Abstract: A method for repairing a turbine engine includes determining a measure of a gap between the outer ends of a plurality of airfoils and an outer band is greater than a predetermined amount; and depositing an abradable material on the outer band in situ to reduce the measure of the gap between the outer ends of the plurality of airfoils and the outer band.

Abstract: A method is provided for repairing a turbine engine including a stage of vanes, the stage of vanes including a first vane having a first shroud and a second vane having a second shroud. The method includes: inspecting the stage of vanes in situ, wherein inspecting the stage of vanes in situ includes determining an actual gap width of a gap defined between the first shroud of the first vane and the second shroud of the second vane is greater than a predetermined threshold; and installing a shim in situ in the gap between the first shroud and the second shroud.

Abstract: A method includes obtaining a series of images of a rotating target object through multiple revolutions of the target object. The method includes grouping the images into multiple, different sets of images. The images in each of the different sets depict a common portion of the target object. At least some of the images in each set are obtained during a different revolution of the target object. The method further includes examining the images in at least a first set of the multiple sets of images using an artificial neural network for automated object-of-interest recognition by the artificial neural network.

Abstract: A system includes one or more processors configured to detect perimeter edges of one or more rotor blades of a turbine assembly as depicted in a series of image frames using boundary analysis performed on the image frames. The one or more processors are configured to identify a set of the image frames as key frames based on positional offsets between the perimeter edges that are detected in the image frames and a reference blade pose such that the key frames are able to be inspected for objects-of-interest without inspecting the image frames that are not the key frames.

Abstract: Methods are provided for repairing a surface of a component within a gas turbine engine. A first bladder and a second bladder can be installed (simultaneously or independently) within the gas turbine engine. The first bladder and the second bladder can then be inflated with an inflating fluid to form a first circumferential seal and a second circumferential seal to define an isolated area within the gas turbine engine. All the surfaces within the isolated area can then be coated with a masking layer. At least a portion of the masking layer can then be removed to expose a working area, and a coating can be formed on the working area.

Abstract: A method for additively manufacturing a component is provided. The method may include forming a surface on the top layer of the component, scanning the surface of the top layer of the component to determine if a defect is present in the surface, and if detected, correcting the defect within the surface. Scanning the surface of the top layer of the component to determine if a defect is present in the surface may be performed by obtaining data indicative of the surface of the top layer of the component by interrogating the surface of the top layer of the component with a scanning device, and comparing the data with a reference database to determine if an irregularity is present.

Abstract: A method for forming an in situ temporary barrier within a gas turbine engine is provided. The method can include installing a bladder within the gas turbine engine, wherein the bladder defines a bladder body, and inflating the bladder with an inflating fluid such that the bladder body forms a circumferential seal within the gas turbine engine. The bladder body can be positioned between a row of stator vanes and an annular array of rotating blades to form a circumferential seal therebetween. A second bladder may be positioned circumferentially within the gas turbine engine.

Abstract: The present disclosure is directed to a system and method for preventing damage to one or more components of the gas turbine engine during a repair procedure. The method includes locating one or more gaps of one or more components of the gas turbine engine in the vicinity of the defect. Further, the method includes filling the one or more gaps with a filler material so as to prevent arcing over the gaps during repair. Thus, the method also includes applying an electrical discharge to the defect.
