Research on Engine Performance Deterioration Index Based on Statistical Analysis
Tan We · Aeronautical Computing Technique · 2015
The sensitivity of engine monitored parameter to component performance parameter was analyzed by engine component model,index that fully represents performance deterioration was selected according to PRESS principle,change of engine performance was tracked by establishing statistics of performance deterioration index residual sequence. The Results indicate: index residual sequence can confirm key point of performance change,monitor engine performance,provide decision to realizing passive maintenance.
