摘要： Systems and methods for automatic detection of defects in a coating of a component are provided. In one aspect, a coating inspection system is provided. The coating inspection system includes a heating element operable to impart heat to the component as it traverses relative thereto. An imaging device of the system captures images of the component as the heating element traverses relative to the component and applies heat thereto. The images indicate the transient thermal response of the component. The system can generate a single observation image using the captured images. The system can detect and analyze defects using the generated single observation image.

摘要： A method for inspecting a component is presented. The method includes inducing, by an inductive coil, an electrical current flow into the component. Further, the method includes capturing, by an infrared (IR) camera, at least a first set of frames and a second set of frames corresponding to the component, wherein the first set of frames is captured at a first time interval and a second set of frames is captured at a second time interval. Also, the method includes constructing, by a processing unit, a thermal image based on at least the first set of frames and the second set of frames corresponding to the component. Furthermore, the method includes determining presence of a thermal signature in the thermal image, wherein the thermal signature is representative of a defect in the component.

摘要： 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.

摘要： An inspection system includes one or more processors and an infrared (IR) camera operably coupled to the one or more processors. The one or more processors control a microwave transmitter to sequentially emit microwaves having different frequencies within a designated frequency range into an object during a first sweep. The IR camera generates thermal image data of the object after the object is heated by each of the different frequencies of microwaves. The one or more processors analyze the thermal image data and determine a selected frequency within the designated frequency range that provides greater heating of the object than one or more other frequencies in the designated frequency range. The one or more processors also analyze select thermal image data of the object, responsive to heating of the object by the selected frequency of microwaves, to detect an element in the object.

摘要： A coating analysis system and method inductively heat a component having a coating. Optionally, the component is heated while a cooling fluid flows through cooling holes extending through the component and the coating. The system and method measure rates of infrared radiation emission from the component and the coating at different locations on the component and the coating. The system and method determining bond qualities (e.g., tensile strengths of bonds) between the coating and the component at the different locations based on the rates of infrared radiation emission that are measured.
