摘要： Internal components of power generation machinery, including for example gas or steam industrial turbines as well as generators, are inspected a camera inspection system that is inserted and positioned within the machinery by an elongated cable carrier that has restricted cable flexure along a two-dimensional carrier cable flexure motion plane. A camera head that retains the camera is coupled to a distal end of the cable carrier. Embodiments also include a connector block coupled between the cable carrier distal end and the camera head. The connector block has a pivot axis coupled to the camera head for swinging the camera head along a camera head range of motion path that intersects the cable carrier flexure motion plane. Embodiments include a camera head swing motion drive system for selectively positioning the camera head along the camera head range of motion path.

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. The inspection system includes an articulated multi-axis inspection scope.

摘要： A method for removing a coating layer from a substrate structure. The method includes the steps of positioning a sheet of interface material on the substrate structure with a first, inner face of the interface material in engagement with a predetermined area of the coating layer, and exciting a second, outer face of the interface material with an ultrasonic frequency kinetic energy. The ultrasonic energy causes the predetermined area of the coating layer in contact with the inner face of the interface Material to be substantially completely removed.

摘要： An inspection apparatus (10) applying two dimensional nondestructive examination images onto a three dimensional solid model of a component (12) to display a virtual component (73) that may be manipulated to perform a nondestructive inspection. The two dimensional nondestructive examination images may be acquired from a plurality of views of the component in order to provide full coverage of the surface to be inspected, with appropriate stitching of images in regions of overlap between adjacent views. The two dimensional images (62) may be color or black and white photographs or ultraviolet or infrared images, for example. Multiple types of nondestructive examination images, results of inspection data evaluations, and design, operational and/or maintenance information may be displayed separately or jointly on the three dimensional solid model. Surface features of interest that are mapped as defined areas (76) on the three dimensional solid model may be displayed simultaneously in different views on 2D and 3D images of the virtual component.

摘要： An eddy current inspection probe provides multiple interchangeable configurations for enabling an inspector to reach most or all portions of most or all turbine blades within a combustion turbine by inserting the probe through an inspection port, without disassembling the turbine. The probe shaft contains the electronic signal wire for the inspection tip and a port for a video probe, thereby facilitating use of the video probe and protecting these components. The inspection tip connector at the end of the main shaft is pivotally secured to the shaft, and may be set at any desired angle by using a semirigid or rigid member passing through the shaft, and connected to lever within the handle. Any one of a plurality of probe tips and shaft extensions may be selected to configure the inspection probe to reach a desired location within the turbine.

摘要： Gas turbine inlet guide vane ice detection and control systems and methods that utilize active infra-red monitoring of inlet guide vanes, detection of ice formation on the guide vanes and elimination of the ice by altering properties of the gas turbine inlet intake airflow, such as by introducing compressed and/or heated air bled from the turbine. Ice has lower detectable emissivity intensity in the infra-red spectrum than ice-free inlet guide vane surfaces. Ice formation is inhibited by direct monitoring of inlet guide vane icing conditions, rather than by indirect empirical assumptions of ice formation based on atmospheric condition monitoring. Direct monitoring mitigates ice formation in real time without reliance on excessive use of gas turbine compressed or heated air bleed, which enhances turbine operational efficiency.

摘要： An on-line optical inspection and monitoring system is externally mounted to existing man way service access within the combustor housing. A replacement man way cover having an optical window is mounted to the combustor housing. One or more optical cameras are oriented so that the camera field of view (FOV) is directed through the man way cover optical window. The camera FOV is moved to plural positions within the combustion section, such as under control of an automated motion control system, and images are captured. Multiple images are combined to form a composite image, which may include an image of an entire transition within the combustion section. Visual images and/or infrared (IR) thermal images may be captured. Thermal image information is correlated with component temperature. Image information is utilized to determine vibration characteristics of the imaged components.

摘要： Internal components of gas and steam turbines are inspected with an optical camera inspection system that is capable of automatically and/or manually positioning the camera field of view (FOV) to an area of interest within the turbine along a pre-designated navigation path and capturing images with or without human intervention. Camera positioning and image capture can be initiated automatically or after receipt of operator permission. The inspection system includes an articulated multi-axis inspection scope with an optical camera that is inserted through a combustor nozzle access port, combustor and transition, so that the camera FOV captures the leading edge of Row 1 rotating turbine blades while the rotor is spinning at up to 1000 RPM. An illumination system strobe light and the camera image capture are synchronized with the blade rotation speed so that images of multiple or all blades may be obtained from a single inspection scope insertion point.

摘要： Inspecting a turbine includes positioning respective ends of a plurality of optical fibers within a high temperature region of the turbine wherein the respective first ends are aligned as a one-dimensional array. Energy emitted from an image area on a component of the turbine, is received at the ends of the optical fiber. The optical fibers convey the received energy to the other ends of the fibers that are located outside of the turbine. Outside the turbine an image of the respective other ends is captured, wherein the other ends are also aligned in a one-dimensional area. Additionally, for imaging a rotating component, a plurality of one-dimensional images of the other ends can be respectively captured at corresponding rotational positions of the component and used to create a two-dimensional image of the rotating component.
