Which parameter is used to monitor the mechanical integrity of turbine engines?

Monitoring the exhaust gas temperature (EGT) is crucial for assessing the mechanical integrity of turbine engines. EGT provides insights into the combustion process and the efficiency of the engine. By measuring the temperature of the gases that exit the turbine, technicians can determine if the engine operates within the manufacturer's specified limits.

High EGT readings can indicate potential issues such as fuel-rich conditions, component malfunctions, or other anomalies that could affect performance and safety. Consistently monitoring EGT allows for proactive maintenance and helps to prevent engine damage by ensuring that the operating conditions remain optimal. This parameter serves as a vital indicator of the engine's overall health and performance, which is essential for safe operation.

While other parameters like oil temperature, fuel flow rate, and propeller RPM are important for their respective functions, they do not directly reflect the mechanical integrity of the turbine engine to the same degree as exhaust gas temperature does.
