VIBRATION DIAGNOSTIC METHOD OF GAS TURBINE ENGINE Russian patent published in 2019 - IPC G01M15/14 

FIELD: machine building.

SUBSTANCE: invention relates to monitoring of technical state of gas turbine engines (GTE), namely, to gas turbine engine vibrodiagnosis. Disclosed method can be used for monitoring the vibration state of aircraft GTE both on ground information processing devices and in onboard engine control systems, and can also be used for vibration diagnostics of engines used in power engineering and for gas transportation. Substance of the invention consists in application of nonlinear dynamics method for vibration signal processing with subsequent comparison of the suggested vibrosignal structure index with its values in faulty and faulty conditions of gas turbine engine.

EFFECT: disclosed method for vibration diagnostics of gas turbine engine allows estimating state of engine bearing bearings by evolution of vibration level from standard sensor.
