Description

Composite non-lethal kinetic energy projectile with multi-stage buckling structure

Technical field

The present invention relates to the technical field of non-lethal ammunition, specifically a composite non-lethal kinetic energy ammunition with a multi-stage buckling structure.

Background technique

From rubber bullets, stick bullets, rubber bullets, bag bullets to attenuated energy kinetic energy bullets, non-lethal kinetic energy bullets have developed all the way. Their structures are constantly changing, their styles are increasing, and their safety is constantly improving. The purpose of continuous optimization and upgrading is to Effectively subdue the target while ensuring safety.

The latest generation of attenuated energy kinetic energy bullets, based on composite non-lethal kinetic energy bullets, consists of two components: a composite soft warhead and a hard projectile body. It is launched through a rifled anti-riot gun and achieves high-precision point strikes through projectile spin. The impact energy is dissipated through the deformation of the warhead itself and the shear failure or buckling deformation mechanism designed inside the projectile. During close range and high-speed impact, the deformation and damage are larger and more energy is consumed, which can reduce the probability of excessive injury; but the gyro is stable When the projectile is disturbed by unstable factors, it may roll in the air, which will inevitably lead to the hard projectile directly hitting the living target, causing serious injuries. Therefore, it is necessary to develop a type of non-lethal kinetic energy projectile. It not only has the advantages of traditional composite non-lethal kinetic energy projectiles with high accuracy and relatively controllable energy, but also does not cause the potential danger of hard projectiles directly injuring the target.
