Patent number: 10731506Abstract: 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.Type: GrantFiled: December 19, 2017Date of Patent: August 4, 2020Assignee: Raytheon Technologies CorporationInventors: Eli Cole Warren, Ian F.

Patent number: 10436612Abstract: 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.Type: GrantFiled: October 21, 2015Date of Patent: October 8, 2019Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Kevin Ford, Eli Warren, Corey A. Benoit, Edward F Dreger, Erik D. Rice, Mark W. Costa

Patent number: 10330455Abstract: A method is provided that involves a wall configured to circumscribe and be radially adjacent a rotor. During this method, a tri-axial capacitance probe is provided that includes a tri-axial conduit with an outer conductor member. The tri-axial capacitance probe is configured to output data indicative of a characteristic of the rotor. The tri-axial capacitance probe is configured within a wall aperture in the wall. The outer conductor member is electrically coupled with the wall. The wall is configured as a housing for the tri-axial capacitance probe.Type: GrantFiled: September 19, 2016Date of Patent: June 25, 2019Assignee: United Technologies CorporationInventors: Erik D.

Patent number: 7984656Abstract: A method includes rotating a rotor, measuring a rotor rotational time for the rotor to complete a revolution, determining a blade interval by dividing the rotor rotational time by a number of blades carried on the rotor, establishing an active hold-off time interval as a percentage of the blade interval time, directing a beam of light at the blades of the rotor using a laser, sensing light reflected from the blades, generating an output signal as a function of the sensed light, establishing a signal amplitude threshold, analyzing an amplitude of the output signal to trigger the active hold-off time interval when the amplitude reaches the signal amplitude threshold, and generating a blade arrival signal as a function of triggered active hold-off time intervals. The output signal is not analyzed within each active hold-off time interval.Type: GrantFiled: July 24, 2008Date of Patent: July 26, 2011Assignee: United Technologies CorporationInventors: Allison Clark Nicklous, Edward F.
