| 摘要: |
| 建立了液体火箭发动机的降阶非线性动态模型。针对已发生过的或极有可能发生的故障形式，进行了故障状态下动态特性模拟。仿真结果表明，所建模型较精确合理，并能实现实时随机仿真。 |

| Abstract: |
| resent a reduce-order nonlinear dynamic model of a liquid rocket engine.For everykind of fault types,dynamic simulation under condition of fault has been carried out.The resultsindicate that top model is reasonable and accurate,and real-time random simulation is achieved. |
| Key words: Liquid propellant rocket Engine Engine failure Fault analysis Real timesimulation |
