US Patent:

20060016191, Jan 26, 2006

Filed:

Jul 23, 2004

Appl. No.:

10/897788

Inventors:

Gregory Woodcock - Mesa AZ, US
Charles Silcox - Tempe AZ, US
Thomas Strangman - Prescott AZ, US
Luis Flamand - Phoenix AZ, US
Hiroshi Kawamura - Glendale AZ, US

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

F23R 3/42

US Classification:

060754000

Abstract:

A method for combined effusion and thick TBC cooling comprises a providing a substrate, depositing a thick TBC onto the substrate and laser drilling an array of effusion holes through the TBC coated substrate. The thick TBC has a columnar crack structure, which gives compliance and spall resistance. The microstructure of the segmentation microcracked TBC reduces cracking and chipping of the TBC during effusion hole laser drilling.

International Classification:

F23R 3/42

US Classification:

060754000

Abstract:

A combustor liner for shielding an engine from heat generated in a combustion zone includes a sheet with a cool surface for intercepting a cooling air stream and a hot surface enclosing the combustion zone, the combustor liner further including an array of effusion holes extending from the cool surface to the hot surface to allow a portion of the cooling air stream to pass through the effusion holes into the combustion zone, where a portion of the array includes a plurality of upstream-pointed effusion holes oriented such that each upstream-pointed effusion hole has an orientation obtuse to a direction of main flow in the combustion zone so as to control the momentum of cooling air passing into the combustion zone.

Assignee:

GENERAL ELECTRIC COMPANY - Schnectady NY

International Classification:

F02C 3/30

US Classification:

60 3952

Abstract:

The present application provides a combustor. The combustor may include an air flow path with a flow of air therein. A flow obstruction may be positioned within the air flow path and cause a wake or a recirculation zone downstream thereof. A number of fuel injectors may be positioned downstream of the flow obstruction. The fuel injectors may inject a flow of fuel into the air flow path such that the flows of fuel and air in the wake or the recirculation zone do not exceed a flammability limit.

International Classification:

F23C 3/00

US Classification:

60746

Abstract:

A gas turbine engine combustor is provided and includes an array of fuel nozzles, a combustion casing assembly disposed about the array of fuel nozzles and an end cap assembly disposed within the combustion casing assembly to define with the combustion casing assembly an axis-symmetric annulus through which fluid travels into each of the fuel nozzles, at least one of the combustion casing assembly and the end cap assembly being formed with lobed, three-dimensional contouring.

International Classification:

B05B 1/26

US Classification:

239518

Abstract:

A system for conditioning flow through a combustor includes a nozzle, and a shroud circumferentially surrounds at least a portion of the nozzle. The shroud defines an upstream opening, and a plurality of vanes extends radially inward from the shroud. A circumferential slot extends through the shroud between the upstream opening and the plurality of vanes.
