20100224772 | Apparatus and Method for Temperature Mapping a Rotating Turbine Component in a High Temperature Combustion Environment - Apparatus and method for temperature mapping a rotating component ( | 09-09-2010 |
20110229307 | Optical Monitoring System for a Turbine Engine - The monitoring system for a gas turbine engine including a viewing tube assembly having an inner end and an outer end. The inner end is located adjacent to a hot gas flow path within the gas turbine engine and the outer end is located adjacent to an outer casing of the gas turbine engine. An aperture wall is located at the inner end of the viewing tube assembly and an optical element is located within the viewing tube assembly adjacent to the inner end and is spaced from the aperture wall to define a cooling and purge chamber therebetween. An aperture is defined in the aperture wall for passage of light from the hot gas flow path to the optical element. Swirl passages are defined in the viewing tube assembly between the aperture wall and the optical element for passage of cooling air from a location outside the viewing tube assembly into the chamber, wherein swirl passages effect a swirling movement of air in a circumferential direction within the chamber. | 09-22-2011 |

20120281084 | INSPECTION SYSTEM FOR A COMBUSTOR OF A TURBINE ENGINE - 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. | 11-08-2012 |
20130088587 | HOUGH TRANSFORM APPROACH TO GAP MEASUREMENT IN BLADE INSPECTION - Two adjacent objects with a gap between the objects rotate in a hot atmosphere with a temperature greater than 300 F in a gas turbine. Automatic and accurate contactless measurement of the gap is performed by taking images of the gap. An image, preferably an infra-red image is taken from the gap, a processor extracts the two edges from the image of the gap. The processor also determines a line through the pixels of an edge by applying a Hough transform on the pixels. The edges are substantially parallel. A line substantially perpendicular to the lines is also determined. Using the substantially parallel lines and the line substantially perpendicular to the substantially parallel lines the processor determines a width of the gap. | 04-11-2013 |
20130194412 | SYSTEM AND METHOD FOR AUTOMATED OPTICAL INSPECTION OF INDUSTRIAL GAS TURBINES AND OTHER POWER GENERATION MACHINERY WITH ARTICULATED MULTI-AXIS INSPECTION SCOPE - 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. | 08-01-2013 |
