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 |

20150125267 | STANDARDIZED GAS TURBINE INSPECTION PORT SYSTEM - A standardized inspection port system with common inspection port bodies and port plugs are incorporated in plural inspection locations within a gas turbine engine casing to facilitate internal engine inspection. The inspection ports preferably have identical internal diameter, stub flange dimensions and axial length from the gas turbine casing inspection seat to the stub flange for standardized mounting of inspection instruments at different locations about the turbine. The inspection port system components are preferably axially and radially aligned along the turbine casing for establishing a common reference position along all turbine blade/vane rows. The port plug incorporates a magnetically attractive pole piece for concentration or redirection of an attractive magnetic field circuit generated by an inspection port plug service tool during plug insertion or retrieval. Magnetic attraction to a service tool enhances controlled plug guidance and reduces likelihood of inadvertent plug loss within the turbine casing. | 05-07-2015 |
20150240657 | METHOD FOR INSPECTING A TURBINE ENGINE ROTOR WITH A ROTOR DISC CAVITY INSPECTION APPARATUS - Turbine engine rotor corresponding thru-bolts and disc cavities are inspected with a camera inspection system that includes one or both of a thru-bolt male threads inspection apparatus and a rotor disc cavity inspection apparatus. The disc cavity inspection scope apparatus is insertable in one or more of the desired rotor disc cavities and orients an attached inspection camera field of view generally transverse to the circumferential wall in the rotor disc that defines the cavity. Preferably inspection scope apparatus insertion into the disc cavities is performed with a motion control system that monitors spatial position of the camera field of view relative to the recess circumferential wall. The plural camera cavity circumferential wall images are desirably combined to form a composite image of a desired portion of or the entire disc cavity circumferential surface, which aids their inspection evaluation and provides an archived composite image of the surface. | 08-27-2015 |
20150241303 | METHOD FOR INSPECTING A TURBINE ENGINE ROTOR WITH A THRU BOLT THREADS INSPECTION APPARATUS - Turbine engine rotor corresponding thru-bolts and disc cavities are inspected with a camera inspection system that includes one or both of a thru-bolt male threads inspection apparatus and a rotor disc cavity inspection apparatus. The thru-bolts threads inspection apparatus engages the male threads and advances along the bolt threads pattern, selectively capturing camera images at desired spatial positions along the threads pattern. The plural camera threads images are desirably combined to form a composite image of a desired portion of or the entire thru-bolt male threads profiles, which aids their inspection evaluation and provides an archived composite image of the profiles. | 08-27-2015 |
