| Abstract: | The steady fault mathematical mode of large LH and LO rocket engine is built according to the process of engine. This mathematical mode contains seventy capable parameters and forty five disturbing parameters, in whide the Broyden method is adopted to find the solution. It has established the right way to simulate the fault. Finally we analyse the result of the simulation, at the same time, we compare it with the hot-test. They coincide well. |
