    Abstract: A vacuum system and method for inspecting a workpiece that can include use of the vacuum system, where the vacuum system can include a housing defining at least a portion of a vacuum chamber, a piston within the housing that oscillates to vary a volume of the vacuum chamber, a first valve and a second valve in fluid communication with the vacuum chamber, and a hood in fluid communication with the second valve and the vacuum chamber. The vacuum system can include high-speed valves that enable vacuum system cycling and thus vacuum pressure cycling at a rapid frequency.

    Abstract: Systems and processes for enabling an off-site expert to interact with an on-site technician during repair of composite structure. The off-site expert can provide real-time guidance to an on-site technician before and during the performance of repair procedures to avoid errors. The off-site expert is also able to monitor the repair procedures in real time to verify that correct procedures are being employed. In particular, the systems and processes disclosed herein can provide direct visual guidance, feedback, and out-of-plan warnings for manual or automated scarfing and other operations during repair of composite structure. In some embodiments, the repair process combines optical three-dimensional surface measurement, illumination by at least one of visible, ultraviolet and infrared light, and digital light processing projection to provide step-by-step monitoring of the repair.

    Abstract: A method and system for an aerospace vehicle. A pulse of electromagnetic radiation is transmitted into the composite sandwich panel such that the composite sandwich panel is heated above an ambient temperature. An amount of infrared radiation generated in the composite sandwich panel is detected in response to transmitting the pulse of electromagnetic radiation into the composite sandwich panel using a time window selected to detect the amount of infrared radiation when the pulse of electromagnetic radiation heats the composite sandwich panel. The amount of infrared radiation detected indicates a level of moisture in the composite sandwich panel.

    Abstract: Provided is a method and system for dynamic shearographic inspection. The dynamic shearographic method allows nondestructive inspection of layered materials, in particular, those including a porous material. The method uses a load profile that increases and decreases the load, for example in a saw-tooth manner, without decreasing the load back down to the initial loading state, usually zero loading. Using the load profile in this manner constantly refreshes the reference speckle images to minimize background noise and allows defects to be distinguished from the noise.
