Armor-piercing shell Iskra

As you know, the tank does not lose its significance in modern warfare and the basis of modern land forces is armored, represented by tanks and infantry combat vehicles. In order to increase the survivability of armored vehicles on the battlefield and defeat armor-piercing weapons of the enemy, are made in two ways:- increasing the thickness of the armor or using a complicated construction of armor (the armor uses a modular ceramic and composite armor of stainless steel). - installation on a tank with active protection against shaped-charge projectiles, anti-tank grenade launchers and guided anti-tank missiles. In this regard, overcoming the armor protection of these machines is a serious problem for anti-tank ammunition, which include submunitions, armor-piercing and cumulative shells, missiles and rocket-propelled grenades with kinetic and heat warheads, with a shock core. Use for hitting enemy tanks unguided and guided missiles are not always effective, as tanks equipped with an active protection, which destroys the rocket before approaching the tank, the rockets also have a high price. Shot for the tank or artillery guns are expendable, and should be very cheap, and should reliably hit enemy tanks and other armored vehicles at a considerable distance. At this distance, where anti-tank ammunition of the enemy will be powerless against the tank of the other side. If you increase the thickness of armor the weight of the tank is beginning to grow significantly, and because of this, the tank begins to lose its performance characteristics such as speed, range, handling, mobility, ground pressure, there is the impossibility of transporting it by road and rail due to the limitation of carrying capacity of bridges. If you use heat shells or missiles required to create a complex system of guidance and control, leading to an increase in the cost of the projectile. The use of shaped-charge projectiles does not lead to essential defeat of the tank, because the triggered active defense, under the armor of the tank, it destroys the projectile or missile at a distance from the tank. The cheapest and most reliable way to hit a tank is to use projectiles with the kinetic part. Projectiles with kinetic energy have a high armor penetration they differ from other anti-tank munitions to its high flight speed, low sensitivity to the effects of dynamic protection, the relative independence of the guidance system of the weapon from natural and man-made interference and small cost. As a material armor-piercing rod is used ceramics based on tungsten carbide (density of 15. 77 g/cc), and also metal alloys based on uranium (density of 19. 04 g/cc) or tungsten (density of 19. 1 g/cubic cm). Uranium alloys have advantages over tungsten due to the ablative of samazinasies and their penetration is higher by 15-20% compared with tungsten alloys, starting with speeds over 1600 m/sec.

However, uranium alloys have a significant drawback: when a nuclear strike in them neutron irradiation induced secondary radiation, it affects the crew. I also developed a rocket – assisted kinetic armor-piercing projectile. This projectile is designed to destroy ground, surface, air and armoured targets. Design and performance characteristics of the armor-piercing projectile does not have world analogues.

On armor-piercing shell obtained the invention patent of the Russian Federation no. 2588287 "Armor-piercing shell" from 03. 06. 2016 year. The design of the armor-piercing projectile is such that it is capable of hitting armored targets at considerable distances. Shooting such a projectile is of artillery systems. Kinetic armor-piercing projectile has a high flight speed, has the independence from artificial and natural interferences, insensitivity to the action of dynamic protection and has low cost. Armor-piercing shell is guaranteed to overcome the system of active protection of armored vehicles.

As a material for armor-piercing rod is used ceramics based on tungsten and metal alloys based on uranium or tungsten. Tungsten alloys have a significant advantage when using them as armor-piercing stud compared to ceramic, they are stronger in bending and compared to uranium alloys does not induce secondary radiation when a nuclear strike. However, they have the effect of ablative samazinasies begins to appear only at speeds exceeding 2000 m/sec. Therefore, for effective use of tungsten rod as a kinetic armor-piercing projectile must be given to the projectile velocity exceeding 2000 m/sec. The affecting factors of the shell are grains of armor flying in all directions in the tower space. After penetration of armor formed of small particles of tungsten dust, which ignite and provide an additional affecting factor. After breaking armor heavy metal dust (tungsten) hits in the airways crew and cause additional damaging effects.

Armor-piercing shell fired from barreled guns, giving the projectile an initial velocity more than 5 - 7 m (m - mach number), 700 – 2400 m/sec. To provide this initial velocity necessary to produce the casings for the patent for the invention № 2597934 "Multiple gun cartridge case to the projectile" from 25. 07. 2016. Armor-piercing projectile consists of several elements that allow to disperse the armor-piercing projectile with a speed 5 - 7 m, speed 7 - 9 m, 2380 – 3087 m/sec. And maintains this velocity throughout the trajectory. This drawing shows a side view of an armor-piercing projectile according to the patent for the invention № 2588287.

Ru/wps/wcm/connect/content_ru/ruв topic – information resources - public registries – the registry of inventions should dial the number of the patent for invention 2588287. Using this armor-piercing projectile after upgrading guns, tanks and artillery systems caliber 100 mm, 115 mm, 125 mm, 152 mm, 155 mm.

It is possible to push the obsolescence of military vehicles. Quick adoption of the munition into service will allow to increase the combat capability of the army sometime in the foreseeable future, and already today, required by the international situation. Main advantages of the proposed armor-piercing projectile is that:- always ready to fire without carrying out any routine maintenance. - possibility of long storage of the projectile without losing its fighting qualities. - the affecting factors of the shell are grains of armor flying in all directions in the tower space. After penetration of armor formed of small dust particles which burn and serve as an additional affecting factor. - after breaking armor heavy metal dust gets into the airways crew and cause additional damaging effects. - kinetic armor-piercing projectile has a high flight speed, independence from artificial and natural interferences, insensitivity to the action of dynamic protection and have low cost. - they can guarantee to overcome the system of active protection of armored vehicles. - in mass production they are easy to manufacture.

Armor-piercing shell is a consumable item and its price should be negligible compared to anti-tank or air defense missiles. One of the main objectives in war is to inflict irreparable war damage and significant economic. The cost of the armor-piercing projectile is minor, and it will hit the tank, for example, "Abrams" with a cost of $ 7. 0 million United States and other combat vehicles that have significant value. That is, the economic advantage of the proposed armor-piercing shells is undisputed. When firing from a tank gun or artillery systems armor-piercing projectile guaranteed destroyed enemy tanks on the course of visual observation, that is up to 30 000 m, and in the case of firing from a hill to 40 000 of such ammunition no army in the world. Test subcaliber projectile at 2,000 m/sec. Showed that his armor is 1000 mm homogeneous steel armor.

When shooting from artillery systems of the proposed armor-piercing projectile, with the angle of elevation of the barrel 45 range armor-piercing projectile will amount to usd 250. 0 – 300. 0 miles, the maximum altitude of the armor-piercing projectile will be 30,0 – 40,0 km. In the entire trajectory of the armor-piercing projectile speed does not change, even at maximum range it is capable of hitting armored vehicles. All these calculations are made from what materials armor-piercing projectile will be able to withstand the high temperature during combustion checkers solid fuel for about 100 seconds, however, it can be concluded that now in Russia there are materials that can withstand a burning time of solid fuel checkers more than 100 seconds, and that time is measured in tens of minutes. Therefore, the distance of firing armor-piercing projectile can be significantly increased. When firing armor-piercing shells at air targets, for example, shock drones, has the ability to destroy aircraft at a height of 40. 0 km and at this altitude it is now possible to destroy air targets only missiles, air defense, and not all systems.

It is clear that the cost of air defense missiles disproportionately more expensive armor-piercing projectile. Yet no such weapons neither we nor the enemy, and they are unlikely in the foreseeable time will be, which can counteract the kinetic data bronero.
