What is the maximum ITT at idle?

The maximum Intermediate Turbine Temperature (ITT) at idle is set at 750ºC. This specification is important because it serves as a safety limit to ensure the engine operates within its designed thermal thresholds. Exceeding this temperature could lead to adverse effects on engine materials and components, potentially compromising engine integrity and performance.

While other temperature limits may apply during different engine operating conditions, the idle ITT limit is specifically established for when the engine is at idle power settings. This ensures that when the engine is not under load, it remains within safe operating conditions. Thus, knowing and adhering to this maximum ITT at idle of 750ºC is critical for safe engine operation and longevity, as it helps prevent damage that could be caused by overheating during lower power settings.
