an analysis tool 50 the analysis tool 50 may be an expert analysis tool that may analyze the results of the module trends these trends and or combinations of trends may be utilized by the analysis tool 50 to determine the health of the modules of the turbine system 10 as well as the type of failures occurring in the turbine system 10 for example a hp compressor module may lose efficiency over time based on a comparison of the trends of the hp compressor module with for example the efficiency for a hp compressor module from the engine model 48 the analysis tool 50 may determine that the efficiency of the hp compressor 22 is being impacted by dirty blades accordingly a message may be transmitted to the workstation 52 indicating that the hp compressor 22 should be cleaned in one embodiment the analysis tool 50 may be one or more look up charts that may be part of a computer program stored on a machine readable medium such as a disk drive or memory alternatively the analysis tool 50 may be part of an integrated circuit the analysis tool 50 may be programmed to include alarms repair notices and or notices for sensor or module failure these different results programmed into the analysis tool 50 may represent programmed responses for predicted failure types of the turbine system 10 based on differences between the results transmitted from the health estimator 44 and the engine model 48 the analysis tool 50 may also be updated during the life of the turbine system 10 to adjust the analysis tool 50 prediction algorithm according to the tendencies of the turbine system 10 as described.
