上抛工作模式是一种有效的地基微重力实验技术．它能在基本上不增加落塔高度的情况下，成倍地增加微重力实验时间．本文将简要介绍在工程热物理所25米落塔设施上由实时过程控制技术和数控全速同步泛能换能技术组成的牵引式上抛技术的工作原理，基本组件，微重力状态下蜡烛火焰实验的初步结果，以及与NASA落塔和航天飞机实验结果的对比．
Throwing working mode is an effective ground-based microgravity experiment technique. It can multiply the microgravity experiment time without increasing the height of the tower. This article will briefly introduce the working principle, the basic components, the flame test of the flame in the microgravity state by the real-time process control technology and the NC full-speed simultaneous pan-energy conversion technology in the 25m drop tower facility of the Engineering Thermophysics The initial results, as well as the NASA drop tower and shuttle comparison of experimental results.
