Abstract
A MODEL FOR PREDICTING THE PERFORMANCE IMPACT OF ENGINE DETERIORATION IS PROPOSED FOR FEASIBILITY EVALUATION. THIS MODEL WOULD ACCOUNT FOR ROTATING COMPONENT DETERIORATION SUCH AS INCREASED TIP CLEARANCES, SURFACE ROUGHNESS, LEADING EDGE BLUNTNESS AND VAN BOW AND TWIST. THE PROPOSED APPROACH USES A STAGE STACKING METHOD TO ALLOCATE LOSSES THROUGHOUT THE ENGINE WHICH ARE DEPENDENT ON OPERATING TIMES AND COMPONENT OPERATING PARAMETERS. THESE PARAMETERS ARE RELATED BACK TO ENGINE MISSION PROFILE SO THAT ALL OF THE NAVY MISSION PROFILES CAN BE ANALYZED USING THE FINAL MODEL. PREDICTED PERFORMANCE USING ENGINE SIMULATION DECKS WILL BE COMPARED WITH ACTUAL ENGINE TEST DATA TO VERIFY THE PERFORMANCE DETERIORATION MODEL.
