| Abstract: | The time series analysis method is applied to condition monitoring and fault diagnosis of aero engine.The trending values of monitoring parameters can be predicted by building and estimating auto regressive model.Then the time series analysis and the mode identification technique are combined and through determining classification function and conducting correlation analysis among the parameters,some typical faults of the engine can be identified. |
