A method includes determining a perforation tunnel geometry of a perforation tunnel in a solid sample, the perforation tunnel created by activating a shaped charge in proximity to the solid sample. The method also includes performing a first flow test on the solid sample and creating an analog aperture having an aperture geometry in a solid sample analog of the solid sample, wherein the aperture geometry and the perforation tunnel geometry satisfies a similarity threshold. The method also includes performing a second flow test on the solid sample analog and determining a shaped charge effect based on a comparison between a second flow test result and a first flow test result.

A damage matrix generating device is proposed. The damage matrix may include a memory and a processor configured to control the memory. The processor may acquire warhead fragment data obtained by classifying mass and number of fragments scattering in given directions as a warhead is detonated, and target vulnerable area data obtained by classifying a vulnerable area according to an encounter relationship between a fragment and a target. The processor may also generate a virtual target based on an approach direction of the fragment to each of the grids, the grids dividing a ground plane. The processor may further generate a damage matrix by extracting encounter information of fragments to meet the virtual target as the fragments scatter in the given directions based on the warhead fragment data and calculating a damage probability for each ground location according to the encounter information based on the target vulnerable area data.

Provided is a new and improved method for examining the penetration of fragments in ballistic gelatin through the use of state-of-the art computed tomography (CT) equipment and analytical software. The inventive method can be used for fragment penetration testing as a key performance parameter (KPP). Ballistic gel containing multiple fragments are obtained, placed in a container, positioned in a CT chamber, and scanned. The scan is imported into a Volume graphics software program. A surface determination is made, which is used by one or more algorithms to isolate potential fragmentation within the gel block. The number of fragments, depth of penetration, and fragment mass are then calculated.

A headstamp marking method has the steps of fabricating a plurality of inventory cases, each of them being identical with a round surface, a bare metal head, and a body, and the cases being suitable for different caliber cartridges. The method then has trimming or necking the cases, selecting cases for manufacturing into cartridges, and inscribing, via a laser inscription device, the cases upon their heads. The laser inscription identifies at least the caliber of the cartridge and the number of the cases for manufacturing. The laser inscription device, while removing material of the head along its path, attains insufficient heat and thus avoids compromising the structure of the cartridges and igniting them. The laser inscription device aims and focuses its laser upon a common plane of a head while exhausting its heat through the material ejected from the head.

A testing system for testing a missile component having a sense axis includes a centrifuge, a support arm, an orientation assembly, and a controller. The centrifuge rotates the orientation assembly about a vertical axis in a substantially horizontal plane. The orientation assembly includes a first motor, a first gimbal, and a gimballed support. The first motor has a first rotatable shaft defining a first gimbal axis. The first gimbal is coupled with the first rotatable shaft to rotate about the first gimbal axis while the centrifuge rotates the orientation assembly about the vertical axis such that missile component is simultaneously rotated about both the vertical axis and the first gimbal axis to simulate a missile launch of the missile component. The gimballed support is coupled with the first gimbal for supporting the missile component such that the sense axis of the missile component is not parallel to the substantially horizontal plane. The orientation assembly may also include a second gimbal that is rotated about a second gimbals axis by a second motor.
