Source sensing for ITT is generated by which thermocouples located between which components?

• A. Fourteen, Axial, Centrifugal compressors
• B. Eight, gas generator turbine, power turbine
• C. Fourteen, power turbine, RGB
• D. Eight, Axial, Centrifugal compressors

Answer: (B)

The correct choice highlights that the source sensing for the Integrated Tactical Training (ITT) is generated by eight thermocouples located between the gas generator turbine and the power turbine. This configuration is important because it allows the system to obtain accurate temperature readings that reflect the operational status and performance of the engine.

The positioning of these thermocouples between the gas generator turbine and the power turbine is crucial for monitoring the thermal conditions of the engines. Accurate temperature data is essential for ensuring efficiency, performance, and safety during operation. Understanding thermal dynamics in this area is key to maintaining optimal engine operations, as any variations can indicate potential issues that need to be addressed.

The number of thermocouples and their specific location are designed to optimize data collection for monitoring purposes, which is fundamental for effective engine management. This configuration supports the overall functionality and reliability of the thermal sensing system used in the TH-73A.
