Abstract: An apparatus includes a blade outer air seal (BOAS), a measurement instrument adapter, and a measurement instrument. The BOAS includes at least one first channel configured to permit air to flow from an entry point of the at least one first channel to an exit point of the at least one first channel. The measurement instrument adapter includes at least one second channel configured to permit air to flow from an entry point of the at least one second channel to an exit point of the at least one second channel. The measurement instrument adapter is disposed within a first receptacle of the measurement instrument adapter configured to receive the measurement instrument. The measurement instrument adapter is disposed within a second receptacle of the BOAS configured to receive the measurement instrument adapter. The apparatus is configured for installation in a gas-turbine engine.

Abstract: An adapter for pulling a lead wire through an engine assembly comprises a lead connector configured to connect with a lead wire connector associated with a lead wire. A width of the lead connector is equal to or less than a width of the lead wire connector. A pull connector is configured to connect with a pull cable threaded through the engine assembly to enable a pulling force to be applied to the adapter. The pull connector is integrated with the lead connector.

Abstract: A gas turbine engine includes a fan duct, an engine casing, and a gaspath casing. A thermal imaging device is integrated with the gas turbine engine. The thermal imaging device includes: a main body comprising processing circuitry, where the main body is mountable to the fan duct or a mounting structure separate from the fan duct. The thermal imaging device includes a probe mounted to the engine casing. The probe includes one or more sensors configured to detect thermal energy, and the probe is configured to transmit an optical signal based on the detected thermal energy, to an aperture of the main body, over an air gap between the probe and the main body. The processing circuitry is configured to provide temperature information in response to processing the optical signal.

Abstract: An adapter includes a cup having an inner portion proportioned to retain a sensor probe such that a face of the sensor probe is exposed to an interior of a gas turbine, where the inner portion includes a sidewall and a lip. The cup also includes one or more channels extending along the sidewall and across the lip. The adapter includes a mounting flange, where the one or more channels are configured to direct a gas from an exterior of the gas turbine across the face of the sensor probe.

Abstract: A lead cooling assembly includes a cooling jacket including a tubular section having an exterior portion and an interior portion, where the interior portion is proportioned to surround a probe lead and provide space for a flow of a gaseous coolant. The lead cooling assembly also includes an intake configured to admit the gaseous coolant into the interior portion of the cooling jacket. The lead cooling assembly further includes a collar configured to fit over the exterior portion of the cooling jacket, where the collar includes one or more exit holes configured to pass the gaseous coolant out of the interior portion of the cooling jacket.
