| 摘要: |
| 在已有的液体火箭发动机稳态工况的非线性数学模型基础上, 计算分析了单干扰因素对液体火箭发动机参数的影响, 用非线性方法和小偏差方法对比分析了两个干扰因素分别和共同对发动机参数的影响。所得结论可用于泵压式燃气发生器循环的液体火箭发动机试验结果分析、可靠性及故障分析, 也揭示了此类发动机参数随各种干扰因素的变化规律。 |

| Abstract: |
| Based on the nonliear mathematical model for the steady state operation of a liquid rocket engine, the effects of each interfering factor on the parameters of liquid rocket engine are calculated. The comparative analysis is carried out for the effects of the interfering factors on the engine parameters by using both nonlinear method and method of small deviations. The results obtained can be used for the analysis of the pump-fed gas generator cycle liquid rocket engine test results，the reliability analysis and the fault analysis, and also for bringing to light the variation of the engine parameters with various interfering factors. |
