Aero Thermodynamic

The main gas path components of a gas turbine engine, namely compressor and turbine, are inherently reliable. However its operation under hostile environments, such as varying conditions of load, temperature and speeds, and the cycle sensitivity to component degradation, results into engine breakdowns and performance deterioration. The deterioration of the gas path components cannot be prevented, and the engine performance always degrades increasingly with time. In an attempt to reduce the risk of such unwanted circumstances, commercial and military gas turbine users have engaged in some form of performance diagnostics. Gas turbine performance diagnostics is a fairly mature methodology to accurately detect, isolate and assess the changes in engine module performance, engine system malfunctions and instrumentation problems from knowledge of measured parameters taken along the engine’s gas path. Good estimates allow operators to make safe decisions, regarding the required maintenance actions.
