Filed:

Sep 30, 2010

Appl. No.:

12/894934

Inventors:

Scott Edmond Ellis - Easley SC, US
Adrian Lional Scott - Greer SC, US

International Classification:

F01D 5/08
B23P 15/04

US Classification:

416 95, 298897

Abstract:

A platform cooling arrangement in a turbine rotor blade having a platform, wherein the rotor blade includes an interior cooling passage, and wherein, in operation, the interior cooling passage comprises a high-pressure coolant region and a low-pressure coolant region, and wherein the platform includes a platform underside. The platform cooling arrangement may include: a first plate that resides inboard and in spaced relation to the platform underside and forming a first plenum; a second plate that resides inboard and in spaced relation to the first plate, the second plate forming a second plenum. The second plenum includes an inlet channel that connects to the high-pressure coolant region of the interior cooling passage, and the first plenum includes an outlet channel that connects to the low-pressure coolant region of the interior cooling passage.

International Classification:

F01D 5/08
B23P 15/04

US Classification:

416 95, 298897

Abstract:

A platform cooling arrangement in a turbine rotor blade having a platform at an interface between an airfoil and a root, wherein the rotor blade includes an interior cooling passage that in operation, includes at least a high-pressure coolant region and a low-pressure coolant region, and wherein the platform includes a platform underside. The platform cooling arrangement may include: a plate that comprises a plate topside; a channel formed on the plate topside, the channel comprising an upstream end and a downstream end, and being open through the plate topside such that, upon attaching the plate to the platform, the platform underside comprises a channel ceiling; a high-pressure connector that connects the upstream end of the channel to the high-pressure coolant region of the interior cooling passage; and a low-pressure connector that connects the downstream end of the channel to the low-pressure coolant region of the interior cooling passage.

International Classification:

F01D 5/08
B23P 15/04

US Classification:

416 95, 298897

Abstract:

A platform cooling configuration in a turbine rotor blade that includes platform slot formed through at least one of the pressure side slashface and the suction side slashface; a removably-engaged impingement insert that separates the platform into two radially stacked plenums, a first plenum that resides inboard of a second plenum; a high-pressure connector that connects the first plenum to the high-pressure coolant region of the interior cooling passage; a low-pressure connector that connects the second plenum to the low-pressure coolant region of the interior cooling passage.
