| 摘要: |
| 在建立数学模型的基础上，通过采用遗传算法与一般确定性算法相结合的混合遗传算法开发了有效的适于大范围参数扰动和工况调整的非线性稳态特性仿真程序，并利用该程序对液氧／煤油补燃循环液体火箭发动机系统的大范围参数扰动和工况调整的稳态特性进行了仿真计算。计算结果表明，混合遗传算法是解决该类问题的有效方法，对类似发动机的研制与改进具有一定的指导意义。 |

| Abstract: |
| This paper focuses on the simulation of the nonlinear static characteristic for a propellant staged combustion cycle rocket engine of liquid oxygen/kerosene with it′s parameters widely ranged and the thrust and mixture ratio widely varied.On the basis of the development of mathematical model,and by using a combined genetic algorithm,a simulating code of effective nonlinear static characteristic was developed and desirable results were obtained. |
