中文摘要：

从某型民航客机发动机机队管理的实际出发,利用HOLT双参数指数平滑方法,建立基于机载QAR数据的对称发动机性能参数的差异监控模型,并给出实现对称发动机差异监控的算法。算例分析表明模型和算法能有效地识别发动机运行状态,并能预测发动机故障征兆,使发动机排故端口提前,且方法简单易于实现。

英文摘要：

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.
