What role does the phase shift torque probe play?

The phase shift torque probe is an integral part of the propulsion system in various aircraft, including the T-6. Its primary function is to measure the torque applied to the propeller shaft, which in turn allows for accurate monitoring of propeller speed. By utilizing a phase shift technique, the probe can detect the differences in torque that correlate directly to the rotational speed of the propeller. This is essential for ensuring optimal engine performance and propeller efficiency, as it helps pilots maintain the correct settings during various phases of flight, such as takeoff, climb, and cruise.

The role of the phase shift torque probe is central to the effective operation of the propeller system, providing real-time data that can influence engine output and overall aircraft performance.
