RU2570919C1 - Increase in armour-piercing efficiency of sub-calibre armour-piercer - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: claimed projectile is shaped to swept finned body made of the strong and high-density material, fins being made of traditional structural alloys. Claimed process consists in the application of the projectile body two armour-piercing parts. The projectile body second part is arranged in the charge case. The first parties arranged so that at depression of electric trigger the signal is transmitted via electric conductors to the trigger to ignite the powder charge. Powder gases act on the projectile second part to drive it. The projectile body second part thrust penetrates the charge case and projectile body cover. The projectile body second part thrust acts on the projectile body first part bore to eject the first body part from the projectile body. The projectile body is driven to muzzle velocity. The projectile body weight and length are increased at projectile exit from the barrel bore, the projectile body being stabilized by the fins.

Description

The invention relates to the field of military equipment, in particular to means for defeating highly protected samples of armored weapons with an armor-piercing projectile (hereinafter - BPS).

Known methods for increasing the efficiency of penetration of armor, in which inside the ballistic fairing in front of the warhead of the kinetic action with a conical front part, there is an armor-piercing tip made in the form of tubes interconnected by weakened jumpers (see the description of the patent for the invention of the Russian Federation No. 23518852007. State Unitary Enterprise "Instrument Design Bureau" Authors: Shipunov AG, Kuznetsov VM, Zhukov VP, Alekseev AN, Kozlov DV Open edition).

In addition, there is a known method of increasing the penetration efficiency of BPS armor, which is a swept feathered projectile, the body of which is made of durable and high-density material, and plumage from traditional structural alloys (see Armor-piercing feathered subcaliber projectile Link: https: //ru.wikipedia. org / wiki / Armor-piercing_openny_podkalibernoy_ shell. Open edition. Prototype).

The known method of increasing the efficiency of penetration of BPS armor allows to penetrate a relatively thick armor barrier at a considerable distance from the gun, to stabilize the body of the projectile during flight due to the action of aerodynamic forces, due to the plumage in the tail of the projectile body (similar to stabilization in flight of an arrow). However, this method has the following drawback - the effectiveness of projectile armor penetration is limited to a range of up to 2000 meters, at a greater distance from the target, armor penetration decreases, due to a decrease in the kinetic energy of the projectile body (speed), which reduces the probability of hitting the target as a whole.

The objective of the present invention is to increase the effective range of fire with an armor-piercing projectile, by increasing the mass and body length of the projectile and, as a result, its kinetic energy, increasing the penetration ability and the probability of hitting the target as a whole.

The technical solution of the proposed invention is the use of two parts of the projectile body as part of an armor-piercing projectile, located one in the charge body and the other in the shell of the shell so that when a powder charge ignites, the body part located in the charge body is pushed out by powder gases and is connected to the part body located in the shell of the shell, forming a single body of the shell, increasing its mass and length.

The technical result of the proposed invention is to increase the effective firing range, weight and body length of the projectile, as a result, its kinetic energy, increase the likelihood of hitting the target as a whole, avoid making structural changes to gun systems for firing this type of projectile, preserving the initial dimensions of the projectile and charge.

At the same time, a way to increase the efficiency of penetration of BPS armor is based on the fact that two parts of the shell body are used in its composition, one of which is in the charge body, and the other in the shell of the shell. When a powder charge ignites, a part of the body located in the charge body, under the influence of powder gases, enters the hole of the first part of the projectile body, pushing it out of the body of the projectile, increasing its mass and length. Subsequently, upon departure from the bore, the shell of the shell under the influence of strong air resistance is destroyed, and the body of the shell continues to move, stabilizing in flight due to the action of aerodynamic forces (plumage).

A method of increasing the efficiency of penetration of BPS armor, including a swept feathered projectile, the body of which is made of durable and high-density material, and plumage from traditional structural alloys, characterized in that two parts of the projectile body are used in the method, the second part of the projectile body is placed in the charge body, the first part of the body of the projectile is located in the shell of the projectile so that when you press the electric trigger, the signal is transmitted via electric wires to the trigger mechanism, the powder charge is ignited, the powder gases in act on the second part of the projectile body, set it in motion, pierce the charge body cover and the shell cover by focusing the second part of the projectile body, act by focusing the second part of the projectile body on the opening of the first part of the projectile body, push the first part of the projectile body out of the shell, attach to the body the initial velocity of the projectile, increase the mass and body length of the projectile upon departure from the barrel, stabilize the body of the projectile in flight due to plumage.

The invention is illustrated in FIG. 1, 2, which shows a device that ensures the operation of the method of increasing the efficiency of penetration of BPS armor, where: 1 - trigger 2 - the second part of the projectile body; 3 - emphasis of the second part of the body of the projectile; 4 - cover of the charge housing; 5 - shell cover; 6 - hole of the first part of the body of the projectile; 7 - emphasis of the first part of the body of the projectile; 8 - the first part of the body of the projectile; 9 - the body of the projectile; 10 - shell shell; 11 - trunk channel; 12 - electric wires; 13 - electric start; 14 - powder charge; 15 - plumage of the body of the projectile; 16 - charge housing; 17 - emphasis on the body of the projectile.

When firing from a gun, such as a tank gun, to penetrate a highly protected target, an armor-piercing sub-caliber projectile and a charge (separate loading) are used. This projectile consists of a body in which the body of the projectile is located, designed to hit the target when fired. The body of the projectile is hollow and has a plumage designed to stabilize during flight. In the body of the projectile is the first part of the body of the projectile, which extends forward and abuts against the body of the projectile, lengthening the body of the projectile, due to the impact on it of the second part of the body of the projectile located in the charge body. When you press the electric trigger, the signal is transmitted via electrical wires to the trigger mechanism, which acts on the powder charge located in the charge housing. Under the influence of powder gases, the second part of the projectile body, breaking through the cover of the charge casing and the cover of the projectile body, acts on the hole of the first part of the projectile body, pushing the first part of the projectile body out of the projectile body, increasing its length and weight. At the same time, the shell of the shell is given the initial speed. Upon departure from the bore, the shell of the shell under the influence of strong air resistance collapses, and the body of the shell with the first and second parts of the body of the shell inside it continues to move toward the target, stabilizing in flight due to the action of aerodynamic forces (available on the body of the plumage projectile).

An example of the method. When firing a cannon at an armored target, an armor-piercing piercing projectile and a charge are used. The projectile consists of a body 10, in which the body of the projectile 9 is located. In the body of the projectile 9 is the first part of the body of the projectile 8, which is advanced, due to the impact on it of the second part of the body of the projectile 2, located in the charge housing 16. When you press the electric trigger 13 the signal is transmitted via electric wires 12 to the trigger 1, which acts on the powder charge 14 located in the charge housing 16, which ignites and pushes the second part of the projectile body 2 out of the charge body 16, while the emphasis of the second part of the projectile body 3, breaking through the housing cover charge 4 and the cover of the shell of the projectile 5, acts on the hole of the first part of the body of the projectile 6, pushing the first part of the body of the projectile 8 out of the body of the projectile 9. The emphasis of the first part of the body of the projectile 7 abuts against the emphasis of the body of the projectile 17. At the same time, the shell of the projectile 10 is given the initial speed. When departing from the bore 11, the shell of the projectile 10 is destroyed, and the body of the projectile 9 and the first part of the body of the projectile 8 and the second part of the body of the projectile 2 inside it continues to move toward the target, stabilizing in flight due to the plumage of the body of the projectile 15.

The proposed method allows to increase the effective range of the armor-piercing projectile by increasing the mass and length of the body of the projectile, without increasing the initial dimensions of the projectile and charge and, as a result, its kinetic energy, to increase the penetration ability and the probability of hitting the target as a whole.
