摘要:

用修正迭代法和Newton－Raphson法，对表面张力贮箱的液体管理装置进行了网络分析计算和技术分析，确定了表面张力贮箱满足微重力或低重力下无泡排液条件时，液体管理装置中的收集器筛网尺寸、气泡陷井通气管尺寸，比较了不同介质的蓄流能力。

Abstract:

Describes to calculate the retention capability of propellant management device byusing pressure network analytics. Iteration and Newton-Raphson methods are applied to rectify thedevice. To acquire ground test qualification of propellant tank, it is important to reduce the frictionalresistance loss of management device to the utmost. So sophisticated network of pipes is adopted. Ananalytical model was developed to simplify, Based on the calculative results, a rational structure insidea propellant tank can be designed to ensure gas-free propellant delivery.
