Abstract	According to the principle of gas path electrostatic monitoring in aero-engine, it has established aero-engine gas path electrostatic monitoring system that can tolerate the high-temperature and high-speed airflow. There was developing the research about the mechanism of combustor carbon deposition and online electrostatic monitoring, the fault of combustor carbon deposition in aero engine. It was chose eight stages data from the large scale data of online electrostatic monitoring experiments and being based the time of checking the combustor in aero engine, comparably analyzing rms and Kurtosis being extracted from the data as features. In order to regain the accurate charge signal and discard certain trend item, it uses least mean square to finish the transforming process that is from electrostatic voltage to electrostatic charge. The changes of exhaust gas path electrostatic level illustrate by the features, including active level, positive event rate, and negative event rate extracted from the electrostatic charge signal. It responds for the fault of combustor carbon deposition in aero-engine as well as a slight ablation fault in testing process by the features of electrostatic voltage and charge, respectively, which is being to verify the monitoring results by the report of the engine dismantled. The research of online electrostatic monitoring the fault of combustor carbon deposition in this paper would be the foundation to achieve the application of the technology in aircraft.
