Aspects of the disclosure are directed to a probe for servicing a turbine blade of an engine. The probe includes hardware configured to couple to a fluid source, a stem, and an opening included in the stem, where the opening is oriented at a non-zero valued angle relative to a length of the stem. In some embodiments, a system includes a turbine blade of an engine, a machine that captures an image of the turbine blade, and a probe that includes a stem with an opening formed in the stem, where the opening is oriented at a non-zero valued angle relative to a length of the stem and removes debris from the turbine blade captured in the image based on an ejection of a pressurized fluid from the opening, where the debris is located on an interior surface of the turbine blade.

A method for scanning of an object in a scanning apparatus includes disposing the object and a complementary object on a support of the apparatus, so that the objects are positioned between an imaging beam emitting element and an imaging beam receiving element oppositely disposed to either side of the support. The support is rotatable relative to the emitting and receiving elements about an axis of rotation to allow creation of an image from projections each taken at a different relative angle. A volume of the complementary object is solid or filled with a filling material and the complementary object is configured to reduce the variation in imaging beam attenuation across the objects or the part to be scanned of the object at the multiple relative angles of rotation. The method includes operating the scanning apparatus at the multiple relative angles of rotation to produce an image of the object.

Aspects of the disclosure are directed to an analysis of a material of a component. A radiation source is activated to transmit radiation to the component. A beam pattern is obtained based on the component interfering with the radiation. The beam pattern is compared to a reference beam pattern. An anomaly is detected to exist in the material when the comparison indicates a deviation between the beam pattern and the reference beam pattern.

A method of characterizing a part including obtaining an X-ray tomography image of the part and then a step of correlating the image with a reference wherein the correlation step includes searching among a predefined set of X-ray tomography image transformations for a transformation that minimizes the difference between the image and the reference in order to characterize the inside of the part.

The present disclosure generally relates to methods for radiographic and computed tomography (CT) inspection of workpieces having increasingly complicated internal geometry. The disclosed methods are capable of distributing a contrast agent within the detailed internal geometry of, for example, an AM workpiece or precision cast turbine blade, followed by complete removal of the contrast agent and all residues thereof after inspection.

A method for scanning at least one component includes placing the at least one component inside a storage vessel; filling the storage vessel with a cryogenic material; cooling the at least one component; placing the storage vessel between an x-ray source and a detector of a CT scanner; generating, via the x-ray source, an x-ray cone beam after cooling of the component that passes through the storage vessel while the at least one component is disposed within the storage vessel; receiving the x-ray cone beam at the detector; and generating an x-ray image of the at least one component.

A phantom for use in quality control of tomographic images, the phantom including a cylindrical plate made of a uniform material having a density d1, with two cylinders being inserted in the plate, the cylinders being made out of uniform materials having different densities d2, d3, the density of one of the cylinders being greater than the density d1 of the plate, and the density of the other cylinder being less than the density d1 of the plate, and including a first series of pairs of holes of different diameters drilled in the plate, the axes of the holes of the first series being oriented axially relative to an axis of revolution of the plate, and the holes in a given pair being spaced apart from each other by a distance equal to their diameter.

A method of fabricating a reference blade for calibrating non-destructive inspection by tomography of real blades of similar shapes and dimensions, including making a three-dimensional blank out of resin, creating housings in the thickness of the blank at predetermined locations, and introducing in each of the housings a cylinder including an artificial defect or a real defect in order to obtain the reference blade.

A defect inspection system includes an X-ray generator that generates X-ray to be irradiated to a structure, and an X-ray detector that detects the X-ray generated by the X-ray generator and transmitted through the structure. In particular, the X-ray generator is configured to be moved by a first transporting means, and the X-ray detector is configured to be moved by a second transporting means. The system further includes a control unit configured to control and operate the first transporting means and the second transporting means.
