6844518, Jan 18, 2005
Filed:
Dec 22, 2003
Appl. No.:
10/743517
Inventors:
Todd Coons - Casa Grande AZ, US
Edward Pietraszkiewicz - Southington CT, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
B23H 104
B23H 726
B23H 910
B23H 914
US Classification:
219 6915, 219 6911
Abstract:
A hole-drilling guide for directing a flexible hole-drilling instrument includes; a body made of an electrically insulating material, at least one inlet aperture penetrating a face of the body, at least one exit aperture penetrating a face of the body and a hollow, nonlinear raceway linking the inlet and exit apertures.

Airfoil With Three-Pass Serpentine Cooling Channel And Microcircuit

View page
US Patent:
7131818, Nov 7, 2006
Filed:
Nov 2, 2004
Appl. No.:
10/979597
Inventors:
Frank J. Cunha - Avon CT, US
Bret Teller - Meriden CT, US
Young Chon - Manchester CT, US
Dominic Mongillo - West Hartford CT, US
Edward F. Pietraszkiewicz - Southington CT, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F01D 5/16
US Classification:
416 97R, 415115
Abstract:
An airfoil, and in a disclosed embodiment a rotor blade, has a serpentine cooling path. To best account for the Coriolis effect, the paths of the serpentine cooling channel have trapezoidal cross-sections. An area of the rotor blade between a smaller side of the trapezoidal-shaped paths, and a facing wall of the rotor blade has high thermal and mechanical stresses, and is a challenge to adequately cool. A microcircuit, which is a very thin cooling circuit having crossing pedestals, is embedded into the blade in this area. The microcircuit provides additional cooling, and addresses the challenges with regard to cooling these areas.

Turbine Airfoil Cooling Passageway

View page
US Patent:
7150601, Dec 19, 2006
Filed:
Dec 23, 2004
Appl. No.:
11/021152
Inventors:
Edward F. Pietraszkiewicz - Southington CT, US
John C. Calderbank - Glastonbury CT, US
Andrew D. Milliken - Middletown CT, US
Jeffrey R. Levine - Wallingford CT, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F01D 5/18
US Classification:
416 97R, 415115
Abstract:
An internally cooled gas turbine engine turbine vane has an outboard shroud and an airfoil extending from an outboard end at the shroud to an inboard end. A cooling passageway has an inlet in the shroud, a first turn at least partially within the airfoil, a first leg extending from the inlet inboard through the airfoil to the first turn, and a second leg extending from the first turn. A dividing wall is in the passageway and has an upstream end in an outboard half of a span of the airfoil and has a plurality of vents. The vane may be formed as a reengineering of a baseline configuration lacking the dividing wall.

Cooled Rotor Blade

View page
US Patent:
7195448, Mar 27, 2007
Filed:
May 27, 2004
Appl. No.:
10/855188
Inventors:
Jeffrey R. Levine - Wallingford CT, US
Edward Pietraszkiewicz - Southington CT, US
John Calderbank - Glastonbury CT, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F01D 5/18
US Classification:
415115, 416 96 R, 416 97 R
Abstract:
A rotor blade is provided that includes a root, a hollow airfoil, and a conduit disposed within the root. The hollow airfoil has a cavity defined by a suction side wall, a pressure side wall, a leading edge, a trailing edge, a base, and a tip. An internal passage configuration is disposed within the cavity. The configuration includes a first radial passage, a second radial passage, a rib disposed between and separating the first radial passage and second radial passage, a plurality of crossover apertures disposed within the rib, and a plurality of trip strips disposed within the second radial passage. The trip strips are attached to an interior surface of one or both of the pressure side wall and the suction side wall. The trip strips are disposed within the first radial passage at an angle α that is skewed relative to a cooling airflow direction within the first radial passage, and positioned such that each of the plurality of trip strips converges toward the rib. The rib end of at least a portion of the plurality of trip strips is located between a pair of adjacent crossover apertures.

Heat Transferring Cooling Features For An Airfoil

View page
US Patent:
7217095, May 15, 2007
Filed:
Nov 9, 2004
Appl. No.:
10/984216
Inventors:
Edward F. Pietraszkiewicz - Southington CT, US
Christina Botnick - Stafford Springs CT, US
Todd Coons - Gilbert AZ, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F01D 5/18
US Classification:
416 97R
Abstract:
A turbine blade airfoil assembly includes a cooling air passage. The cooling air passage includes a plurality of impingement openings that are isolated from at least one adjacent impingement opening. The cooling air passage is formed and cast within a turbine blade assembly through the use of a single core. The single core forms the features required to fabricate the various separate and isolated impingement openings. The isolation and combination of impingement openings provides for the augmentation of convection and film cooling and provide the flexibility to tailor airflow on an airfoil to optimize thermal performance of an airfoil.

Impingement Cooling Of Large Fillet Of An Airfoil

View page
US Patent:
7220103, May 22, 2007
Filed:
Oct 18, 2004
Appl. No.:
10/967557
Inventors:
Frank J. Cunha - Avon CT, US
Jason E. Albert - West Hartford CT, US
Edward F. Pietraszkiewicz - Southington CT, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F01D 5/18
US Classification:
416 97R, 416193 A
Abstract:
A gas turbine engine blade has a relatively large fillet to improve the characteristics of the air flow thereover. The fillet has a thin wall which, together with an impingement rib, defines a fillet cavity therebetween, and cooling air is provided to flow through impingement holes in the impingement rib and impinge on the rear surface of the fillet. The impingement holes are elongated in cross sectional shape with their elongations being orient in a direction generally transverse to a radial direction.

Dirt Separator For Gas Turbine Air Supply

US Patent:
7284953, Oct 23, 2007
Filed:
Aug 29, 2005
Appl. No.:
11/214238
Inventors:
Richard Silverman - Tolland CT, US
Barry Beckwith - Coventry CT, US
Lisa O'Neill - Manchester CT, US
Edward F. Pietraszkiewicz - Southington CT, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F04D 29/70
US Classification:
4151212, 60 39092
Abstract:
A gas turbine engine is provided with a radially outer cooling air flow. A dirt separator is placed in the path of the radially outer cooling air flow, and includes a radially outer leg that defines a space to capture dirt or other impurities. A radially inner leg of the dirt separator includes open air flow passages to allow air to flow through the inner leg and downstream to cool various components within the gas turbine engine.

US Classification:
416 97A, 416232, 29889721, 298897
Abstract:
A method for manufacturing a turbine engine component comprises the steps of forming a first half of an airfoil portion of the turbine engine component and forming a first cooling microcircuit having at least one passageway on an exposed internal wall of the first half of the airfoil portion. The method further comprises forming a second half of the airfoil portion of said turbine engine component, forming a second cooling microcircuit having at least one passageway on an exposed internal wall of the second half of the airfoil portion, and placing the first half in an abutting relationship with the second half after the cooling microcircuits have been formed and inspected.
