“…The FSP in-flight velocity was measured by a double infrared velocity screen placed 2 m from the muzzle of the launcher. The distance was chosen to avoid interference with the muzzle flow that may trigger the counter of the velocity gates [23]. The system consisted of two sets of infrared gates.…”

This paper presents a study on the dynamic behavior of thin aluminum plates subjected to consecutive fragment impact and blast loading. To this end, two separate experimental setups are used. In the first setup, 2 mm thick aluminum plates EN-AW-1050A-H24 were subjected to the ballistic impact of fragment-simulating projectiles (FSPs). Experiments were carried out for FSP calibers of 7.62 mm and 12.7 mm considering both single impact and triple impacts with variations in the spacing of the impact locations. The out-of-plane displacement and in-plane strain fields were measured using digital image correlation (DIC) coupled to a pair of high-speed cameras in a stereoscopic setup. In the second setup, a subsequent blast loading was applied to the perforated plates using an explosive-driven shock tube (EDST). After the plates are perforated, the strain field around the holes depended on the caliber, the impact orientation of the FSP, and the distance between the impact locations. When the blast loading was applied, cracks tended to appear in areas of strain concentration between the perforated holes. It was found that the relative distance between the holes significantly influences the target’s response mode.

“…Sun et al [8][9][10][11][12][13] studied the shock wave and jet and secondary combustion processes in the muzzle fow feld by numerical simulation using detailed chemical reaction dynamics models. In the visualization of the muzzle fow feld, Moumen [14,15] combined Schlieren technology with high-speed cameras to realize quantitative visualization of trafc, and the results showed that this technique could visualize the density fow feld. In the measurement of muzzle shock wave pressure, Kong et al [16,17] used a piezoelectric sensor to measure the muzzle overpressure and established the distribution law of the muzzle overpressure.…”

A structured dynamic overlapping grid and a user-defined function are used to study the projectile launching process, and the hybrid Roe scheme is used to solve the flow field with strong shock wave. The launching process of a projectile with a muzzle decompression device is numerically simulated by using a three-dimensional transient model, and the flow field inside the muzzle decompression device and the development process of the muzzle flow field in the projectile launching process are discussed in detail. Compared with no device, the muzzle decompression device can effectively reduce the peak pressure around the muzzle; the numerical results are in agreement with the corresponding experimental values. The numerical investigation in this paper is helpful to understand the mechanism of pressure reduction of the device. It also provides a new way to reduce the muzzle pressure of aircraft gun.
