RU207328U1 - An armor-piercing sub-caliber projectile with an energy impulse to the sub-caliber core with an explosive in a blind channel of the pallet - Google Patents

Abstract

The utility model relates to weapons, namely to ammunition, and can be used to engage armored targets and shelters. An armor-piercing sub-caliber projectile has an outer shell made of soft material in contact with the barrel bore. The projectile includes a high-strength alloy sub-caliber core placed inside the shell and a pallet made of a softer material. An explosive is placed inside the pallet between the sub-caliber core and the blind channel of the pallet with a gap with the sub-caliber core, which does not fire spontaneously when the projectile is fired and is triggered only when the sub-caliber core hits it at the moment the projectile meets an obstacle. In the rear part of the projectile, there is a composition that lubricates the barrel bore through the nozzle holes when fired and has low carbon formation on the barrel bore. The technical result consists in increasing the striking properties and penetration of obstacles. 1 ill.

Description

The utility model relates to ammunition and can be used to engage lightly armored targets.

Various designs of sub-caliber bullets and projectiles are known.

These are bullets for hunting ammunition (patents for utility models RU 97190U1, RU179490U1), bullets for military ammunition (patents for inventions RU2502940U1, RU2498203U1). In all of these designs, an additional part of the bullet is used to stabilize the striking part of the bullet in flight or to give the striking part more energy from the additional part when the bullet meets an obstacle. All of these designs of ammunition use the kinetic energy of the additional part to increase the damaging properties, the penetration of obstacles by a high-strength sub-caliber core. There are also known special devices that use the energy of a squib shot for driving in dowels-nails.

To increase the striking properties and penetration of obstacles, a design of a sub-caliber projectile is proposed with an explosive charge inside an additional part of the projectile with the possibility of transferring the explosion energy of the sub-caliber part of the projectile, while the sub-caliber part receives additional kinetic energy from the explosion and an additional part of the projectile.

The proposed projectile has a soft shell 1 in contact with the rifling of the barrel of the weapon. Inside the shell 1 there is a high-strength sub-caliber core 2 and an additional part - a pallet 3 with an axial blind channel 4 with a conical bottom, which concentrates the energy impulse from the explosive in the direction of the core, inside the channel 4 there is a lower part 5 of the sub-caliber core 2. Inside the channel 4 there is an explosive 6, triggered by a sharp blow, but not triggered when the projectile is fired. A safety gap is made between the end surface of the lower part 5 of the sub-caliber core 2 and the surface of the explosive 6. the groove 10 for fixing the projectile in the sleeve has nozzle holes 11 for injecting the composition 8 into the barrel bore to lubricate the rifling when fired.

At the moment of firing, the projectile leaves the sleeve, nozzle holes 11 open, composition 8 melts under the action of the temperature of the powder gases, the plug 9, under the action of the pressure of the powder gases, squeezes the liquefied composition 8 through the nozzle holes 11 into the barrel bore, through the gap between the projectile and the surface of the barrel bore between the grooves, the composition leads the projectile with powder gases, lubricates the barrel and the grooves in front of the projectile.

When fired, a slight deformation of the shell 1 of the projectile and pallet 3 occurs, the sub-caliber core 2 is displaced, but due to the safety gap 7 does not reach the explosive 6. When the projectile hits an obstacle, significant deformation of the shell 1 and pallet 3 occurs, the sub-caliber core 2 strikes the explosive 6, during the explosion, the sub-caliber core 2 receives additional energy from the explosion and the reverse acceleration of the pallet 3, the large kinetic energy of the sub-caliber core 2 significantly increases its damaging properties. Lubrication of the barrel bore during firing significantly reduces its wear and increases the initial velocity of the projectile.
