- 摘要:
- 针对凝胶推进剂压力损失的计算方法与常规推进剂存在很大差异．结合对非牛 顿流体的理论分析．得出了凝胶推进剂在管路中的流动特性主要取决于其自身。对凝胶N：仉 及凝胶UDMH液流试验的压力一流量数据，分别采用指数方程、多项式方程和直线方程三种 方法进行曲线拟和、对比分析，反映了凝胶推进剂的非牛顿流体特性，对系统组建提出了一 些建议。明确了凝胶试验系统试前应采用真实介质进行冷调，并为系统调试数据提供了可行 的拟合方法。
- Abstract:
- Throush the theoretical analysis of non—Newtonian fluid．it is concluded that tIle flow characteristic of gelled propellant in the pipeline mainly depending on its own characteristics．There exists distinct difference between the calculation method of the pressure loss of gelled propellant and that of liquid propellant．This paper adopts the Allometric，polynomial and linear equations to perform the curve fitting and comparative analysis on the pressure versus flux test data of gelled N204 and UDMH，which reflects the non-Newtonian fluid characteristic of gelled propellant．Some suggestions to establish a system have been put forward．It is proposed that real medium should be used to carry out the cold conditioning prior to the test of gel test system．The feasible fitting method is also provided for system adjustment data in this paper．
