- Abstract:
- The fault monitoring can improve safety and reliability of rocket engine effectively. A steady fault simulation model of high pressure staged combustion cycle LOX/kerosene rocket engine with high thrust is developed. The fault simulation analysis is conducted and the characteristic parameters of the engine fault monitoring are extracted. The selected fault modes which are possible to endanger the safe running of the engine are simulated and analyzed to obtain the order of engine parameters sensitive to the fault. Based on correlation analysis on relative deviations of measurement parameters, the correlation coefficients among the measurement parameters and measurement parameter sets with high correlation are obtained. The characteristic parameters for fault monitoring of the engine are extracted on the basis of sensitivity order and correlation of measurement parameters.
