Abstract
A turbine engine includes a plurality of fan blades configured to rotate about a longitudinal centerline axis of the turbine engine, a pitch actuator configured to control a pitch angle of each of the plurality of fan blades, a sensor assembly configured to detect a holding torque of the plurality of fan blades, and a controller configured to monitor propeller whirl in the plurality of fan blades by detecting the holding torque. The sensor assembly includes a first sensor coupled to the pitch actuator and configured to detect the holding torque of all of the plurality of fan blades and a second sensor coupled to the pitch actuator and configured to detect the holding torque of at least one fan blade of the plurality of fan blades. The pitch actuator is configured to take a corrective action when propeller whirl is detected outside of a predetermined limit.
