Abstract: A system includes a laser configured to conduct a cleaning cycle that includes producing a laser beam capable of cleaning a faying surface of each of a plurality of nutplates, and conducting a first pass to clean each of the faying surfaces, wherein the laser is at a first position having a first angle relative to an axis orthogonal to the faying surfaces during the first pass. The system also includes a nutplate tray configured to hold the plurality of nutplates such that each faying surface is oriented such that the laser beam is capable of contacting each faying surface at least once during the cleaning cycle.

Abstract: A system includes a robotic arm, a rotisserie control linkage, and a computer system. The robotic arm includes a touch probe and laser head. The rotisserie control linkage is configured to couple to a transport cart. The computer system is communicatively coupled to the robotic arm and the rotisserie control linkage and is configured to control the system to probe, using the touch probe of the robotic arm, a transparent outer layer of an aircraft canopy located on the transport cart in order to determine surface measurements of the aircraft canopy. The computer system also controls the system to ablate, using a plurality of predetermined parameters and the laser head of the robotic arm, an interface layer located between the transparent outer layer and the aircraft canopy, wherein movements of the robotic arm during the ablation are based on the surface measurements.

Abstract: A system includes an abrasion component containing an abrasion pad configured to clean a faying surface of a nutplate and a shaft attached to the abrasion pad and configured to rotate the shaft and the abrasion pad during cleaning of the nutplate, which includes abrading the faying surface with the abrasion pad. The system further includes a base configured to attach to a pressure applicator, and the pressure applicator, which is configured to attach to the base, hold the nutplate such that the faying surface is capable of contacting the abrasion pad during the cleaning of the nutplate, and apply pressure to the nutplate such that the nutplate contacts the abrasion pad during the cleaning of the nutplate. Furthermore, the abrasion component is configured to rotate the abrasion pad within at least one of the base and the pressure applicator during the cleaning of the nutplate.

Abstract: A system includes a laser drive assembly and a computer system. The laser drive assembly includes a laser that emits a laser beam to clean an end of a tube, a first motor that changes an angle of the laser beam with respect to the end of the tube, a second motor that moves the laser laterally, and a third motor that rotates the laser drive assembly around the end of the tube. The computer system is configured to clean the end of the tube by operating the laser to emit the laser beam, adjusting the angle of the laser beam with respect to the end of the tube by operating the first motor, adjusting the distance between the laser and the end of the tube by operating the second motor, and rotating the laser drive assembly around the end of the tube by operating the third motor.
