On-board engine control computers contain logic that monitors for anomalous engine operation in real-time. Today, performance trend monitoring and gas path fault diagnostic functions are performed by a combination of on-board and off-board strategies. Trend monitoring is the process of monitoring the gradual performance change that an aircraft engine will naturally incur over time due to turbomachinery deterioration, while gas path diagnostics is the process of detecting and isolating the occurrence of any faults impacting engine flow-path performance.
Some visible benefits have been gained so far through the prototype system installed at the Chinshan nuclear power stationĪn Integrated Architecture for On-Board Aircraft Engine Performance Trend Monitoring and Gas Path Fault DiagnosticsĪircraft engine performance trend monitoring and gas path fault diagnostics are closely related technologies that assist operators in managing the health of their gas turbine engine assets. They are Test Data Processing Subsystem (TDPS), On-line Monitoring and Analysis Subsystem (OMAS), and Thermal Performance Diagnostics Expert System (TPDES). Three subsystems were generated to support the whole system framework. The system can carry out turbine performance monitoring and analysis during normal operation, and yield diagnostic results of component degradation after finding out the missing generation problems. It was the product of the ChinShan plant performance Monitoring, Analysis and Diagnostics Expert System (CS-MADES) project sponsored by Taiwan Power Company (TPC). International Nuclear Information System (INIS)Īn on-line computerized system for thermal performance monitoring and diagnostics has been developed at the Institute of Nuclear Energy Research (INER).
