Measurement & Control
Fast and accurate
turbine blade inspection
Extremely fast and accurate CT based inspection
The new GE blade|line X-ray CT inspection and measurement system
enables fast, high quality imaging of complex, advanced technology
engine components such as high pressure turbine blades.

As aircraft engine performance requirements become
more stringent, turbine blade cooling schemes advance

challenges require a shift from previous methods of

ThelineprolesacquiredbyGE’sJupiterlineardetectorarray,

contain information on the position of the external and internal
bladesurfacesaswellasinternalcastingaws.Thisdataisused
to reconstruct the tomographic slice image.
By vertically shifting the sample through the fan beam, the
required number of CT slices is compiled and analyzed at the
GERhythmReviewWorkstation.

Inspection Technologies.
When compared with conventional cone beam CT, highly collimated fan beam CT oers improved resolution, as well as, a higher
quality CT slice result, due to the reduction of image artifacts caused by scattered radiation.

The Power of Rhythm / DICONDE
All the 2D and CT slice images acquired by the blade|line system
are automatically created in the non-proprietary and reliable
DICONDE(DigitalImagingandCommunicationinNDE)format.
DICONDE incorporates many features that are NDE-focused
describing all of the necessary syntax, attributes and data
elements. Users can evaluate, archive, transmit and receive
acquired data. The GE blade|line CT system uses the
well-establishedGERhythmSoftwareplatformforimage
analysis and data management.
