State Detection Method to the Aircraft Engine Based on the Time Domain Parameters Analysis Technology

The state detection method to the aircraft engine is very important to assure the aircraft's safety flight, which has developed a new technology to realize the fault diagnosis to the aircraft engine. The collection of aircraft engine vibration signal can be used to complete the aircraft engine state detection and the fault diagnosis. In this study, the pretreated aircraft engine's vibration signal was analyzed based on the time domain method, through the simulation, we can identify the aircraft engine's current state from the normal flight to the fault state. And the time domain parameters can accurately judge current aircraft engine state, which provide the research basis for the subsequent aircraft engine fault diagnosis type.
