摘要
为验证板式贮箱蓄液器的蓄液性能,搭建了蓄液器模型试验系统,针对蓄液器模型的蓄液性能和流体传输行为进行微重力落塔试验研究,得到微重力环境下蓄液器的流体蓄留和传输规律.试验结果表明,相对于楔形蓄液器,双圆锥形蓄液器具有更好的蓄液能力,对于双圆锥形蓄液器,承受侧向加速度时仍具有良好的蓄液能力,合理设计蓄液器结构可有效地蓄留液体并控制液体传输速度.该试验成果不仅为新型板式流体管理部件设计优化提供参考,同时也为空间环境下流体控制提供了一种新方法.
In order to test and verify storage performance of vane type surface tension tank （STT）, a model testing system is established and the microgravity drop tower tests are conducted based on experimental study of fluid storage and transportation behavior of propellant refillable reservoir （PRR）. The rules of fluid storage and transportation of PRR in microgravity environment are obtained. The test results show that double-cone PRR have good liquid storage capacity more than cuniform PRR, and the double-cone PRR exhibits good liquid storage capacity with lateral acceleration. A rational design of PRR can effectively store liquid and control the velocity of liquid transportation. The test results offer a guideline for the optimization of new-style vane-type PMD, and also provide a new method for fluid control in space environment.
