| Abstract: | Considering the actual management of the aero-engine fleet in civil aviation,using the HOLT double parameters exponential smoothing method,the monitoring model of the differences between the performance parameters of the symmetrical aero-engines is built based on airborne QAR data,and the algorithm is given to realize the aero-engine monitoring.The results of numerical examples indicate that the proposed model and algorithm can effectively recognize condition,and predict faults of aero-engine,make the engine troubleshooting port in advance.Moreover,the monitoring method is simple and easy to implement. |
