The invention discloses a turbine engine. 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 swirl 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 a holding torque of all of the plurality of fan blades, and a second sensor coupled to the pitch actuator and configured to detect a holding torque of all of the plurality of fan blades. The second sensor is coupled to the pitch actuator and is configured to detect a 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 it is detected that the propeller swirl is outside a predetermined limit.
