摘要： The disclosure describes assemblies, systems, and techniques for reinforcing complex geometries of pressure vessels using a pre-sintered preform (PSP) braze material that includes a low-melt powder and a high-melt powder. An example technique includes positioning a PSP reinforcement on a surface of a substrate. The technique includes heating the PSP reinforcement to soften or melt at least one constituent metal or alloy of the low-melt powder. During heating, the PSP reinforcement is configured to conform to a contour of the surface of the substrate. The technique also includes cooling the PSP reinforcement to define a reinforced component.

摘要： A technique for repairing a dual walled component comprising a spar comprising a plurality of pedestals and a coversheet attached to the plurality of pedestals may include removing a damaged portion of the coversheet from the dual walled component to expose a plurality of exposed pedestals and define a repair location and an adjacent coversheet portion. The technique also may include filling space between the plurality of exposed pedestals with a stop material. The stop material may define a surface substantially aligned with a pedestal-contacting surface of the adjacent coversheet portion. In some examples, the method additionally includes positioning a braze material on the surface of the stop material and attaching the braze material to the plurality of exposed pedestals and adjacent coversheet portion to form a repaired coversheet portion.

摘要： A gas turbine engine component may include an airfoil extending radially from a base to a blade tip, the airfoil including a pressure sidewall and a suction sidewall each extending between a leading edge and a trailing edge opposite the leading edge, an internal cooling circuit extending from the base to the blade tip; and a squealer tip. The squealer tip may include a first and a second squealer tip rail adjacent to the first squealer tip rail, and a squealer tip cap extending between the first and second squealer tip rails. The blade tip, the first and second squealer tip rails, and the squealer tip cap may define an internal squealer tip cooling channel. The blade tip may define a supply aperture that fluidly connect the internal cooling circuit and the internal squealer tip cooling channel.

摘要： The disclosure describes example techniques and assemblies for joining a first component and a second component. The techniques may include positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component, the joint region being coated with an adhesion resistant coating. The techniques may also include positioning a braze material in the joint region, heating the braze material to form an at least softened material, and cooling the at least softened material to form a mechanical interlock including the braze material in the joint region joining the first and second components. The braze material does not metallurgically bond to the joint surface.

摘要： The disclosure describes a method by a controller that includes: executing a model of a material based on a geometric template of the material defined by geometric parameters and at least one geometric constraint of the material; determining a value of an objective function based on differences between a three-dimensional representation of the material based on measurements of the material and the model of the material based on the geometric template of the material; and determining updated values of the geometric parameters of the geometric template. The method further includes iterating the executing the model of the material, the determining the value of the objective function, and the determining the updated values of the geometric parameters until a parameter associated with the objective function satisfies a criterion and, outputting the updated values of the geometric parameters associated with the objective function that satisfies the criterion.

摘要： A system may include at least one sensor, at least one machining device, and a computing device. The computing device may be operable to control the at least one sensor to inspect at least a portion of a coversheet of a dual walled component to generate dimensional surface data for the at least a portion of the coversheet and compare the dimensional surface data to surface model data. The comparison may indicate portions of the coversheet that include additional material. The computing device also may be operable to generate a compromise surface model based on the comparison between the dimensional surface data and the surface model data and control the at least one machining device to machine the dual walled component based on the compromise surface model to remove the additional material.

摘要： A system may include a source of dry ice, a thermal camera, and a computing device. The computing device may be configured to control the source of dry ice to cause dry ice to be introduced into an internal passage of a tested component. The tested component may include debris within the internal passage, and the dry ice may remove at least some of the debris from the internal passage. The computing device also may be configured to receive, from the thermal camera, thermographic image data representative of the thermal response of the tested component and output a representation based on the thermographic image data.
