    摘要: There is disclosed a method of identifying non-conformance of a manufactured component, the method comprising: performing a volumetric scan to generate a 3-dimensional (3D) image of a volume of space containing the component, the 3D image comprising a plurality of voxels, each voxel representing a sub-volume within the volume of space and assigned a voxel value relating to properties of the material in the sub-volume; generating a component histogram giving the frequency of each voxel value within the volume of space; and comparing the component histogram to a template histogram, and identifying differences between the component histogram and the template histogram, and based on the comparison, determining whether there is a defect in the component.

    摘要: A thermal management system (100) for a gas turbine engine (10) includes a plurality of inlet and outlet vanes (104, 106) extending from a bypass inner wall (110) towards an outer cowl (120), a plurality of first removable shims (144), a plurality of second removable shims (146), and a third removable shim (148). Each first removable shim (144) extends between and engages the outer cowl (120) and a corresponding inlet vane (104). Each second removable shim (146) extends between and engages the outer cowl (120) and a corresponding outlet vane (106). The third removable shim (148) extends between and engages a heat exchanger (108) and the outer cowl (120). Each of the plurality of first removable shims (144), each of the plurality of second removable shims (146), and the third removable shim (148) is removable for positionally adjusting the outer cowl (120) relative to the bypass inner wall (110).
