液体推进剂的晃动特性对大型液体运载火箭以及战略弹道导弹的飞行稳定性有着很大的影响．为了使导弹和航天运载器具有良好的飞行稳定性，就必须对其内部液体推进剂的晃动加以抑制，避免使液体晃动与整体结构的固有振动发生耦合，防止结构的固有振动频率和液体晃动频率落入控制系统的频带之中．文中概述了近年来液体推进剂防晃研究方面所取得的进展
The sloshing characteristics of liquid propellants have a significant impact on the flight stability of large liquid-propellant rockets and strategic ballistic missiles. In order to make the missiles and space vehicles have good flight stability, the internal liquid propellant must be restrained from swaying to avoid the liquid sway coupling with the inherent structure of the overall structure to prevent the structure of the natural vibration frequency and the liquid shaking frequency Fall into the control system of the band. In this paper, the recent advances in the research on anti-sagging of liquid propellants are summarized
