Abstract
For the engine modules performance deterioration and fault diagnostics, the modules operation contributions to engine parameters changes are analyzed to find the modules deterioration impact on parameters shifts to the EPR (Engine Pressure Ratio) based baselines optimally modeled by Quasi-Newton method. The modules performance assessment strategies for the engine type in this study are finally achieved through the WF-EGT, (N1-N2)-P25/P2, P3/P2-EGT linear correlation match and baseline deviation analysis and applied for verification.
