Methods, systems, and apparatus are described for maintaining the interior cavities of pipes. In one aspect, a motorized apparatus includes a main body having a length extending along a longitudinal axis of the main body, where the main body comprises a first end and a second end opposite the first end. The motorized apparatus further includes at least one drive assembly coupled to at least one of the first end and the second end of the main body, where the at least one drive assembly comprises driven members that engage with an inner surface of the pipe and move the motorized apparatus through an interior cavity of the pipe. The motorized apparatus further includes a maintenance head movably coupled to the main body that moves along the length of the main body and rotates about the longitudinal axis of the main body, where the maintenance head comprises at least one tool configured to perform an action on the inner surface of the pipe.

Motorized apparatus for pipe inspection and repair

A system for use in maintaining a pipe includes a motorized apparatus including a body assembly and at least one maintenance device. The at least one maintenance device includes a sprayer, a heater, and an infrared sensor. The system includes at least one controller configured to apply the at least one coating material to the interior surface of the pipe at a work location using the sprayer, heat the interior surface of the pipe at the work location using the heater to begin a cure of the at least one coating material, generate one or more infrared images of the work location using the infrared sensor while using the heater to cure the at least one coating material, and perform a non-destructive evaluation (NDE) of the work location based on the one or more infrared images.

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.

Systems and methods for automatic detection of coating defects

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.

Systems and methods for detecting water in a fan case

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.

Inspection system and method

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.
