what is ITT?

[Obi-Wan]

I know that ITT is usually taken from the discharge of the HPT. But Ive had a total brain fart and cannot remember what the letters in ITT stand for.
Something Turbine temp???

ITT

Internal Turbine Temp. whether an actual number or a synthic number.

 

[Obi-Wan]

You made my day. For some reason I could not remember at all.
thanks.

Between LPT & HPT

I think I've heard it referred to as intra-stage, or inter-stage temp, but internal makes sense, too. In the CF34-3A1, the probes (10) are between the low pressure turbine and high pressure turbine.

ITT

On the Pratt PT6 it stands for interstage turbine temperature. It's a measure of the engine gas temp between the compressor turbine and the power turbine.

 

[RJones]

ITT (Interstage Turbine Temperature) Temperature of hot gases at some intermediate position between multiple turbine wheels.

Straight from the Garrett manual.
