POWER TURBINE (NP)
The final two turbine stages extract energy from the combustion gases to drive the
power turbine. At 100 % RPM the power turbine rotates at 30,908 RPM.
The power turbine support incorporates a thermocouple assembly, which senses the
temperature of the combustion gases as they exit the second stage gas producer rotor.
Four ALUMEL-CHROMEL probes generate a DC current directly proportional to the
temperature of the gas. The thermocouple harness averages the four voltages and
transmits the resulting signal to the ARINC-429 databus and IIDS.
