Abstract: Aiming at the high probability of injury and death in the application of anti-riot kinetic energy projectiles, a new low-kinetic energy fragile projectile is designed based on the existing non-lethal weapon launch vehicle. The fragile projectile has the characteristics of reliable shell crushing and powder dispersion energy release. Through the shooting test of the low kinetic energy fragile bomb on the dummy target and the gelatin target, the impact dynamic response of the two targets is obtained. In the dummy target test, the new fragile bomb has a high stable fragmentation rate and an obvious kinetic energy slow release effect. The calculated damage assessment indicators of different parts of the dummy are all within the safety threshold, indicating that the fragile bomb has high safety for personnel to strike; In the shooting test of gelatin target, the peak value of internal pressure of brittle projectile and rubber projectile with the same mass is about one order of magnitude different under the condition of similar landing velocity. The test results show that the new low-kinetic energy fragile ammunition can greatly and reliably consume the overall impact kinetic energy of the projectile through the impact crushing of the warhead shell and the flying of powder inside the warhead, which significantly reduces the damage power of non-lethal kinetic energy ammunition, and provides technical support for improving the safety of anti-riot kinetic energy ammunition.
