Appl. No.:

09/627050

Inventors:

Gregory Alan White - Cincinnati OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F04D 3100

US Classification:

415116, 4151701

Abstract:

A cooling shroud segment for a high pressure turbine that provides improved cooling in the region of the side panels from the midsection thereof forward to the leading edge and particularly in the midsection of the side panel. A shroud subassembly can be formed from a pair of such adjacent shroud segments with opposed adjacent side panels where the spacing of the outlets of the cooling air passages exiting from each of these adjacent side panels are staggered and where the adjacent panels have a spline seal slot with a humped section in at least the midsection of the side panel above and across the outlets of the cooling air passages exiting from the midsection of the side panel, in combination with a spline seal positioned in the gap between the opposed adjacent side panels. This shroud subassembly provides more uniform impingement cooling coverage and localizes more of the cooling air exiting the outlets from these passages in the midsection of the opposed side panels.

International Classification:

B23K 3112

US Classification:

228226, 228182

Abstract:

A method is provided for making, from a plurality of members brazed together, an article including an environmental resistant surface coating and a wear resistant surface portion. Prior to brazing, the members are assembled with at least one preform including the wear resistant material in a matrix including a first brazing alloy having a brazing temperature in a brazing temperature range. The assembly of members includes a second brazing alloy having a brazing temperature in the brazing temperature range. The assembly of members and wear resistant preform is heated in the brazing temperature range to provide a brazed article preform. Then the article preform is machined to a selected geometry and can be coated with the environmental coating.

Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D 904

US Classification:

415189, 4152092, 4152094, 2988922

Abstract:

A turbine nozzle includes segments of outer and inner bands supporting corresponding vane pairs. The bands adjoin each other at corresponding ends along splitlines, with each band having a forward land, an opposite aft land, and a middle land extending therebetween. The forward lands have a nominal aft-facing step, the aft lands have a nominal forward-facing step and the middle lands are nominally flush.

Inventors:

John Heyward - Loveland OH, US
Gregory White - Cincinnati OH, US
Michael Hagle - Mason OH, US

Assignee:

General Electric Company

International Classification:

B23P006/00

US Classification:

029/889100

Abstract:

The present invention provides a method of repairing a turbine nozzle segment having one or more vanes disposed between outer and inner bands. The method includes separating at least one of the outer and inner bands from the vanes. The vanes are cut through in close proximity to the band being replaced. A newly manufactured replacement band including protruding vane stubs is provided for each one of the original bands being replaced. The replacement band is attached to the vanes by welding.

International Classification:

F01D 2508

US Classification:

415115

Abstract:

To cool the shroud assembly in the high pressure turbine section of a gas turbine engine, high pressure cooling air is directed in metered flow to baffle plenums and thence through baffle perforations to impingement cool the rails and back surfaces of the shroud. Impingement cooling air then flows through elongated, convection cooling passages in the shroud sections and exits to flow along the shroud front surface with the main gas stream to provide film cooling. The aft rail of the shroud sections is provided with one or more cooling holes to impingement cool the annular retaining ring or C-clip retaining the shroud sections on the shroud hangers. This cooling air then travels aftward on the inboard side of the C-clip to provide convection cooling of the C-clip. In an alternative embodiment, cooling air is directed at the aft corners of the shroud base to avoid overheating.

Abstract:

A system and method for populating a store product information repository with information-rich content comprises capturing, by a sensor device, image data from a product of interest; executing an image recognition process to extract information-rich content from the captured image data in the form of text or graphics; outputting the extracted relevant content to a generic product description attribute; mapping the generic product description attribute to a product record; and storing the product record including the information-rich content for populating a product information repository.
