Abstract: An axial location of a time of arrival probe may be determined by attaching a wedge comprising a distal surface to a blade. A first edge of the distal surface and a second edge of the distal surface may form an angle. The axial location of the probe may be determined based on the angle and a distance extending from the first edge of the wedge to the blade.

Abstract: A capacitance probe monitors the distance between a blade tip and a fan, compressor or turbine case. The capacitance probe may be attached to a liner, and may travel with the liner as it radially expands due to thermal changes. The capacitance probe may include a circuit board sensor with a metallic plate, and one or more capacitors. The metallic plate may be encapsulated within an insulating material. A plurality of soft leads may be in electrical communication with the circuit board sensor, allowing a lower lead weight, reduced size and increased flexibility. The soft leads may also be embedded in the liner. In this way, the capacitance probe can record more accurate distance measurements and promote a gas turbine engine's continued and efficient operation.

Abstract: A wear indicator for detecting blade clearance in a gas turbine engine includes a capacitor connected to a first conductor and a second conductor. The capacitor includes a multiple of layers arranged transverse to a rub direction, each layer separated by an insulator and including a first plate, a second plate, and a dielectric between the first plate and the second plate. A method of detecting blade clearance in a gas turbine engine, includes determining a change in capacitance between the first and second capacitance and determining an amount of material removed from the wear indicator by the blade corresponding to the change in capacitance.
