RU2540220C2 - Device for shell (bullet) to move with rotation - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: device for shell to move with rotation in smooth-bore gun is a portion of gun barrel or an attachment to barrel with side slots arranged at an angle to the barrel channel. Powder gases pushing a shell along the barrel channel and reaching the device due to the slots come out from these slots generating at the same time side thrust for the shell. The shell makes axial rotational movement.

EFFECT: simplifying production of gun barrels, improving barrels operation life, improving accuracy and range of fire, higher penetration capability of a shell or a bullet.

Description

The invention relates to military equipment and can be used in smoothbore small arms, pneumatic weapons, artillery, and other devices where throwing a ballistic projectile under gas pressure is required.

A device for twisting a projectile or bullet, called "rifling" in the channel of the gun barrel to give the projectile or bullet rotational motion, which ensures its stability on the trajectory, range and accuracy of fire.

The disadvantage of the prototype is the complexity of the manufacture of rifling, as well as the fact that a bullet or projectile, passing rifling, experiences significant resistance to friction, which negatively affects the longevity of the barrel, the accuracy of the battle, and also requires an increase in powder weight. In addition, the bullet, having passed the bore, is deformed at the outset due to interaction with rifling, which also negatively affects the ballistic characteristics.

The invention solves the following problems.

1. The ability to give the projectile or bullet rotational motion without using rifling.

2. A significant simplification of the production of gun barrels.

3. Increasing accuracy and firing range.

4. Reducing the powder charge, which should have a positive effect on saving the production of cartridges, reducing the recoil of weapons during firing, increasing the life of parts and mechanisms of weapons, barrel life.

5. The possibility of using all-metal shells or bullets of brass, copper, steel, which will positively affect the penetration ability.

The technical result obtained from the invention is to give the projectile or bullet rotational motion in smooth-bore weapons.

The specified technical result is achieved by the fact that to impart a rotational motion to the projectile or bullet, the pressure of powder gases or other gases is used by means of special side slots in the device. Under the term “other gases” the author implies any other gases through the pressure of which a projectile or bullet is thrown.

The claimed invention can be applied in small arms, pneumatic weapons, artillery and other devices where throwing a ballistic projectile under gas pressure is required. In addition, this invention can be applied in existing rifled weapons to increase the rotational speed of the projectile or bullet.

Technical solutions with features that distinguish the claimed solution from the prototype are unknown. This suggests that the claimed solution is new and has an inventive step.

The accompanying invention is illustrated by drawings, where figure 1 shows a cross section of a device. Figure 2 shows the cross section of the device and the direction of rotation of the projectile or bullet, as well as the direction of motion of the powder or other gases, where: 1 - the device itself; 2 - a shell or a bullet; 3 - the direction of motion of the powder or other gases; 4 - direction of rotation of the projectile or bullet. Figure 3 shows the device in perspective.

A device for imparting rotational movement to a projectile or a bullet is a section of the barrel or a nozzle to the barrel, having side slots located at an angle to the barrel channel.

The device operates as follows.

Powder or other gases, pushing a projectile or bullet through the bore and reaching the device, due to the presence of side slots in the device, exit these slots, creating simultaneously a lateral rotational thrust for the projectile or bullet, while the projectile or bullet makes an axial rotational movement.

Using the term “slots”, the author was guided by a technical dictionary, namely: “Slots are holes that are usually oblong in shape”. Since the term “usually” is not exclusive, the author suggests that these holes may have a different shape.

Claims (1)

A device for imparting rotational movement to the projectile or bullet, characterized in that the axial rotation of the projectile or bullet is achieved by the pressure of the powder gases by means of side slots in the barrel section or the barrel nozzle, while these slots are located at an angle to the barrel channel.
