  • Patent number: 10921109
    Abstract: A sensor simultaneously determines a maximum rub depth and running clearance of a plurality of blade tips in a jet engine. The sensor includes an inductive component (e.g. inductor) and a resistive component comprising resistor portions each indicative of a depth into a layer of abradable material near the blade tips. When the blade tips move in proximity to the inductor, eddy currents in the blades generates a magnetic field that interact with the magnetic field generated by the inductor, which appears as an AC component in the current. When the blade tips abrade the abradable material, the resistor portions are severed and the DC current changes due to a change in resistance at the resistive component. An amplitude of the AC component indicates a running clearance as the blades move in proximity to the inductor. The frequency of the AC component indicates the rotational speed of the blades.

  • Patent number: 10267177
    Abstract: A rotor system lock for a gas turbine engine is described which blocks movement of rotating wheel assemblies relative to static vane assemblies in a gas turbine engine in order to block unintended rotation (or windmilling) of the gas turbine engine when it is exposed to high winds while at rest or to ram air during pre-launch flight and thereby avoid damage to components of the engine.

  • Patent number: 10113937
    Abstract: A system and method for monitoring a gap size of a gap between a seal holder and an adjacent disk in a compressor section of a gas turbine. An imaging device is used to generate at least one image of the gap, wherein a calibration image of the gap is generated when the gas turbine is in a cold state to provide a calibration gap size. An operational image of the gap is also generated when the gas turbine is in operation to provide an operational gap size. In addition, an enclosure that houses the imaging device is attached to an access port formed in the compressor section to provide a view of the gap for the imaging device. Wear is detected in a hook section of the compressor section when the operational gap size is less than the calibration gap size.
