| Abstract: | Aiming at the bulky propellant tank with propellant management device (PMD), experiment research on liquid sloshing performance is carried out. The liquid sloshing tests in a tank without PMD are developed under different liquid filling ratios. Based on the equivalent mechanical model, the theoretical result of liquid sloshing is calculated. The results of tests and calculation are analyzed and compared. The results are consistent, both the reliability of test system and the validity of theoretical model are well verified. Then the liquid sloshing tests in the tank with PMD are developed under different liquid filling ratios, and the test results indicate that the structure of inner PMD significantly affects the performance of liquid sloshing in the tank. All the experiment research results provide an important reference and data support for designing and optimizing the attitude and orbit control system of rocket and spacecraft. |
