Method And System For Monitoring Rotating Blade Health

View page
US Patent:
20140030092, Jan 30, 2014
Filed:
Jul 24, 2013
Appl. No.:
13/949441
Inventors:
Roger W. Heinig - Cocoa Beach FL, US
Jerry H. Griffin - Pittsburgh PA, US
Drew M. Feiner - Pittsburgh PA, US
International Classification:
F01D 21/00
US Classification:
416 1, 416 61
Abstract:
A method and system for establishing sets of blade frequency values for each rotating blade of a rotor assembly at two or more different points in time and determining an indication of blade health from the change in the blade frequency values is provided. Blade frequency values are determined by receiving measurements of vibratory responses from blade monitoring equipment () and processing via a processing device () vibration data as a system of rotating blades to extract a frequency of each blade. Sets of blade frequency values are compared to determine a change in the blade frequency values for each rotating blade to provide the indication of blade health.

Method And Apparatus For Reducing Vibration In A Turbo-Machine Blade

View page
US Patent:
55405517, Jul 30, 1996
Filed:
Aug 3, 1994
Appl. No.:
8/285665
Inventors:
Roger W. Heinig - Cocoa Beach FL
Assignee:
Westinghouse Electric Corporation - Pittsburgh PA
International Classification:
F01D 522
US Classification:
416190
Abstract:
Vibration in the blade of a turbo-machine is suppressed by the incorporation of both inner and outer restraints that inhibit deflections of the blade foils. The outer restraint comprises shroud, welded lugs or tie wires that divide the row of blades into a plurality of blade groups by connecting the blades in each group together. The number of blades in each group can be equal to the number of blades in the row divided by the harmonic of the rotor rotational frequency that is closest to the blade resonant frequency of concern. The inner restraint comprises welded lugs or tie wires disposed radially inward from the outer restraint that divide each blade group into a plurality of sub-groups, thereby further suppressing blade vibration. Since the length of the inner restraints is less than that associated with harmonic shrouds, the stresses in the inner restraint, as well as in the blades, due to radial growth of the rotor are maintained within acceptable levels.

Turbomachine Blade Fastening

View page
US Patent:
51526697, Oct 6, 1992
Filed:
Feb 11, 1991
Appl. No.:
7/653570
Inventors:
Roger W. Heinig - Cocoa Beach FL
Donald W. Barnes - Charlotte NC
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
F01D 530
US Classification:
416219R
Abstract:
Larger cutting tools which have inherently greater strength can be used to form mounting grooves for side-entry rotor blades when the bottom-most neck of the groove is increased in width in the machining process. The larger width leaves a gap on both sides of the bottom-most neck of the root at a location away from load bearing surfaces.

System And Method For Monitoring Synchronous Blade Vibration

View page
US Patent:
52068161, Apr 27, 1993
Filed:
Jan 30, 1991
Appl. No.:
7/647906
Inventors:
Peter D. Hill - Monroeville PA
Francis S. McKendree - Penn Hills PA
Charles W. Einolf - Murrysville PA
Paul F. Rozelle - Fern Park FL
Roger W. Heinig - Cocoa Beach FL
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
G01M 122
G01H 1100
US Classification:
364508
Abstract:
A system and method are provided for monitoring synchronous blade vibration in a turbo-machine. At least three sensors capable of detecting the arrival of each blade are arranged about the cylinder which surrounds the tips of the blades. The location of the sensors is selected to minimize the influence of errors in the data. To this end, and to simplify the installation of the sensors into the cylinder, the sensors may be non-uniformly spaced. The location of each sensor for purposes of constructing Fourier transforms is determined using the arrival times at the blades at each sensor, expressed as a fraction of a rotor revolution. The transform matrix is constructed for a predetermined discrete set of M harmonics, so that M harmonics are analyzed simultaneously, the number of harmonics which can be simultaneously analyzed is related to the number of sensors used. The blade arrival time data at each sensor, expressed as a fraction of a rotor revolution, is analyzed to determine the amplitude of the blade vibration at each of the harmonics selected for the set. The calculations are repeated for a variety of harmonic sets in order to accurately interpret the results in the event there is significant vibration at harmonics not included in the initial set.

Turbine Blade Attachment

View page
US Patent:
48243280, Apr 25, 1989
Filed:
May 22, 1987
Appl. No.:
7/053237
Inventors:
Frank A. Pisz - Titusville FL
Arthur S. Warnock - Bethlehem PA
Roger W. Heinig - Cocoa Beach FL
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
B21K 304
US Classification:
416219R
Abstract:
A structure for the root portion of a turbine blade and for the attachment grooves on a turbine rotor in conjunction with blades having integral shrouds and platforms as well as blades which are not attached to one another, blades which are joined by nonintegral shrouds and blades which do not include platforms. The invention is applicable to straight side entry blade roots and rotor grooves as well as curved side entry blades and curved rotor grooves. The invention results in reduced stress levels in the blade attachment structure by decreasing the land widths and increasing the fillet radii of curvature associated with each tang on a turbine blade root. In addition, the fillet radii of curvature are individually dimensioned to more uniformly distribute stress levels among blade root tangs. The reduction in land widths is accomplished by increasing land contact stresses for a given blade design.

Method Of Modifying Turbine Rotor Discs

View page
US Patent:
48933880, Jan 16, 1990
Filed:
Dec 8, 1988
Appl. No.:
7/281136
Inventors:
Dennis R. Amos - Rock Hill SC
Robert E. Clark - Orlando FL
Roger W. Heinig - Cocoa Beach FL
Stephen R. Reid - Newark DE
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
B21K 304
US Classification:
291568R
Abstract:
A method for modifying an original blade supporting disc (8) which is integral with a turbine rotor (2), and which has an original outline, in order to create a modified disc (8) which has an outline different from the original outline and which provides a blade-supporting region (10) of increased size, including the steps of: machining away portions (14,16) of the original disc (8) which protrude beyond the outline of the modified disc (8); building up the original disc (8) with weld metal past the outline of the modified disc (8) at all locations (14,20) where the outline of the original disc (8), after the machining step, is enclosed by the outline of the modified disc (8); and machining away parts of the weld metal to the outline of the modified disc (8).

Turbine Blade Health Monitoring System For Identifying Cracks

View page
US Patent:
20220403753, Dec 22, 2022
Filed:
Dec 3, 2020
Appl. No.:
17/771831
Inventors:
- Orlando FL, US
Roger W. Heinig - Cocoa Beach FL, US
International Classification:
F01D 21/00
G01M 15/14
Abstract:
A method of determining the location and size of a crack in a blade includes measuring a time of arrival of a tip of the blade at an angular position in a rotation, using the time of arrival to calculate a displacement of the tip of the blade, and using the displacements to calculate a first vibration condition and a second vibration condition for the blade. The method also includes comparing the first vibration condition and the second vibration condition for the blade to a predetermined baseline first vibration condition and a predetermined baseline second vibration condition for the blade to determine a change in the first vibration condition and a change in the second vibration condition, and using the magnitude of the change in the second vibration condition relative to the change in the first vibration condition to determine the likely location of the crack and using the magnitude of the change in the first vibration condition and the change in the second vibration condition to determine the size of the crack.
