Bucket Platform Cooling Scheme And Related Method

US Patent:
6478540, Nov 12, 2002
Filed:
Dec 19, 2000
Appl. No.:
09/739445
Inventors:
Nesim Abuaf - Lincoln City OR
Kevin Joseph Barb - Halfmoon NY
Sanjay Chopra - Greenville SC
David Max Kercher - Ipswich MA
Iain Robertson Kellock - Simpsonville SC
Dean Thomas Lenahan - Cincinnati OH
Sankar Nellian - Mauldin SC
John Howard Starkweather - Sharonville OH
Douglas Arthur Lupe - Ballston Lake NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 518
US Classification:
416 1, 416 97 R, 416193 A
Abstract:
A turbine bucket includes an airfoil extending from a platform, having high and low pressure sides; a wheel mounting portion; a hollow shank portion located radially between the platform and the wheel mounting portion, the platform having an under surface. An impingement cooling plate is located in the hollow shank portion, spaced from the under surface, and the impingement plate is formed with a plurality of impingement cooling holes therein.

Method For Controlling Coolant Flow In Airfoil, Flow Control Structure And Airfoil Incorporating The Same

US Patent:
6589010, Jul 8, 2003
Filed:
Aug 27, 2001
Appl. No.:
09/682373
Inventors:
Gary Michael Itzel - Simpsonville SC
Sanjay Chopra - Greenville SC
Thomas Nelson Toornman - Buford GA
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 906
US Classification:
415115, 415 1, 416 96 R
Abstract:
A coolant flow control structure is provided to channel cooling media flow to the fillet region defined at the transition between the wall of a nozzle vane and a wall of a nozzle segment, for cooling the fillet region. In an exemplary embodiment, the flow control structure defines a gap with the fillet region to achieve the required heat transfer coefficients in this region to meet part life requirements.

Insert Metering Plates For Gas Turbine Nozzles

US Patent:
6733229, May 11, 2004
Filed:
Mar 8, 2002
Appl. No.:
10/092572
Inventors:
Steven S. Burdgick - Schenectady NY
Gary Itzel - Greenville SC
Sanjay Chopra - Schenectady NY
Nesim Abuaf - Schenectady NY
Victor H. Correia - Milton Mills NH
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 906
US Classification:
415 1, 415116, 416 96 A, 416 97 R
Abstract:
The invention comprises a metering plate which is assembled to an impingement insert for use in the nozzle of a gas turbine. The metering plate can have one or more metering holes and is used to balance the cooling flow within the nozzle. A metering plate with multiple holes reduces static pressure variations which result from the cooling airflow through the metering plate. The metering plate can be assembled to the insert before or after the insert is inserted into the nozzle.

Intensively Cooled Trailing Edge Of Thin Airfoils For Turbine Engines

US Patent:
7722326, May 25, 2010
Filed:
Mar 13, 2007
Appl. No.:
11/717238
Inventors:
Alexander R. Beeck - Orlando FL, US
Sanjay Chopra - Orlando FL, US
Assignee:
Siemens Energy, Inc. - Orlando FL
International Classification:
F01D 5/18
US Classification:
416 97R, 416 92
Abstract:
A cooling system designed to cool the trailing edge of a turbine blade usable in rear stages of a turbine engine. The turbine blade may have a leading edge cooling cavity and a trailing edge cooling cavity separated by an impingement rib. The cooling system may exhaust cooling fluids through the tip of the turbine blade rather than through the trailing edge of the turbine blade to prevent premature failure at the trailing edge of the turbine blade.

Impingement Jets Coupled To Cooling Channels For Transition Cooling

US Patent:
7886517, Feb 15, 2011
Filed:
May 9, 2007
Appl. No.:
11/801306
Inventors:
Sanjay Chopra - Orlando FL, US
Bradley T. Youngblood - Oviedo FL, US
Robert W. Dawson - Oviedo FL, US
Assignee:
Siemens Energy, Inc. - Orlando FL
International Classification:
F23R 3/42
F23R 3/46
US Classification:
60 3937, 60752, 60754
Abstract:
Embodiments of a transition () of the present invention comprise a cooling channel () defined in part by an outer wall () and an inner wall (). The cooling channel () also comprises lateral side walls (). Two or more subdomains (AA, BB, A, B, B, C, C, D) of impingement jets () are provided through the outer wall (), and one or more metering outlets () is provided through the inner wall (), all communicating with a respective channel (). The impingement jets of each respective subdomain are designed to supply cooling fluid to one of the one or more metering outlets. Further to the impingement jets () their size, shape, spacing, and arrangement with regard to the metering outlet () are such that a desired cooling of the inner wall () is provided during normal gas turbine operations through advantageous impingement cooling at points along the surface of the inner wall () that defines the cooling channel ().

Nozzle Diaphragm Inducer

US Patent:
2013032, Dec 5, 2013
Filed:
Jun 4, 2012
Appl. No.:
13/487332
Inventors:
Sanjay Chopra - Schenectady NY, US
Michael Joseph Boss - Ballston Spa NY, US
Tai Joung Kim - Schenectady NY, US
Jason Paul Mortzheim - Gloversville NY, US
Nestor Hernandez Sanchez - Schenectady NY, US
Howard Michael Brilliant - Niskayuna NY, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01K 7/16
F01D 7/00
US Classification:
415 1, 4152081
Abstract:
The present application provides a steam turbine driven by a flow of steam. The steam turbine may include a rotor, a number of nozzles positioned about the rotor, and a number of nozzle diaphragms. One or more of the nozzle diaphragms may include an inducer.

Turbine Stator Vane Segments Having Combined Air And Steam Cooling Circuits

US Patent:
5634766, Jun 3, 1997
Filed:
Mar 31, 1995
Appl. No.:
8/414697
Inventors:
Francisco J. Cunha - Schenectady NY
David A. DeAngelis - Voorheesville NY
Theresa A. Brown - Clifton Park NY
Sanjay Chopra - Albany NY
Victor H. S. Correia - New Labanon NY
Daniel R. Predmore - Clifton Park NY
Assignee:
General Electric Co. - Schenectady NY
International Classification:
F01D 904
F01D 906
US Classification:
415115
Abstract:
Turbine stator vane segments have inner and outer walls with vanes extending therebetween. The inner and outer walls are compartmentalized and have impingement plates. Steam flowing into the outer wall passes through the impingement plate for impingement cooling of the outer wall surface. The spent impingement steam flows into cavities of the vane having inserts for impingement cooling the walls of the vane. The steam passes into the inner wall and through the impingement plate for impingement cooling of the inner wall surface and for return through return cavities having inserts for impingement cooling of the vane surfaces. The trailing edge is air-cooled.
