摘　　要：大范围快速机动的在轨服务能力是航天器追求的目标之一,推进系统需要适应大加速度环境,具备在轨大填充比的加注能力,因而,贮箱在大加速度下的推进剂管理性能对飞行器的总体设计十分重要.本文采用数值模拟方法对板式表面张力贮箱的极限管理性能展开仿真研究,对贮箱内气液两相分布以及推进剂液面高度曲线进行分析,重点关注平行导流板在大加速度环境下的极限导流能力,通过设置不同平板板宽与间隙距离探究了结构参数对导流板导流特性的影响规律.结果表明,在10-2 g加速度下,适当增加平板板宽与减小导流板与贮箱壁之间的间隙距离均有利于提升平行导流板的导流效果,本文研究成果可为板式贮箱的优化设计提供理论参考.The future propulsion system needs to adapt to large acceleration environment and have the refueling ca-pacity with large filling volume.Therefore,it is very important for the overall design of aircraft to research the pro-pellant management characteristic of spacecraft tank at a large acceleration environment.In this paper,the limit management performance of a vane-type surface tension tank is studied by numerical methods.The gas-liquid distri-bution in the tank and the liquid level curves of the propellant are analyzed.The diversion capacity of parallel vanes under a large acceleration is calculated,and the influence of vane width and clearance distance on the diversion performance is studied.The numerical simulation results show that increasing the vane width and decreasing the clearance distance between the vane and tank shell can improve the diversion effect at 10-2 g acceleration.The re-search results of this paper can provide theoretical reference for the optimal design of vane-type surface tension tanks.
