SYSTEM AND DEVICE FOR MONITORING OF TURBOJET ENGINE VARIABLE GEOMETRY ACTUATOR SYSTEM FEEDBACK LOOP Russian patent published in 2016 - IPC G01M15/14 

FIELD: instrumentation.

SUBSTANCE: claimed process comprises the steps that follow. The monitoring parameters are evaluated proceeding from the data on feedback loop operation. The indicators are derived on the basis of the monitoring parameters. At least one signature is defined on the basis of at least magnitudes of the part of indicators. The degradation is detected and localised that influences the feedback loop subject to at least one defined signature.

EFFECT: higher efficiency of claimed process.
