表面张力贮箱的微重力实验验证--静平衡与重定位

新研制的表面张力贮箱保证在微重力或无重力环境下、在任何时候都能向系统提供不含气的推进剂，因而需要确定液体的空间分布以及在给定微重力加速度下的重定位过程，以便为贮箱的设计提供依据。为此，按照相似理论用缩比模型进行了一系列微重力落塔实验，然后根据测定的重定位时间计算出原型表面张力贮箱的重定位时间。

The Microgravity Drop Tower Verification of Surface Tension Tank--Static Equilibrium and Reset of Propellant

The newly developed surface tension tank will provide the propellant without gases for the thrusters at any time under any microgravity circumstance. Based on the similarity principle, a series of drop tower experiments with scale models and simulating medium had been taken to obtain the space distribution of propellant in the tank and the propellant reset process at certain levels of microgravity. Then the propellant reset time with scale models were measured. And finally the propellant reset time with full scale tank were calculated according to the measured reset time.
