摘要： An inspection system formed at least from an inspection system housing including at least one internal chamber that supports an extendible camera support shaft extending distally through a pilot nozzle port into a combustor of a gas turbine engine is disclosed. The inspection system may include a camera capable of capturing high quality images together with position coordinates. Thus, the inspection system enables images in a combustor of a gas turbine engine to be captured and recaptured at a subsequent outage so that the images may be analyzed and compared for preventive maintenance, troubleshooting, and the like. The inspection system may include three degrees of freedom for the camera mounted on the extendible camera support shaft.

摘要： Internal components of power generation machinery, such as gas and steam turbines are inspected with an optical camera inspection system that is capable of automatically positioning the camera field of view (FOV) to an area of interest within the machinery along a pre-designated navigation path and capturing images without human intervention. Automatic camera positioning and image capture can be initiated automatically or after receipt of operator permission. The pre-designated navigation path can be defined by operator manual positioning of an inspection scope within the power machine or a similar one of the same type and recording of positioning steps for future replication. The navigation path can also be defined by virtual simulation.

摘要： A method for detecting surface discontinuities in a test specimen. The method includes applying a one or more substances including a detection medium to the test specimen wherein the detection medium enters at least one surface discontinuity in the test specimen. The specimen surface is monitored for discontinuity signatures produced by the detection medium. The monitoring includes monitoring the detection medium to detect a temperature differential indicative of a surface discontinuity in the test specimen wherein the discontinuity signatures include a warm signature emitted by the detection medium that has entered the surface discontinuity.

摘要： An inspection system includes a cooling apparatus for conducting visual inspections within operating temperature environments, such as, for example, the interior of a combustion turbine shortly after shut down. The cooling apparatus provides cooling for an inspection probe such as a video borescope. The cooling apparatus includes an articulating guide tube having a control portion, an elongate flexible portion and an articulating section. The video borescope is inserted down through the articulating guide tube. A thermal protective sleeve surrounds and thermally insulates a portion of the articulating guide tube. Vortex coolers circulate cooled, compressed air within the cooling apparatus, thereby maintaining a cool video borescope operating temperature.

摘要： An object in a hot atmosphere with a temperature greater than 400 F in a gas turbine moves in a 3D space. The movement may include a vibrational movement. The movement includes a rotational movement about an axis and a translational movement along the axis. Images of the object are recorded with a camera, which may be a high-speed camera. The object is provided with a pattern that is tracked in images. Warpings of sub-patches in a reference image of the object are determined to form standard format warped areas. The warpings are applied piece-wise to areas in following images to create corrected images. Standard tracking such as SSD tracking is applied to the piece-wise corrected images to determine a movement of the object. The image correction and object tracking are performed by a processor.
