Description

A composite anti-riot kinetic energy bomb with delayed boost function

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 boost function.

Background technique

As the mainstream anti-riot kinetic energy bombs in service, rubber bullets and sack bombs are gradually replaced by a new generation of composite anti-riot kinetic energy bombs because of their short effective range, poor strike accuracy and single effect. The composite anti-riot kinetic energy bullet is composed of two materials: soft warhead and hard warhead. Due to different impact speeds at different firing distances, different impact forces are generated and the warheads are forced to deform to different degrees to dissipate the impact energy. In the case of high-speed impact at close range, the warhead deforms greatly and dissipates more energy, which can reduce accidental damage to the target. In the case of long-distance low-speed impact, the warhead deforms less and dissipates less energy, which can convert a higher proportion of impact energy. Transfer to the target body to achieve the desired pain-inducing effect. Therefore, the composite anti-riot kinetic energy projectile solves to a certain extent the problems that the active anti-riot kinetic energy projectile is too powerful at close range and insufficient in long-distance efficiency, but to achieve the ideal energy consumption effect, there are very special requirements for the warhead material. It is difficult to solve the problem of excessive close-range power by optimizing the material of the warhead to obtain the ideal impact response characteristics of the warhead, because even if the warhead undergoes extreme compression deformation, due to the high exit velocity of the projectile, it is not enough to completely avoid the impact on the living target. Excessive damage, so it is necessary to further optimize the projectile structure design, so that the problem of "too much power at close range and insufficient performance at long distance" can be better solved, and at the same time, it can effectively solve the problem of the single end effect of the existing anti-riot kinetic energy projectile.

working principle:

First put the present invention into a suitable rifled anti-riot gun, lock the chamber, pull the trigger of the anti-riot gun, the firing pin hits the primer 1-3, the primer 1-3 ignites the propellant 1-5, and the propellant 1-5 burns violently , after reaching the predetermined pressure, the brass film sealing the axial fire-passing holes 1-6 and the oblique fire-passing holes 1-7 is broken, the gunpowder gas enters the low pressure chamber 1-8, and the propellant cartridges 1-1 and 1-1 are connected by ablation. After the hot melt adhesive of the main bomb body 2-1 reaches a predetermined pressure, it pushes the main bomb body 2-1 to separate from the propellant cartridge 1-1, and at the same time the gunpowder gas ignites the first extension tube 2-5 and the elastic belt 2-3 Squeeze into the female rifling of the anti-riot gun, and promote the bullet body assembly 2 to drive the guard plate assembly 3 and the warhead assembly 4 to spin. The plate assembly 3 is separated from the projectile assembly 2 and the warhead assembly 4 and falls off. After the delay time of 1 s, the first extension tube 2-5 fires at the rear, igniting the propellant 2-7 in the propellant chamber 2-6. , the propellant 2-7 is violently burned, and the gunpowder gas is ejected from the rear nozzle hole 2-8 at a high speed, realizing a boost to the projectile body assembly 2 and the warhead assembly 4, and the gunpowder gas simultaneously ignites the second extension pipe 2- 9. After the delay time of 1s, the second extension tube 2-9 fires at the rear, ignites the explosive expansion agent 2-10, and the explosive expansion agent 2-10 burns violently, generating instantaneous high pressure, forcing the projectile assembly 2 It is separated from the warhead assembly 4 and realizes the secondary boost to the warhead assembly 4.

The warhead body 4-1 is compressed and deformed greatly, and the upper striker 4-5-1 smashes the fragile cap of the high-pressure gas cylinder 4-4, and makes a loud blasting sound to achieve shock and deterrence to the target. The lower striker 4-5-3 smashes the upper end face of the stimulant load chamber 4-6. Due to the compression of the bullet body 4-1, the oblique nozzle 4-9 is temporarily closed, and the bullet assembly 4 rebounds. During the process, the warhead body 4-1 gradually returns to its original state, and under the action of high-pressure gas, the OC stimulating powder 4-7 is ejected at high speed from the oblique nozzle 4-9 to achieve the stimulation and dispersal of the front-side mass target of the present invention. Therefore, the present invention has the triple non-lethal effect of kinetic energy strike, detonation deterrence and stimulus dispersal at the end point.

When the present invention impacts a living target at close range, due to the small amount of propellants 1-5, the initial velocity of the projectile assembly 2 and the warhead assembly 4 are relatively low, and the warhead assembly 4 is deformed to dissipate part of the impact capacity. It is not easy to cause excessive damage to the target; due to the action of the first-stage delay booster mechanism, the projectile assembly 2 and the warhead assembly 4 have an acceleration process at medium firing distances, and the action of the second-stage delay booster mechanism makes the warhead assembly 4 There is a secondary acceleration process at long distance, so that the same kinetic energy strike effect as that at short distance can be obtained at medium and long distance. In addition, multiple non-lethal effects at the end point make the present invention better solve the existing anti-riot kinetic energy It has the practical problem of "too much power at close range and insufficient effectiveness at long range", and has good tactical flexibility.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and substitutions can be made in these embodiments without departing from the principle and spirit of the invention and modifications, the scope of the invention is defined by the appended claims and their equivalents.
