Abstract: A blackbody material application system for a turbine. The system includes a blackbody material supply and a moveable hose connected to the blackbody material supply wherein the hose sprays blackbody material onto a selected area within the turbine. The system also includes a rotatable bracket that holds the hose, wherein rotation of the bracket moves the hose toward the selected area within the turbine to enable application of the blackbody material onto the selected area. In addition, the system includes a motor for rotating the bracket and a moveable arm that holds the bracket wherein the bracket is inserted through an opening in the turbine and movement of the arm enables positioning of the bracket and hose in relative close proximity to the selected area suitable for spraying blackbody material onto the selected area.

Abstract: A robotically articulated inspection scope (56, 69) inserted into a pilot fuel nozzle port (58) of a turbine engine (20) for in-situ measurement of gaps (59) between tips of turbine blades (40A) and the surrounding shroud (44). A non-contact gap measuring device (52) on a distal end (79) of the scope may be navigated through a combustor (28) and transition duct (34) into a position proximate a blade tip gap. The scope may be controlled via computer (68) via a robotic drive (66) affixed to the pilot fuel nozzle port. Multiple scopes may be used to measure gaps (59A-D) at multiple azimuths of the turbine simultaneously. The turbine disk (37) may be rotated on its operating turning gear to sequentially measure each blade at each azimuth. The computer may memorize an interactively navigated path for subsequent automated positioning.

Abstract: Non-destructive evaluation optical inspection systems include video cameras or other reflective-photonic optical instruments, such as laser profilometers or 3D white light laser dimensional scanners, which are incorporated in a camera head. The camera head is coupled to a distal end of a self-supporting and shape-retaining elongate deformable deployment tether. The deployment tether is bendable, for insertion through cavities of power generation machines and orientation of the camera head field of view on the internal area of interest. The deployment tether is capable of being deformed repeatedly, for inspection of different areas of interest. In some embodiments, interchangeable camera heads are selectively coupled to the deployment tether, so that a kit or family of different optical inspection instruments are available to carry out multiple types of inspections within a single or multiple types of power generation machinery.

Abstract: A wearable device is provided that is configured to carry out an inspection of a gas turbine or other type of system. The device may include a processor, a data store, at least one output device, and at least one input device. The processor in the wearable device is responsive to inputs through the at least one input device and set of tasks stored in the data store corresponding to an inspection of a system to provide outputs through the at least one output device that prompt a user to gather data associated with the system being inspected using the wearable device while the wearable device is mounted to the user without the user holding the wearable device with the hand of the user. Also, the processor in the wearable device is configured to generate and output an inspection report responsive to the set of tasks and the data gathered using the wearable device.

Abstract: A method and an apparatus for measuring a deflection of a rotor of a turbomachine are presented. An optical fiber is inserted through a central bore of the rotor such that the optical fiber extends lengthwise through the bore along an axial direction of the rotor. The optical fiber is made up of a plurality of fiber optic strain sensors along the length of the optical fiber. A shape of the optical fiber is reconstructed based on strain information obtained from the plurality of the fiber optic strain sensors. A rotor deflection parameter is determined from the reconstructed shape of the optical fiber.
