International Classification:

G01B 3/30

US Classification:

73 179, 738658, 33549, 415118

Abstract:

A method for inspecting a turbine nozzle segment includes positioning the turbine nozzle segment on a base of a tool, with the outer forward face and the inner forward face of the turbine nozzle segment contacting a surface of the base. The outer wall is positioned between a first pedestal outer stand and a second pedestal outer stand of the tool, and the inner wall is positioned between a first pedestal inner stand and a second pedestal inner stand of the tool. At least one of a position, a depth and a width of a seal slot formed in a side edge of the outer wall and/or the inner wall is measured. At least one axial dimension of the turbine nozzle segment and at least one radial dimension of the turbine nozzle segment are measured.

International Classification:

G01B 5/02

US Classification:

33832, 33833, 33810

Abstract:

A measuring tool measures a trailing edge position of gas turbine nozzle. The tool includes a frame member attachable to at least one predefined reference point on the nozzle. At least one sliding member is slidable relative to the frame member and includes a measuring point engageable with the trailing edge. A position of the sliding member relative to the frame member is determinative of the trailing edge position.

International Classification:

G01B 3/14

US Classification:

33562, 33645

Abstract:

An inspection tool for a turbine bucket shroud includes: a clamp device for clamping a dovetail portion of a turbine bucket; a template plate provided with an aperture defined by a edge shaped to conform to a specified shape of the turbine bucket shroud, wherein the template is moveable to a location over the turbine bucket shroud in a direction toward the clamp device, and wherein, at the location, the aperture represents a design specification location for the turbine bucket shroud relative to the dovetail portion of the bucket. A measurement gauge is provided for measuring gaps between edges of the shroud and edges of the template aperture.

Assignee:

General Electric Company - Schenectady NY

International Classification:

B23Q 7/00

US Classification:

029559000

Abstract:

A manipulator assembly for supporting and manipulating a nozzle segment, for example of a gas turbine or a steam turbine. The assembly includes a vertical support member and a horizontal support member. The vertical support member is mounted for selective vertical displacement relative to a base and the horizontal support member is operatively coupled at a proximal end thereof to the vertical support member so as to be vertically displaced therewith and so as to be pivotable about a vertical axis of the vertical support member. A nozzle segment fixture is operatively coupled to a distal end of the horizontal support member for selectively supporting and manipulating a nozzle segment.
