| 摘 要： | 基于系统分解方式,建立凝胶推进剂火箭发动机工作过程的数学模型,并采用液流试验数据对其进行修正.由于同时考虑液体的惯性、粘性和压缩性,所以本文建立的常微分方程组能反映管道中推进剂流动的分布特性.通过对发动机工作过程仿真分析,为发动机型号研制提供参照和依据.

| Abstract: | This paper established the mathematical models of the whole operation process of gelled propellant rocket engine based on system disassembly.In order to obtain higher precision in simulation calculation,we made use of the propellant flowing experiment results to adjust the parameter values of some important characteristics.The established ordinary differential equation set can synchronously take the inertia,viscosity and compressibility of liquid into account,so it can generally reflect the distributed characteristics of the operation process in the supplying system.Based on the simulation data,the dynamic characteristics of the engine were discussed.The results can provide some refernces for designing the gelled propellant rocket engine in the future. |
