Stator Assembly For A Rotary Machine
US Patent:
7635251, Dec 22, 2009
Filed:
Jun 10, 2006
Appl. No.:
11/449900
Inventors:
Paul W. Duesler - Manchester CT, US
C. Vincent Loffredo - Newington CT, US
Matthew D. Nicolson - Glastonbury CT, US
Richard J. Pawlaczyk - Southington CT, US

Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F01D 11/02
F01D 17/16
F01D 17/16
US Classification:
4151737, 4152092, 415160
Abstract:
A stator assembly having a windage cover for structure adjacent to a cavity bounded by rotating elements in a rotary machine is disclosed. Various construction details are developed for damping vibrations in the windage cover as the windage cover bounds a cavity having swirling high velocity gases that are capable of transmitting acoustic energy and kinetic energy to adjacent structure. In one detailed embodiment, the windage cover in the uninstalled condition has diverging arms that are resiliently compressed during installation to exert a frictional force on the adjacent structure.
Method Of Forming A Windage Cover For A Gas Turbine Engine The Method Including Forming A Continuous Ring From A Sheet Of Metal And Bending And Cutting The Continuous Ring To Form At Least Two Arcuate Segments

Turbine Vane Flow Area Restoration Method
US Patent:
5522134, Jun 4, 1996
Filed:
Jun 30, 1994
Appl. No.:
8/270700
Inventors:
Jon G. Rowe - Middletown CT
Norman Pietruska - Durham CT
Richard J. Pawlaczyk - Hartford CT
Gilbert B. Wilcox - Somers CT
Norman Pietruska - Durham CT
Richard J. Pawlaczyk - Hartford CT
Gilbert B. Wilcox - Somers CT
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
B23P 1500
US Classification:
298891
Abstract:
A method for refurbishing or restoring a turbine vane or other airfoil to restore a desired flow area includes the steps of: providing a plate to be used to restore the flow area on the airfoil; cutting the plate into a desired shape; machining a series of tapers into the cut plate so that the cut plate has a single region with a substantially uniform thickness; overlaying a surface of the airfoil with the pre-cut, pre-shaped plate so that the substantially uniform thickness region is positioned over that part of the airfoil where the flow area is to be restored; and attaching the pre-cut, pre-shaped plate to the airfoil. The refurbishment or restoration method further includes heat treating the pre-cut, pre-shaped plate so that the plate softens and conforms to the shape of the airfoil surface.
Turbine Vane Having Dedicated Inner Platform Cooling
US Patent:
5344283, Sep 6, 1994
Filed:
Jan 21, 1993
Appl. No.:
8/008959
Inventors:
John W. Magowan - Longmeadow MA
Richard J. Pawlaczyk - Newington CT
Annette M. Pighetti - Andover CT
Richard A. Schwarz - Somers CT

Assignee:
United Technologies Corporation - Hartford CT
International Classification:
F01D 514
US Classification:
415115
Abstract:
A turbine vane for a gas turbine engine core adaptable to be operated in a variety of thrust regimes is disclosed. Various construction details are developed which provide cooling to an inner platform of the turbine vane. In one particular embodiment, a turbine vane includes a hollow core permitting cooling fluid to pass through the vane and an inner platform having a pocket disposed therein, the pocket being in fluid communication with the core. Heat is exchanged between the platform and the cooling fluid within the pocket. Cooling holes extend between the pocket and a flow surface of a platform to provide cooling of the flow surface.
