An inspection system includes a thermographic sensor configured to capture thermographic data of a component having holes as a fluid is pulsed toward the holes, and one or more processors configured to temporally process the thermographic data to calculate temporal scores and spatial scores for the corresponding holes. The scores can be used to obtain a reference dataset and a test dataset. A performance score can be assigned to the component based on the difference between the datasets.

An imaging apparatus for imaging a rotating component is shown. The imaging apparatus has a proximal end configured to be attached to the rotating component, along with a distal end. The imaging apparatus has located within it a convex mirror at the distal end, which has a reflective surface which is directed toward the proximal end and having a field of view wider than the imaging apparatus. The imaging apparatus also has located within it a camera at the proximal end, the camera being directed towards to distal end and having a field of view which includes the mirror.

Systems and methods include a blade monitoring system. The blade monitoring system includes a processor. The processor is configured to receive a sensor signal from a sensor configured to observe a blade of the turbomachinery. The processor is also configured to derive a measurement based on a marking disposed on the blade of the turbomachinery, wherein the marking comprises a discrete feature; and to display the measurement to an operator of the turbomachinery

A turbine engine having an optical imaging system with a housing configured for mounting to a wall of the turbine engine, a camera located in the housing, a hollow probe extending from the housing and having a longitudinal axis, an image receiving device at an end of the hollow probe and communicably coupled with the camera, and method for operating same.

A fuel leak detection system for hydrogen fuel system including a monitored component. The fuel leak detection system including a sensor and controller communicatively coupled to the sensor. The sensor is positioned to monitor at least a portion of the monitored component. The sensor is configured (i) to sense a parameter corresponding to a hydrogen fuel leak of the monitored component and (ii) to generate an output. The controller is configured (i) to receive the output of the sensor, (ii) to determine, based on the output of the sensor, if a leak has occurred in the monitored component, and (iii) to generate an output indicating a fuel system leak when the controller determines that the leak has occurred in the monitored component. The monitored component may be a component of one of a fuel tank, a power generator, and a fuel delivery assembly.

Internal components of power generation machinery, such as gas turbine engines, are inspected with a spherical, optical-camera inspection system, mounted within a camera housing on a distal end of a compact diameter, single-axis inspection scope. The inspection scope includes nested, non-rotatable telescoping tubes, which define an extension axis. Circumscribing, telescoping tubes have anti-rotation collars, which are in sliding engagement with extension tracks on a circumferential surface of an opposing, nested tube, for ease of extension and retraction of the camera during visual inspections of power generation machinery. The camera is advanced and/or retracted along a scope extension axis by nested, drive tubes, which incorporate at least one external drive screw on a circumscribed drive tube and corresponding female threads formed in a circumscribing drive tube. The spherical camera has a 360-degree field of view, and captures images without rotation about the scope extension axis.

A method for testing a turbojet engine for an aircraft in a U-shaped or open-air test bench includes: (a) visual inspection of the test bench and of the turbojet engine; and (b) testing of the turbojet engine in the test bench. During the test, the turbojet engine bears test equipment with sensors, other sensors being housed in the test bench. The test bench includes an augmented-reality system performing the step of (a) visual inspection in the test bench in order to detect a possible major anomaly in the test bench. The step of (a) visual inspection is intended to check the conformity of the test conditions, and especially those of the test equipment or that of the test bench as a whole. The method performs the step of (b) testing only in the absence of an anomaly.
