| 摘要: |
| 利用液体火箭发动机性能参数和内外干扰因素之间的一组随机非线性方程组，采用Ｍｏｎｔｅ－Ｃａｒｌｏ方法对发动机性能参数进行了模拟。通过计算获得了发动机性能参数的经验分布曲线，得到了它们的统计平均值和置信区间，与设计值相对照，符合得很好。这为火箭发动机的研制、生产、维修和可靠性评估等提供重要参考。 |

| Abstract: |
| In this paper,using non-linear equation groups indicating the relations between liquid rocket engine performances and interference factors,the engine performances are simulated by MonteCarlo method’ A empirical distribution curve and statistical average value and believalbe range are obtained.The calculation results are in good accordance with design.It is very useful for designing,pram dueing,preparing and reliability evaluating of engines. |
