Abstract

A multi-mode blade tip timing sensor (100; 200) includes a housing (201), a sensing coil (205) provided within the housing (201) and a powered exciter coil (207). The multi-mode blade tip timing sensor (100; 200) can operate in a first, sensing mode, and a second, de-icing mode. When operating in the first, sensing mode, a first current is provided to the powered exciter coil (207) to create a magnetic field such that a movement of one or more moving metallic fan blades (109) through the magnetic field creates a signal in the sensing coil (205). When operating in the second, de-icing mode, a second current is provided to the powered exciter coil (207) to induce an eddy current in a tip of the one or more moving metallic turbine fan blades (109), wherein the eddy current raises a temperature of the one or more moving metallic turbine fan blades (109) above an icing temperature.
