大加速度环境下板式贮箱内极限导流特性
Limit Diversion Characteristics of a Vane-type Tank under High Acceleration Conditions
摘要
Abstract
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.关键词
