Fluid Detection In Turbine Engine Components
view source
US Patent:

8174699, May 8, 2012
Filed:

Jul 22, 2010
Appl. No.:

12/841305
Inventors:

Erwan Baleine - Orlando FL, US
Assignee:

Siemens Energy, Inc. - Orlando FL
International Classification:

G01N 21/00
US Classification:

356432, 356135, 356436
Abstract:

A system for detecting the presence of one or more fluids in a rotating component of a gas turbine engine. A first reflector structure includes a first face that receives light from the light source. The first reflector structure reflects at least a substantial portion of the received light from the light source if a second face thereof is in the presence of a first fluid and does not reflect a substantial portion of the received light from the light source if the second face is in the presence of a second fluid. A reflection receiver structure receives light reflected by the first reflector structure. If the reflection receiver structure receives a first predetermined amount of light reflected by the first reflector structure it can be determined that the second face of the first reflector structure is not in the presence of the second fluid.

US Patent:

8184151, May 22, 2012
Filed:

Sep 18, 2009
Appl. No.:

12/562196
Inventors:

Paul J. Zombo - Cocoa FL, US
Vinay Jonnalagadda - Orlando FL, US
Erwan Baleine - Orlando FL, US
Assignee:

Siemens Energy, Inc. - Orlando FL
International Classification:

H04N 7/18
US Classification:

348 82, 600474, 424 9, 424 34
Abstract:

An imaging system for on-line imaging of a component in a gas turbine engine. The imaging system includes a flexible imaging bundle formed by a plurality of optical elements. An imaging end of the optical elements images a component in a hot gas path of the engine during operation of the engine and a viewing end provides an image of the component at a location displaced from the hot gas path. The optical elements are surrounded by a flexible metal sheath that is permeable to air to provide cooling air the optical elements from an air source surrounding the flexible imaging bundle.

One-Dimensional Coherent Fiber Array For Inspecting Components In A Gas Turbine Engine
view source
US Patent:

8570505, Oct 29, 2013
Filed:

Mar 6, 2012
Appl. No.:

13/412920
Inventors:

Erwan Baleine - Orlando FL, US
Clifford Hatcher - Orlando FL, US
Assignee:

Siemens Energy, Inc. - Orlando FL
International Classification:

G01B 11/14
G01N 21/88
US Classification:

3562371, 356625
Abstract:

Inspecting a turbine includes positioning respective ends of a plurality of optical fibers within a high temperature region of the turbine wherein the respective first ends are aligned as a one-dimensional array. Energy emitted from an image area on a component of the turbine, is received at the ends of the optical fiber. The optical fibers convey the received energy to the other ends of the fibers that are located outside of the turbine. Outside the turbine an image of the respective other ends is captured, wherein the other ends are also aligned in a one-dimensional area. Additionally, for imaging a rotating component, a plurality of one-dimensional images of the other ends can be respectively captured at corresponding rotational positions of the component and used to create a two-dimensional image of the rotating component.

US Patent:

20070236698, Oct 11, 2007
Filed:

Apr 6, 2006
Appl. No.:

11/399632
Inventors:

Aristide Dogariu - Winter Springs FL, US
Erwan Baleine - Orlando FL, US
International Classification:

G01B 9/02
US Classification:

356479000
Abstract:

A light scattering sensing system and method. In one embodiment, the system includes a sample branch configured to collect light signals backscattered from scattering centers contained in a coherence volume of a medium under evaluation, the sample branch including a multi-mode optical waveguide. In one embodiment, the method includes radiating low-coherence light into a scattering medium using a multi-mode optical waveguide, and collecting light signals backscattered by the scattering centers and light reflected by an end surface of the multi-mode optical waveguide using the multi-mode optical waveguide.

US Patent:

20120200698, Aug 9, 2012
Filed:

Feb 9, 2011
Appl. No.:

13/023774
Inventors:

Erwan Baleine - Orlando FL, US
Danny M. Sheldon - Chuluota FL, US
International Classification:

H04N 7/18
US Classification:

348142, 348135
Abstract:

Method and system for calibrating a thermal radiance map of a turbine component in a combustion environment. At least one spot () of material is disposed on a surface of the component. An infrared (IR) imager () is arranged so that the spot is within a field of view of the imager to acquire imaging data of the spot. A processor () is configured to process the imaging data to generate a sequence of images as a temperature of the combustion environment is increased. A monitor () may be coupled to the processor to monitor the sequence of images of to determine an occurrence of a physical change of the spot as the temperature is increased. A calibration module () may be configured to assign a first temperature value to the surface of the turbine component when the occurrence of the physical change of the spot is determined.

US Patent:

20130088587, Apr 11, 2013
Filed:

Sep 14, 2012
Appl. No.:

13/617416
Inventors:

Gang Li - Princeton NJ, US
Yakup Genc - Dayton NJ, US
Erwan Baleine - Orlando FL, US
Dennis H. Lemieux - Casselberry FL, US
Assignee:

Siemens Corporation - Iselin NJ
International Classification:

H04N 5/33
US Classification:

348 82
Abstract:

Two adjacent objects with a gap between the objects rotate in a hot atmosphere with a temperature greater than 300 F in a gas turbine. Automatic and accurate contactless measurement of the gap is performed by taking images of the gap. An image, preferably an infra-red image is taken from the gap, a processor extracts the two edges from the image of the gap. The processor also determines a line through the pixels of an edge by applying a Hough transform on the pixels. The edges are substantially parallel. A line substantially perpendicular to the lines is also determined. Using the substantially parallel lines and the line substantially perpendicular to the substantially parallel lines the processor determines a width of the gap.

US Patent:

20130194379, Aug 1, 2013
Filed:

Jan 31, 2012
Appl. No.:

13/362308
Inventors:

Erwan Baleine - Orlando FL, US
Vinay Jonnalagadda - Orlando FL, US
International Classification:

H04N 7/00
G02B 3/00
H04N 7/18
G02B 3/02
US Classification:

348 36, 359708, 359664, 348 82, 348E07085, 348E05024
Abstract:

Optical camera systems for nondestructive internal inspection of online, operating power generation turbines, including gas turbine combustor and turbine sections that are at high operating temperatures in the range of over 600 C. (1112 F.) and which include combustion gas contaminants. The inspection system includes one or more aspheric lenses capable of withstanding continuous operating temperatures above 600 C. The aspheric lenses, alone or in combination with spherical lenses, establish a wider field of view, and require fewer lenses in combination than lens mounts incorporating only spherical lenses. A cooling system incorporated in the inspection system facilitates continuous operation and inhibits lens external surface fouling from combustion gasses.

US Patent:

20130194411, Aug 1, 2013
Filed:

Jan 31, 2012
Appl. No.:

13/362365
Inventors:

Erwan Baleine - Orlando FL, US
Vinay Jonnalagadda - Orlando FL, US
Michael Savard - Tucson AZ, US
International Classification:

H04N 7/18
G03B 17/00
US Classification:

348 82, 396529, 348E07085
Abstract:

Optical camera systems for nondestructive internal inspection of online, operating power generation turbines, including gas turbine combustor and turbine sections that are at high operating temperatures in the range of over 600 C. (1112 F.). The system includes one or more temperature and vibration-compensating lens systems in the optical tube mount. The lens is circumferentially retained within a lens mount, with a mounting ring in contact with only the lens axial face. A biasing element exerts axially oriented biasing force on the first lens face through the first mounting ring, allowing for mount flexure in response to operational turbine vibration and temperature changes. The lens mount is advantageously combined with aspheric lenses capable of withstanding continuous operating temperatures above 600 C. The aspheric lenses, alone or in combination with spherical lenses, establish a wider field of view, and require fewer lenses in combination than lens mounts incorporating only spherical lenses.
