What does ITT stand for in the context of engine performance?

In the context of engine performance, ITT stands for Internal Turbine Temperature. This measurement is crucial because it indicates the temperature of the gases exiting the combustion section and entering the turbine section of the engine. ITT is a critical parameter that engineers and pilots monitor during operation, as it helps ensure that the engine is functioning within safe thermal limits. High temperatures can lead to reduced engine efficiency and increased wear or damage, making it essential for maintaining performance and reliability. Understanding ITT is key for assessing engine performance and for making informed decisions regarding engine operation and safety.
