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.

    一种涡轮发动机,包括被构造为绕涡轮发动机的纵向中心线轴线旋转的多个风扇叶片、被构造为控制多个风扇叶片中的每一个的桨距角的桨距致动器、被构造为检测多个风扇叶片的保持扭矩的传感器组件、以及被构造为通过检测保持扭矩来监测多个风扇叶片中的螺旋桨旋流的控制器。传感器组件包括第一传感器和第二传感器,第一传感器联接到桨距致动器并且被构造为检测多个风扇叶片中的所有风扇叶片的保持扭矩,第二传感器联接到桨距致动器并且被构造为检测多个风扇叶片中的至少一个风扇叶片的保持扭矩。桨距致动器被构造为当检测到螺旋桨旋流在预定极限之外时采取校正动作。
