【摘要】 介绍了国家微重力实验室（NMLC）落塔自由落体实验装置。与国外同类装置相比,该装置的特点是采用双舱结构,内外舱间抽真空的方案,并利用同步电机制动特性及弹性机构进行落舱的回收。这些措施可以更便捷,更经济地进行微重力燃烧实验。对调试过程中获得的结果进行了初步分析,结果表明该装置达到了预期的设计。更多还原

【Abstract】 The free fall facility of the drop tower of NMLC is introduced. Compared with the similiar facility abroad, it’s characters are double capsule structure, the space between the two capsules is evacuated and the recovery system utilizes the break character of synchronous motor and elastic cord. These techniques make the test procedure more easy and more economic. The data gained during the setup stage is analyzed. The result shows that the design goal is achieved.更多还原
