POWER TURBINE INLET TEMPERATURE INDICATING SYSTEM
This system consists of a dual-junction thermocouple cable and six thermocouples. Two
connectors are provided in the thermocouple cable illustrated in figure 8.11. One is for connecting to an
averaging indicator and the other is for individual checking of the thermocouples. This system functions
the same as the exhaust gas temperature-measuring system described in chapter 2.

The Pratt and Whitney T73-P-1 and the T73-P-700 are used to power the CH-54 flying crane
helicopter. This engine is a straight-flow, axial-compressor, free-turbine powerplant. The axial flow
