摘要:
Turbine blade insertion tool (20) facilitates supported vertical and lateral alignment of a turbine blade root (18) and corresponding rotor slot (14) from under a suspended rotor (12). The blade lift fixture (46) slidably retains the blade root while manually biasable slide (38) provides supported relative vertical alignment between the blade root and rotor slot Supported lateral root/slot alignment is provided by manually swinging the blade lift fixture (46) on three-dimensional motion capable swivel eye (50) and corresponding lift hook (44) that are coupled to the slide (38). The blade insertion tool (20) optionally is maneuverable on swivel rollers (24) under the rotor (12).
摘要:
A method, including: detecting in a nondestructive manner a marker (10, 12, 50, 70, 76, 78) that is fully submerged in a substrate (14) to obtain spatial information about the marker; detecting in a nondestructive manner the marker after a period of time to obtain a change in the spatial information; and using the change in the spatial information to determine a change in a dimension (30) of the substrate. The method may be used to measure creep in a gas turbine engine component.

Effusion cooling holes formed through a transition component provided in a combustion section of a gas turbine engine. The transition component directs a hot working gas from a combustion basket to a first row of vanes in a turbine section of the engine. The effusion cooling holes are formed through an outer wall of the transition component in a direction so that the flow of air through the effusion holes is in a direction substantially opposite to the bulk flow direction of the working gas through the transition component.
摘要:
Ultrasonic bolt inspection apparatus and methods facilitate in situ as well as bench non-destructive evaluation (NDE) inspection of fastening bolt distal ends and their mating nuts. The apparatus is coupled to an exposed end of a fastener bolt head, its exposed thread tip or to a mating nut. The apparatus retains a phased array ultrasonic probe that generates inspection scan data and a rotational position encoder that generates rotational position data. The probe is coupled to an ultrasonic inspection system analyzer, which converts scan data into inspection data that characterizes possible defects in the inspected bolt. A system controller is coupled to the analyzer and the rotational position encoder, correlating rotation position data and inspection data, in order to identify location and characteristics of possible defects in the inspected bolt end.

In a telemetry system (100) in a high-temperature environment of a combustion turbine engine (10), a wireless power-receiving coil assembly (116) may be affixed to a movable component (104) of the turbine engine. Power-receiving coil assembly (116) may include a radio-frequency transparent housing (130) having an opening (132). A lid (134) may be provided to close the opening of the housing. Lid (134) may be positioned to provide support against a surface (120) of the movable component. An induction coil (133) is disposed in the housing distally away from the lid and encased between a first layer (136) and a last layer (140) of a potting adhesive. Lid (134) is arranged to provide vibrational buffering between the surface (120) of the movable component (104) and the layers encasing the induction coil.
摘要:
Steam turbine engine cross over pipe or other pipe internal inspection is performed with a selectively steerable pipe inspection crawler apparatus with a chassis having a longitudinal axis, with front and rear Mechanum wheels capable of independently-selected forward or rearward driven rotational direction, for selectively steering the apparatus within the pipe interior under control of a human-machine interface (HMI). The crawler apparatus has at least one inspection camera having a field of view, for capturing images of a pipe interior that is also under control of the HMI. Embodiments of the crawler apparatus include a selectively orientable inspection camera and/or a deployable bore scope that is selectively deployed and retracted from a descending section of the cross over pipe.
摘要:
A method and system for determining a distance from a probe to an object includes generating a first electric field by applying a first signal across a first pair of electrodes aligned along a first axis and generating a second electric field by applying a second signal across a second pair of electrodes aligned along a second axis substantially perpendicular to the first axis. After generating the signals, a first change in the first signal due to the object interacting with the first electric field and a second change in the second signal due to the object interacting with the second electric field is concurrently detected. A distance of the object from the first and second pair of electrodes can be calculated based on a ratio of the first and second changes.

A vane array adapted to be coupled to a vane carrier within a gas turbine engine is provided comprising: a plurality of elongated airfoils comprising at least a first airfoil and a second airfoil located adjacent to one another; a U-ring; first connector structure for coupling a radially inner end section of each of the first and second airfoils to the U-ring; second connector structure for coupling a radially outer end section of each of the first and second airfoils to the vane carrier; a platform extending between the first and second airfoils; and platform connector structure for coupling the platform to one of the U-ring and the vane carrier.
摘要:
A method of braze repair for a superalloy material component. Following a brazing operation on the superalloy material, the component is subjected to an isostatic solution treatment, followed by a rapid cool down to ambient temperature under pressure The conditions of the isostatic solution treatment combined with the cool down at pressure function to both reduce porosity in the component and to solution treat the superalloy material, thereby optimizing superalloy properties without reintroducing porosity in the braze.
摘要:
A sealing component (61) for a turbine (15) positionable at an interface between a transition section (21) for carrying exhaust gas and a turbine inlet section (32). A U-shaped section (45) includes first and second legs (67, 69). When the sealing component is positioned at the interface, the legs extend about the turbine axis. A seal flange (75) connects to the U-shaped section. The positioned sealing component extends about the axis and in a direction away from the first leg. The seal flange faces the inner surface (76) of the flange. A flexible strip (79), positioned radially outward with respect to the seal flange, extends about the axis and extends along the axis between the U-shaped section and the flange. The flexible strip acts as a spring member pressing against the outer surface (96) of the flange.
