摘　　要：微重力燃烧研究用落塔张孝谦，韦明罡（中国科学院工程热物理研究所北京１０００８０）关键词微重力，落塔，燃烧１引言微重力燃烧是燃烧学和空间科学交叉的一门新兴研究领域，具有重要的理论意义和应用背景。微重力状态下浮力、自然对流和沉积等因素对燃烧过程的影响十分...A microgravity drop tower has been built at the Institute of Engineering Thermophysics, Chinese Academy of Sciences. The drop tower consists of a building 7 meters square by 25 meters tall. Contained within the building is a drop area 22 meters long with a cross section of 4 by 5 meters. A 2-second period of microgravity can be obtained by allowing the experiment package to free fall from the top of the drop area. In order to minimize drag on the experiment package, it was enclosed in a drop shield designed with a high ratio of weight to frontal area and low drag coefficient. The microgravity level is estimated to be about 10-4g.The experiment package was suspended at the top of the drip area by a bomb-hook. No measurable disturbances were imparted to the package by the release system.The recovery system consists of four liquid dampers. The maximum deceleration rate is less than 25 g.
