Turbine engine having a fan speed sensor system

Abstract

A turbine engine includes a fan including a fan rotor assembly having a plurality of fan blades coupled to a fan disk, a fan frame that supports the fan, and a fan speed sensor system. The fan speed sensor system includes one or more fan speed sensors that sense a fan speed of the fan. The one or more fan speed sensors are positioned to sense the fan rotor assembly. A method of operating the turbine engine includes rotating the fan rotor assembly, sensing rotation of the fan rotor assembly with the one or more fan speed sensors, determining the fan speed of the fan based on the rotation of the fan rotor assembly, and controlling one or more components of the turbine engine based on the fan speed of the fan.
