test verification method for the performance of a plate-type PMD-deflector is the result of exploration and summary during the development of a large-capacity plate-type PMD propellant storage tank. The entire test method is brand new. There are no relevant literature and materials to learn from, and foreign countries rarely disclose similar test systems
