Abstract

The utility model discloses an anti-materiel armour penetration projectile for a sniper rifle. The anti-materiel armour penetration projectile comprises a bullet and a cartridge case. The bullet comprises three layers of a penetrator, an armour penetration layer and an armour from inside to outside, wherein the armour is divided into a front part and a rear part. The penetrator is made of homogeneous steel, and the armour penetration layer is made of depleted uranium materials. The front part of the armour is the cobalt oxide armour layer which is made of cobalt oxide ceramics. The rear part of the armour is the copper armour layer which is made of alloy copper. The anti-materiel armour penetration projectile for the sniper rifle can effectively penetrate the armour and attack the high-valve targets of a communication command system, a guidance system, a light armored car and a low-altitude skimming helicopter in the fight of special individual soldiers and weaken or destroy the fighting capacity.

Description

A kind of sniping gun is with anti-equipment high explosive anti-tank cartridge

Technical field

The utility model belongs to the national defense and military fields product.The anti-equipment high explosive anti-tank cartridge that particularly a kind of sniping gun is used.

Background technology

At present, a kind of individual soldier who develops in many countries snipes the high explosive anti-tank cartridge of application, uses cost in the hope of the weapon of minimum and obtains maximum tactical effect.This class high explosive anti-tank cartridge does not almost have any difference with general rifle bullet, diameter, length that its maximum characteristics are bullet and shell case are bigger, adopt heavy sniping gun emission, high pay-off targets such as special strike enemy's communication, guidance when extraordinary individual combat, because of it does not break away from the characteristics of traditional rifle bullet in design, so the broken first blow performance to some high pay-off targets is not more satisfactory, can not effectively weaken or damage its fighting capacity.

Summary of the invention

The utility model aims to provide a kind of anti-equipment high explosive anti-tank cartridge that sniper rifle uses that is used for, and hits the high pay-off targets such as helicopter of traffic guidance system, guidance system, LAV and low latitude line traversing specially.

The utility model comprises bullet and shell case two parts.Bullet is divided into three layers from inside to outside, is respectively bullet core, broken first layer, wears armor.Wherein, wear armor and be divided into before and after two parts.Playing core makes for the homogeneous steel; Broken first layer is the depleted uranium material; The front portion of wearing armor is divided into the cobalt oxide layer of wearing armor, and is made by the cobalt oxide pottery, and the rear portion of wearing armor is divided into the copper layer of wearing armor, and is made by alloyed copper.

The bullet core of being made by the homogeneous steel can make bullet can stablize the broken first ability of bullet after hitting the mark, and is that plumbous matter material is made unlike the bullet core of the bullet that has, and can't stand brokenly that because of holding first power is out of shape, and will weaken the broken first power of bullet like this.

Broken first layer front is that pointed, the pointed root and the main body section Position Design of broken first layer have been processed the broken first mouth of a circle.

Bullet diameter of the present utility model is 14.5mm, and it is consistent that the diameter of shell case and length and homemade individual soldier's special type are sniped the diameter, the length that play shell case, also is complementary with the heavy sniping gun of homemade 14.5mm.

The utility model sniping gun with anti-equipment high explosive anti-tank cartridge kinetic energy theory is: after bullet hits the mark, the forward part cobalt oxide of wearing armor is worn armor layer because hardness reaches 1800HV/10Mpa, fracture toughness is 6-9Mpa/m, so cobalt oxide wear armor the layer can be effectively to breaking first, collapse diffusing because of breaking the first impulsive force target being broken in the first process cobalt oxide layer of wearing armor, the interior broken first layer of bullet this moment has just come out, because broken first layer is made by the depleted uranium material, its hardness is 2200HV/10Mpa, flexural strength is 1200Mpa, so broken first layer is in continuing the broken first process of follow-up, the broken first mouth of its front design will carry out the high-speed screw cutting to broken Leptostraca mark, and with the broken first impulsive force of bullet to around radiation, make the wound at the broken first position of target tear expansion more, target is caused bigger damage.

Fig. 4 is the schematic top plan view of broken first layer in the utility model bullet.

Among the figure: the 1-bullet; The 2-shell case; The 3-cobalt oxide layer of wearing armor; The copper layer of wearing armor of 4-; 5-breaks the first layer; 6-bullet core; 7-breaks the first mouth.

The specific embodiment

The utility model is described in further detail below in conjunction with Figure of description:

The utility model shown in Figure 1 is made up of bullet 1 and shell case 2.The diameter of bullet 1 is 14.5mm, and the diameter of shell case 2 and length will to snipe the diameter, the length that play shell case consistent with homemade individual soldier's special type, also is complementary with the heavy sniping gun of homemade 14.5mm.

Bullet 1 shown in Figure 2 by cobalt oxide wear armor layer 3, the copper layer 4 of wearing armor, broken first layer 5, play core 6 and constitute.The root that broken first layer 5 front are pointed and the main body section Position Design of broken first layer 5 the broken first mouth 7 of a circle, the cobalt oxide layer 3 of wearing armor is estimated pottery by oxidation and is made, the copper layer 4 of wearing armor is made by alloyed copper, and broken first layer 5 is made by a minute depleted uranium material, plays core 6 and is made by the homogeneous steel.

Wherein, the Main physical performance indications of cobalt oxide pottery are: hardness 1800HV/10Mpa, and fracture toughness is 6-9Mpa/m; The Main physical performance indications of depleted uranium armor are: hardness is 2200HV/10Mpa, and flexural strength is 1200Mpa.

After sniping gun hits the mark with anti-equipment high explosive anti-tank cartridge, the cobalt oxide of bullet 1 layer of wearing armor 3 can break first to target effectively, the cobalt oxide layer 3 of wearing armor collapses diffusing because of breaking the first impulsive force in the process of broken first, this moment, bullet 1 interior broken first layer 5 just came out, since the root at the pointed position of broken first layer 5 and the main body section Position Design of broken first layer 5 the broken first mouth 7 of a circle, so broken first layer 5 breaks first mouth 7 in continuing the broken first process of follow-up because the spiral effect of inertia carries out the high-speed screw cutting to broken Leptostraca mark, and with the broken first impulsive force of bullet 1 to around radiation, make the wound at the broken first position of target tear expansion more, target is caused bigger damage and strike.

In sum, the utility model in special operations, the high pay-off targets such as helicopter of traffic guidance system, guidance system, LAV and low latitude line traversing are had effectively hit, the damage ability.
