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.

A method of detecting a defect in a wind turbine blade uses a system that includes an X-ray generator, moved by a first transporting means, that generates X-ray to be irradiated to the wind turbine blade; an X-ray detector, moved by a second transporting means, that detects the X-ray generated by the X-ray generator and transmitted through the wind turbine blade; and a control unit. To detect a defect, the control unit divides virtually the wind turbine blade into a plurality of lengthwise sections based on a thickness profile thereof, receives a location of the X-ray generator, and controls output of the X-ray generator based on the location of the X-ray generator relative to the plurality of lengthwise sections. In particular, the output of the X-ray generator is decreased for a section among the plurality of lengthwise sections that is farther from a hub of the wind turbine blade.

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.

The invention relates to a method for verifying the positioning of a fibrous preform in a blade, the blade having been obtained by injecting a resin into a mould having the shape of a blade and in which a preform has been placed, the blade extending in an orthonormal blade frame of reference X, Y, Z, the blade comprising a blade root extending longitudinally along an axis X, a vane extending from the blade root along an axis Z, the blade having a thickness defined along an axis Y, the preform comprising glass tracers positioned at the surface of the preform, the centre of the tracers defining a neutral axis located at a height along the axis Z in the direction defined by the axis X, the method comprising the following steps: the acquisition (E31) of tomographic 2D projections of the blade using an imaging system comprising an X-ray source, each projection being acquired at a given orientation of the X-ray source with respect to the blade; the combining (E32, E32a, E32b) of the 2D projections in the direction of the axis Y so as to obtain a cumulative 2D image in the directions X and Z; the determining (E33), for each pixel column defined in the direction of the axis Z, of a greyscale profile; the processing (E34) of each of the profiles obtained so as to locate the position, in Z, of the neutral axis in the direction of the axis X.

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 of defining at least one scan parameter for an x-ray scan of a single crystal structure, the method comprising: determining a target orientation of the structure for the scan; and defining different non-zero levels of x-ray exposure for different parts of a scan area based on either or both of the target orientation and characteristics of the structure; and, defining the scan area so that substantially all x-rays of the scan are directed to the structure in the target orientation.

A method of detecting defects on a surface or interface of a part is provided. The method includes: providing data from an X-ray scan of the part; processing the scan data to obtain an original 3D or 2D model of a surface or interface topology of the part; and filtering the original 3D or 2D model of the surface or interface topology to identify deviations from the expected surface or interface topology of the part. The identified deviations may be produced by surface or interface defects on the part.

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.
