Description
Technical Field
The invention relates to the technical field of anti-riot bombs, in particular to a composite anti-riot kinetic energy bomb with a delay boosting function.
Background
Rubber bullets and cloth bag bullets are used as main stream explosion-proof kinetic energy bullets in service, and are gradually replaced by new generation composite explosion-proof kinetic energy bullets due to short effective range, poor striking precision and single action effect. The composite type anti-riot kinetic energy bullet is made of two materials, namely a soft bullet and a hard bullet, and different impact forces are generated due to different impact speeds under different shooting distances so that the bullets are forced to deform to different degrees to dissipate impact energy. The bullet is deformed greatly and the dissipated energy is more when the bullet is impacted at a high speed at a short distance, so that the accidental injury to a target can be reduced, the bullet is deformed less and the dissipated energy is less when the bullet is impacted at a low speed at a long distance, and a higher proportion of impact energy can be transferred into the target body, so that the expected pain-causing effect is achieved. Therefore, the composite anti-riot kinetic energy bomb solves the problems of overlarge close-range power and insufficient remote-range efficiency of the existing anti-riot kinetic energy bomb to a certain extent, but has very special requirements on the warhead material to achieve an ideal energy consumption effect, and the problem of overlarge close-range power cannot be solved essentially only by optimizing the warhead material to obtain an ideal warhead impact response characteristic.
