摘　　要：板式表面张力贮箱的PMD通常包括导流板与出口附近的蓄液器,导流板是影响板式贮箱性能的关键因素之一,由于地面没有失重环境无法直接进行导流板的工作原理地面验证。为了确认导流板的可用性,通过理论分析建立了导流板液体传输能力的计算方法,通过中性浮力试验对导流板的液体收集能力进行了试验验证。经过多次试验的试验结果与理论计算结果的对比分析,得到了一种可应用于工程设计的计算方法,利用该方法编程形成了一套计算软件,可指导板式表面张力贮箱内导流板的设计。Vane type surface tension tank’s PMD usually include vanes at wall and liquid reservoir at outlet.Vane is a critical component on liquid collecting capacity,but this cannot be verificated at the ground condition because without microgravity condition.In order to verify the usability of vans,theoretical calculation method for liquid transportation ability of vane was built.Then neutral buoyancy test was conducted to validate liquid collection capacity of vane.The experimental verification result was contrasted with theoretical calculation result,and a calculation method sutiable for engineering design was obtained.Finally a vane computing software was formed to direct the vanes design in vane type surface tension tank.
