Abstract: A detection system configured to detect water in a fan case includes a heater, a monitoring camera, and a computing device. The heater is configured to apply heat to the fan case. Any water within the fan case generates a local transient thermal gradient in response to the applied heat. The monitoring camera is positioned proximate the fan case and configured to acquire a plurality of images of the heated fan case. The computing device is configured to: receive the plurality of images from the monitoring camera and analyze the plurality of images to detect the water in the fan case.

Abstract: An inspection system includes one or more imaging devices and one or more processors. The imaging devices generate a first set of images of a work piece at a first position relative to the work piece and a second set of images of the work piece at a second position relative to the work piece. At least some of the images in the first and second sets are acquired using different light settings. The processors analyze the first set of images to generate a first prediction image associated with the first position, and analyze the second set of images to generate a second prediction image associated with the second position. The first and second prediction images include respective candidate regions. The processors merge the first and second prediction images to detect at least one predicted defect in the work piece depicted in at least one of the candidate regions.

Abstract: An inspection system includes a light source, an imaging device, and one or more processors. The light source is configured to direct an illumination light having a controlled light characteristic towards a surface of a thermal barrier coating of a work piece. The imaging device is configured to capture image data of the surface of the thermal barrier coating by monitoring the illumination light reflected off the surface. The one or more processors are operably connected to the imaging device and configured to analyze the image data of the surface by comparing the image data to reference image data depicting a first designated microstructure. The first designated microstructure has an associated coating quality value. The one or more processors are configured to determine that the thermal barrier coating of the work piece has the first designated microstructure based on the analysis.

Abstract: A method for forming a mold for casting a titanium-containing article, the method including combining calcium aluminate with a liquid to produce an initial slurry of calcium aluminate and adding oxide particles into the initial slurry to create a final slurry. The method further includes introducing the final slurry into a mold cavity that contains a fugitive pattern and allowing the final slurry to cure in the mold cavity to form a mold of a titanium-containing article.

Abstract: An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.
