Risk Assessment of Aero Engine Failure based on Monte Carlo Simulation

The risk simulation model of aero engine failure has been developed based on Monte Carlo method. The model has been established to predict and evaluate the failure risk of aero engine during operational phase to ensure the reliability and security. Risk assessment of a particular engine was conducted on the basis of the failure events hazard level and the corresponding risk guidelines. During the assessment, three reasonable corrective actions have been developed and estimated to analyze the effect of different maintenance methods and inspectional intervals on the failure risk factor.
