Abstract: Systems and methods for electromagnetically controlling the muzzle velocity of a conventional gun using a coil gun on a barrel extension. This method can also provide an electromagnetically induced increase to muzzle velocity beyond that capable by conventional explosives. With higher muzzle velocity, the weapons will have longer range, higher penetrating power and stand-off distances. A section of coil gun can also be used to center the projectile in the barrel to control the exit trajectory. Using a coil gun to control muzzle velocity and center the projectile can be a retrofit to existing weapons that would greatly increase their down-range accuracy.

Abstract: The disclosed systems and methods relate to inspecting uncured fiber-reinforced composite components by non-contact 3D measurements of the component using 3D digital image correlation with patterned illumination. Systems comprise a light projector configured to project a light pattern onto a form, a digital camera configured to image the light pattern, and may comprise and/or be associated with an AFP machine that is configured to lay uncured composite on the form. Methods comprise projecting a light pattern onto a form, acquiring a baseline 3D profile of the form by imaging the light pattern on the form, laying an uncured fiber piece onto the form, projecting the light pattern onto the uncured fiber piece, acquiring a test 3D profile of the fiber piece by imaging the light pattern on the uncured fiber piece, and computing a thickness difference between the test 3D profile and the baseline 3D profile.

Abstract: An optical monitoring method and system for monitoring a component may include an imaging sub-system including at least one camera having a first optical path and a second optical path. The first and second optical paths may include respective first and second direct lines of sight. A region of interest of the component is outside of at least one the first and second direct lines of sight. The region of interest may include at least one image correlation feature. A reflector sub-system alters the first and second optical paths so that the region of interest is within the first and second optical paths.

Abstract: A method and system for a light source detection system, comprising an aircraft carrying at least one camera. The system includes a database for storing information about the aircraft's motion, direction, and position and ground location information, such as the onboard navigation system database or an remotely accessible database. The system also includes a processor that accesses the database and is connected to the camera. The processor uses image analysis and processing techniques to determine the ground location corresponding to the light source from an image of that light captured by the camera. It determines the path traveled by that light and estimates its location as being a pre-selected distance vertically above the ground along the path traveled by the light to the aircraft when the image of the light was captured.

Abstract: A method and system for installing rivets is disclosed. The method involves positioning a rivet through a structure to be joined. The method further involves positioning a first rivet gun on a first side of the rivet and positioning a second rivet gun on a second side of the rivet. The method also involves synchronizing firing of the first and second rivet guns, so as to cancel forces that otherwise would propagate into the structure during installation of the rivet.

Abstract: A method for analyzing a bondline in a structure is provided. The method includes obtaining, from a first side of the structure, by at least one computing device, at least one first internal image of the structure that includes at least a first pattern associated with the bondline, wherein the structure is in a pre-loaded state and obtaining, from the first side of the structure, by the at least one computing device, at least one second internal image of the structure that includes at least the first pattern, wherein the structure is in a loaded state. Additionally, the method includes comparing, by the at least one computing device, the at least one first internal image with the at least one second internal image, and determining, by the at least one computing device, at least one stress and/or strain-related property of the bondline based on the comparison.

Abstract: A method and apparatus for digital image correlation. A camera system is used to obtain larger scale images of a larger scale dot pattern on a surface of a workpiece and smaller scale images of a smaller scale dot pattern on the surface of the same workpiece. The smaller scale dot pattern forms a larger dot in the larger scale dot pattern in the larger scale images. The larger scale images and the smaller scale images may be used to determine a measurement of the workpiece.
