What term is used to describe the temperature measured aft of the turbine?

The term used to describe the temperature measured aft of the turbine is EGT, which stands for Exhaust Gas Temperature. EGT is a crucial parameter because it provides vital information about the performance and efficiency of the turbine engine. By measuring the temperature of the exhaust gases as they exit the turbine, engineers can assess how well the engine is operating and whether it is functioning within safe limits. Monitoring EGT is essential for engine management, as excessively high temperatures can indicate potential issues such as over-temperature conditions that could lead to engine damage or failure.

In contrast, ITT, which stands for Interstage Turbine Temperature, refers to the temperature between stages within the turbine itself, not at the exit. MAP, or manifold absolute pressure, measures the pressure of the intake manifold, which is unrelated to temperature. RPM refers to the revolutions per minute of the engine or its components and also does not pertain to temperature measurement.
