Abstract
A turbine engine includes a fan having a plurality of fan blades, a nacelle that surrounds the fan, and a fan blade sensor system. The fan blade sensor system includes a plurality of fan blade sensors disposed in the nacelle to sense the plurality of fan blades as the plurality of fan blades rotates. The fan blade sensor system also includes a controller that determines a fan speed of the fan based on a rotational time between the fan blades as sensed by the plurality of fan blade sensors.

A turbine engine comprising:
- a fan having a plurality of fan blades;
- a nacelle that surrounds the fan;
- and
- a fan blade sensor system comprising a plurality of fan blade sensors disposed in the nacelle to sense the plurality of fan blades as the plurality of fan blades rotates, and a controller that determines an asynchronous flutter of the plurality of fan blades based on a rotational difference in time spacing between different fan blades of the plurality of fan blades as sensed by the plurality of fan blade sensors, and, when the controller determines the asynchronous flutter of the plurality of fan blades, the controller determines a fan speed of the fan based on a passing time of a single fan blade of the plurality of fan blades on consecutive revolutions to minimize noise.
