Description

The invention relates to expansive bullets for weapons with a drill "paradox" and can be used in hunting.

Known bullet type LSWC company WINCHESTER (USA), described in the article: "Anatomy of the bullet" from 06/04/2010 on pages 8, 9, available on the website www.saloncosmi.ru/info/articles/view/19.

This is a pistol bullet with a cylindrical leading part and a head part in the form of a truncated cone, lead, copper-plated, coated with grease. To retain the lubricant, annular grooves are applied to the drive unit by knurling. It should be noted that all lead bullets are coated with a special lubricating-preserving composition.

A disadvantage of the known bullet is that it is not intended for hunting.

The well-known bullet "Diabolo" described in the article: "Bullets for a smooth-bore" on the website www.ohot-prostory.com.ua/forum/viewtopic.php?f=16&t=:225&start=315. The Diabolo bullet was made by the Latvian engineer Gorbantes for firing smooth-bore hunting rifles at the Running Boar target and is a bullet with a head part in the form of a low rounded (conical?) Head with a serrated belt, with a leading part made up of a small conical transition to low cylinder, expanding to the rear of the cone, and a short cylindrical tail. A cone-shaped cavity is made inside the conical part of the leading part, into which sawdust is poured ..

The bullet gives a reliable and stable battle from shotguns with various muzzle constrictions, has great penetrating ability, good stopping effect.

The disadvantage of a bullet is the very complex shape of the hull.

Known "short" bullets 9 mm, described in the article: "Pressing bullets for PCP. The results of the use of the mold for bullets ”(p. 5 (upper drawing), 8) on the site forum.gims.ru/forummessage/30/546912.html.

The known bullet has a hemispherical head, a leading cylindrical part and a cylindrical girdle on the tail. In the leading part, an internal cavity is made in the form of a truncated cone expanding towards the tail.

Such bullets have a high speed, good accuracy, but the disadvantage is that they are good to use only at a distance of 60-70 m.

Known developed in France, an expansive bullet like THV, presented in the article "Expansive bullets" on the website http://fastinarksman.ru/400puli.htm. as well as Wikipedia.

A known bullet includes a cylindrical leading part, a head part having the shape of a hyperbolic cone from the outside (in the form of a pointed cone slightly curved inward by the lateral sides), five ring belts on the outer surface of the cylindrical part and an internal cavity symmetrically located along the longitudinal axis of the bullet in the form of a classic rocket from a cylinder with a conical apex and a slight conical extension at the bottom of the tail (see also Wikipedia.

A disadvantage of the known bullet is that, having a high speed and high stopping effect, it has low penetrating ability. Due to the special shape of the warhead when it hits the target body, the shock wave from it does not propagate forward, but to the sides; at the same time, a strongly pointed head increases armor penetration, improves the patency of armored fabrics by spreading the fibers without breaking, which does not allow its use in hunting. It is intended for special forces and is not for sale to civilians.

The closest in design to the claimed is the bullet "Ideal", presented in the article: Poshchastiev F.V. "Bullets for smooth-bore hunting rifles>" Ideal "bullet on the website http://www.hunter.ru/bullet/poschastiev/part23.htm and selected as a prototype.

Known bullet is made as follows.

The body of the bullet is formed by two cylinders - thicker and shorter in the head, longer and thinner in the tail. The cylinders are interconnected stepwise. In the head part of the bullet there are two leading belts above and below, the third is located on the conically expanded base of the bullet. In the center of the bullet there is a longitudinally extended conical channel in front, in which the blades are inclined to the longitudinal axis.

Its disadvantages lie in the complexity of the design, due to the presence of blades inside the bullet, and in unsatisfactory damaging properties, which is explained by the following circumstances.

The “Ideal” bullet comes into rotation from the blades located in its central channel, however, when moving in the barrel at supersonic speed, its turbine does not work, because an air congestion forms in the channel. Then, the flight speed decreases, but the blades, not having a sufficient area and set at too great an angle to its longitudinal axis, “break” from the air stream and do not rotate it. The bullet goes into rotation only after it leaves the barrel and passes a certain segment of the path during which it manages to deviate in one direction or another from the axis of the barrel channel, which ultimately reduces accuracy.

Leading belts and indentations between them on the body of the bullet create additional air resistance and do not contribute to the accuracy and slaughter of the bullet. In addition, it often warps at the muzzle of the trunk and sharply deviates in different directions from the direction to the target.

The objective is to simplify the design of the bullet and improve its striking properties.

The problem is solved in that the hunting expansive pool "Azart-Paradox", the body of which is formed by two cylindrically connected cylinders - thicker and shorter in the head, longer and thinner in the tail, outside in the head part there are two leading the belt, and another belt located on the conically expanded base of the bullet, while in the center of the bullet there is a through longitudinal conical channel according to the invention the body of the bullet is made of pure lead and has a copper coating on the outside, the connection of the cylinders of the bullet’s body is made in an oblique straight line with expansion at an obtuse angle to the warhead, in which the third lead belt is located in the middle between the two leading belts, while the central part of the bullet’s body, located between the last ring belt on the head and the tail of the bullet, the role of a bullet shock absorber with structurally incorporated deformation, the cone channel has an extension towards the end of the head part, which is made along a hyperbolic curve.

The inventive design of an expansive bullet makes it possible to obtain good striking properties due to the following distinguishing features.

The presence of three annular belts in the head part centers the bullet when it enters from the chamber into the barrel of the weapon. During the shot, the bullet tail along with the bullet shock absorber are deformed under the pressure of the powder gases to the size of the gun barrel and thereby shift the center of gravity of the bullet closer to the tail part relative to the geometric center, which, in turn, increases the bullet expansivity - provides significant deformation of the bullet head during hitting the target, i.e. enhances the damaging effect.

The energy of the powder gases spent on the deformation of the tail of the bullet - the bullet shock absorber, reduces the recoil of the weapon during firing, which has a positive effect on targeted shooting. All four ring belts, when the bullet passes through the “paradox,” give the bullet a rotational movement that stabilizes the trajectory of its flight and increases the accuracy of fire. Hyperbolic expansion of the internal cavity in the head part reduces the aerodynamic resistance of the bullet, increases its stability in flight, provides high expansiveness and, forming a sharp edge along the outer diameter of the head part, reduces the rebound; which also improves accuracy.

EFFECT: obtaining a bullet of a simpler design with good striking properties.

The inventive design of an expansive bullet makes it possible to obtain good striking properties due to the following distinguishing features.

Performing a bullet from pure lead maximizes its deformation when it enters the beast - it increases the bullet's expansivity; Due to the operation of the bullet shock absorber, which is designed for soft lead deformation, the recoil of the weapon in the barrel is reduced, which undoubtedly positively affects the ballistic characteristics of the shot and reduces the hunter's fatigue when shooting.

The presence of a copper coating on the outer surface of the bullet reduces the friction forces when the bullet moves in the barrel and positively affects the ballistic characteristics of the shot, as well as increases the shelf life and gives the product a salable appearance, protecting lead from oxidation.

The presence of three annular belts in the head part centers the bullet when it enters from the chamber into the barrel of the weapon. During the shot, the bullet tail along with the bullet shock absorber are deformed under the pressure of the powder gases, to the size of the barrel of the weapon and thereby shift the center of gravity of the bullet closer to the tail part relative to the geometric center, which, in turn, increases the expansivity of the bullet - provides significant deformation of the bullet head when hit by the target, i.e. enhances the damaging effect.

The energy of the powder gases spent on the deformation of the tail of the bullet - the bullet shock absorber, reduces the recoil of the weapon during firing, which has a positive effect on targeted shooting. All four ring belts, when the bullet passes through the “paradox,” give the bullet a rotational movement that stabilizes the trajectory of its flight and increases the accuracy of fire. Hyperbolic expansion of the internal cavity in the head part reduces the aerodynamic resistance of the bullet, increases its stability in flight, provides high expansiveness and, forming a sharp edge along the outer diameter of the head part, reduces the rebound; which also improves accuracy.

EFFECT: obtaining a bullet of a simpler design with good striking properties.

The inventive bullet has a novelty in comparison with the prototype, differing from it by such significant features as the performance of the body of the bullet made of pure lead with a copper coating, the connection of the cylinders of the body of the bullet to each other along an oblique straight line with expansion at an obtuse angle to the head, the presence in the middle of the head between two leading belts of the third leading belt, the use of the central part of the body of the bullet located between the last annular belt on the head part and the tail of the bullet as a bullet shock torus structurally planted deformation, the expansion channel to the conical end of the head portion of the hyperbolic curve, providing a plurality of achieving the desired result.

Although it is known that a bullet made of pure lead with a copper coating on the outside, such a bullet is not a hunting one. For the rest, the applicant is not aware of technical solutions that have the indicated distinguishing features, which together ensure the achievement of a given result, so he believes that the claimed bullet meets the criterion of "inventive step".

The inventive bullet can be widely used as a hunting expansive bullet, and therefore meets the criterion of "industrial applicability".

The invention is illustrated by drawings, which represent:

- figure 1 - General view of the bullet;

- figure 2 is a view of a bullet in a vertical section along the horizontal axis;

- figa and 3b is a view of a bullet in a vertical section along the horizontal axis before and after the shot;

- figure 4 - the aerodynamics of the internal cavity of the bullet according to the test results;

- figure 5 is a view of a bullet when hit in a tree (a) and in an animal (b).

The inventive bullet "Excitement" (figure 1) has a body of the head 1, leading 2 and tail 3 parts, made in the form of a composite cylinder with an internal cavity 4 along the longitudinal axis, having in the tail part the shape of a truncated cone, expanding to the head part in hyperbolic crooked. The hyperbolic curve (from the top point D of the hole in the head to the point of docking (point C) with the conical part of the hole) is made along a radius equal to ¼ the diameter of the gun barrel

The angle of inclination of the conical part of the inner cavity (from point C to point E in the tail) is 3 °.

On the outer surface of the hull there are four ring belts 5-8: three (5-7) of the same size in the head part 1 (0.2 mm more than the diameter of the gun barrel) and the fourth belt 8 in the tail part 3 ((less than the gun barrel diameter 1.0 mm), between which there is a bullet shock absorber 9.

The body of the bullet is made of pure lead and has a galvanic copper coating.

The inventive bullet due to the through hole of complex shape along the entire length of the bullet has a very large stopping effect, instantly paralyzing the beast due to great expansiveness, and provides good slaughter. When hit by a bullet, turning inside out, it doubles the diameter of the bullet hole (Fig. 4). Shooting through the reeds, reeds, and small bushes showed that the bullet cuts off these obstacles with a sharp outer edge, which reduces the rebound.

Compared with the prototype of the inventive bullet has a less complex design and higher damaging properties for use in hunting.
