High Sensitive Methods for Health Monitoring of Compressor Blades and Fatigue Detection
Figure 9
Analysis of cause and effect [3]: (a) classic approach with influence of human and operational factors on fatigue problems of the blades; (b) holistic approach—a compressor blade crack is a “result” of the wrong level of energy flow inside the engine. The “causes” must be sought at the inlet or the combustion chamber thermodynamic parameters (flow dynamics path) or mechanical power transmission quality and flight loads (kinematic loads path).
