Methods And Apparatus For Rotary Machinery Inspection

View page
US Patent:
7174788, Feb 13, 2007
Filed:
Dec 15, 2003
Appl. No.:
10/736363
Inventors:
Gerald John Czerw - Scotia NY, US
Laurie Diane Donovan - Cat Spring TX, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01N 29/04
US Classification:
73620
Abstract:
A method of non-destructive evaluation (NDE) testing a component of an assembly is provided. The method includes positioning a transducer on a face of the component, transmitting ultrasonic waves into the component at a plurality of steering angles, receiving ultrasonic echoes, wherein each received echo is indicative of an acoustic impedance interface within the component, and analyzing the ultrasonic echoes.

Filed:

Appl. No.:
11/617198
Inventors:
Gerald John Czerw - Scotia NY, US

Method Of Inspecting Turbine Wheel And Bucket Finger Dovetails For Cracks

US Patent:
6725722, Apr 27, 2004
Filed:
Feb 11, 2003
Appl. No.:
10/361643
Inventors:
Thomas Francis Murphy - Scotia NY
Gerald John Czerw - Scotia NY
Edward Lee Bentzel - Latham NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01N 2904
US Classification:
73628, 73633, 73641
Abstract:
An ultrasonic probe is used to inspect wheel and bucket dovetails of turbines for cracks in the material surrounding pinholes and pins securing the buckets and wheel to one another. Only a minimum number of pins, for example, one of three radially aligned pins securing the bucket and wheel dovetails to one another at every other circumferential position of the pins about the wheel may be removed. A phased array ultrasonic probe is inserted into the excavated pinhole and provides a circumferential scan of the finger dovetails to detect cracks in adjacent pinholes. As an alternative, a probe having one or more piezoelectric elements providing one or more radial beams may be mechanically rotated in the pinhole. Statistical sampling may be used as an indicator of crack formation. Thus, in situ inspection is performed without removal of buckets from the wheel and with only a minimum number of pins being removed.
