Compressor Discharge Temperature (CDT) Probe – How it works in Aircraft?

For the uninitiated, the gas turbine you see in the single and twin-engine aircraft is an internal combustion engine that uses air to drive the engine and propeller, which in turn, propels the airplane. It achieves this with the help of heat energy from fuel that it converts to mechanical energy via the pistons. Here’s…

Usage and Significance of CDT Probe in Aircraft

The Compressor Discharge Temperature (CDT) probe (not to be confused with Conductivity, Temperature, Depth probe used in ships and also called CDT probe), is installed in the engine compartment just after the inter-cooler. The probe is installed with a #40 stainless steel clamp. A large clamp is supplied to fit around the air-port leaving the…
