The surface tension storage tank comprises a storage tank pressure-bearing shell, the storage tank pressure-bearing shell comprises an upper shell body, a column section and a lower shell body which are connected in sequence, the upper protruding middle partition is arranged in the storage tank pressure-bearing shell and divides the storage tank into an upper cabin and a lower cabin, an air nozzle is arranged at the top of the upper shell body, and an air outlet is formed in the top of the lower shell body. A liquid nozzle is arranged at the bottom of the lower shell, an air vent screen is arranged at the top of the middle partition, and a middle partition screen is arranged on the middle partition; during orbital transfer ignition, pressurized gas enters the upper cabin through the gas nozzle, a propellant in the upper cabin enters the lower cabin through the middle partition screen, liquid films are arranged in the middle partition screen and the gas outlet screen and can prevent the pressurized gas from entering the lower cabin before the propellant is used up, and gas in the lower cabin is discharged to the upper cabin through the gas outlet screen. The size of the middle partition required for partitioning the lower cabin with the same volume is smaller, the required structural mass is smaller, the mechanical environment adaptability of the upper convex middle partition is qualitatively improved, and the lower cabin can better adapt to vibration and impact in the rocket launching stage.
本发明提供了一种上凸中隔的表面张力贮箱,包括贮箱承压外壳,贮箱承压外壳包括依次连接的上壳体、柱段以及下壳体,贮箱承压外壳内部设置有上凸的中隔,中隔将贮箱划分为上舱与下舱,上壳体顶部设置有气嘴,下壳体的底部设置有液嘴,中隔的顶部设置有放气口筛网,中隔上设置有中隔筛网;变轨点火期间,增压气体通过气嘴进入上舱,上舱内的推进剂通过中隔筛网进入下舱,中隔筛网与放气口筛网中均设置液膜且能够阻止增压气体在推进剂耗尽前进入下舱,下舱内部的气体通过放气口筛网排放至上舱。本发明分隔相同容积的下舱所需中隔尺寸更小,所需的结构质量更小,且上凸中隔的力学环境适应性有质变的提升,更能适应火箭发射阶段的振动和冲击。
