Changlong Aviation's invention patent "A method and device for monitoring the performance of aircraft integral drive generators" was recently approved. This is Changlong Aviation's first independent research and development, application and national invention patent authorization.

This invention patent provides a method for the civil aviation industry to use aircraft static and dynamic feature data, real-time sensor data, historical time series data and other heterogeneous data, combined with discrete feature values of parameters, to determine the performance trend of key parts of the aircraft. A gap in predictive performance monitoring technology for integrated drive generators (IDG). Collect the operating parameter data of the target aircraft through sensors. After data transmission and decoding are completed, Grubbs criterion is applied to remove "abnormal data". For multiple sensors, IDG performance monitoring and fault trees based on big data analysis are established to extract important parameters. And perform algorithmic calculations to obtain the performance characteristic values of multiple complex dynamic scenes, and then through the aggregation and separation of multiple performance characteristic values, predict the IDG performance degradation trend and remaining life in advance.

This invention patent solves the problem of monitoring the performance trend of important parts of aircraft such as IDG in actual production. This method can reduce the IDG failure rate and the number of ultra-economic maintenance, prolong the service life, and improve the safety, reliability and maintenance quality of the aircraft, and reduce costs. Efficiency enhancement provides technical support and drives the industry's development and progress in predictive maintenance of aircraft health.
