介绍了美国宇航局刘易斯研究中心在其所属低温部件实验室和Plumbrook实验站的K基地进行的“无放空加注”实验研究的实验设备、三种基本输送方式、实验过程及结果。研究表明,空间低重力环境下的“无放空加注”是低温液体的一种有前途的输送方式。
This article introduces the experimental equipment of “emptying” experiment conducted by Lewis Research Center of NASA at the K base of its low temperature component laboratory and Plumbrook experimental station, and three basic transportation methods, experimental procedures and results. Studies have shown that “no-empty filling” in low-gravity space environment is a promising transportation method for cryogenic liquids.
