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 warhead is larger in deformation and more in dissipation energy during short-distance high-speed impact, accidental injury to a target can be reduced, the warhead is smaller in deformation and less in dissipation energy during long-distance low-speed impact, and a higher proportion of impact energy can be transferred into the target body, so that an 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.
