What is the average temperature measured at the turbine discharge gases known as?

The average temperature measured at the turbine discharge gases is known as exhaust gas temperature (EGT). This temperature is critical for assessing the performance and efficiency of a gas turbine engine. Monitoring EGT helps determine if the engine is operating within its designed parameters and ensures that the thermal limits are not exceeded. High exhaust gas temperatures can indicate problems such as engine over-temperature conditions, which could lead to damage if not properly managed.

EGT is a vital measurement because it reflects the combustion efficiency and helps in diagnosing the health of the engine. Understanding the exhaust gas temperature allows technicians to make informed decisions regarding maintenance and operational adjustments.

Other temperature measurements, such as induced temperature, compressor discharge temperature, and intake air temperature, refer to different parts of the engine's operation and do not specifically represent the temperature of the gases exiting the turbine. Thus, they do not correctly identify the average temperature at the turbine discharge.
