Aeroengine Condition Monitoring System Based on Non-Interference Discrete-Phase Compressor Blade Vibration Measuring Method

Abstract : Described method is of great importance for flight safety and may be recommended as a completion of the existing systems of diagnostic of turbine engines. 2. By using the discrete non-contact method of measuring blades vibration and numerical analysis of blade vibration spectrum it is possible to conduct complex, monitoring of technical state of major engine components like: - compressor blades - fuel system - bearing system.
