Description

The invention relates to the field of engineering and is intended for throwing shells and can be used in various industries, as well as for the design and manufacturing technology of trunks of various types.

The well-known product barrel firearms (Patent RU No. 2150063 from 03.25.1999 MPK8 F41A), has a fundamentally similar design with weapons from a pistol to a gun with specific tabular performance characteristics and allows you to perform tasks at specific ranges with a certain performance.

The disadvantage of existing barrel systems is a significant limitation when working on closed targets, the presence of “areas unattainable for firing, including in the immediate vicinity of weapons (“ dead zones ”)” (hereinafter “unattainable targets”), which are protected by terrain in trenches, trenches, in a forest belt, in mountainous conditions, in urban conditions, and directly in buildings, including multi-storey buildings, significant dispersion and increased consumption of ammunition, low effectiveness of firing at protected by artificial and natural barriers, which creates certain difficulties with the task, as well as the incorrect performance of the personnel and weapons and equipment has a counter-battery effect.

The objective of the invention is the creation of a trunk that will allow you to work from a closed, protected position on targets, open and protected by folds of terrain, in trenches, trenches, in a forest belt, in mountainous conditions, in urban conditions and directly in buildings, multi-storey buildings, reduce the number of “unattainable targets”, reduce dispersion and reduce ammunition consumption, increase the effectiveness of firing at targets protected by artificial and natural barriers, which creates certain opportunities for the correct execution of the task, as well as to protect personnel, weapons and equipment from counter-battery impact.

As a result of its use, a technical result can be obtained that will allow to work more successfully, more efficiently from a closed, protected position on targets, open and protected by folds of terrain, in trenches, trenches, in a forest belt, in mountainous conditions, in urban conditions and directly in buildings, in including multi-storey buildings, reduce the number of “unattainable targets”, reduce dispersion and reduce ammunition consumption, increase the effectiveness of firing at targets protected by artificial and natural barriers, protect against counter-battery action, which creates certain opportunities for the successful completion of the task, as well as the opportunity to clarify, adjust previous and create new tabular data, conditions and rules of firing, which will allow us to design products for both old and new requirements, technical Sgiach tasks and settings.

The solution to this problem is achieved by the proposed "double ballistics barrel" (hereinafter referred to as the "barrel") under a round projectile, with a longitudinally extending groove, a cut length of 1.5 ~ 2.5 caliber (L1) from the muzzle, located on the inner surface of the barrel bore, with a gradual deepening to the muzzle, the opposite, opposite inner wall of the bore is reduced from the muzzle along the length by 0.2 ~ 1.5 caliber (L2) and, gradually, at a distance of 0.5 ~ 1.0 caliber (L3) from a shortened muzzle, the wall of the bore from the inside It becomes thinner and thinner, turning into a progressive slope at the muzzle, the barrel fastener is equipped with a mechanism for scrolling the barrel 360 degrees relative to the axis of the barrel channel with fixing and marking a given angle of rotation and direction of fire.

The characteristics of the barrel vary depending on the tasks to be solved, by changing all the structural elements tied into a single whole.

In the barrel we offer, shooting from a closed, protected position against targets that are open and protected by artificial and natural barriers is carried out thanks to a longitudinally located groove, a groove located on the inner surface of the barrel bore, 1.5 ~ 2.5 caliber (L1) long from the muzzle end, with a gradual deepening to the muzzle », the opposite, opposite inner wall of the bore is reduced from the muzzle along the length by 0.2 ~ 1.5 caliber (L2) and, gradually, at a distance of 0.5 ~ 1.0 caliber (L3) from a shortened muzzle with Yes, the wall of the barrel channel from the inside becomes thinner and thinner, turning into a progressive slope at the muzzle, the barrel fastener is equipped with a mechanism for scrolling the barrel 360 degrees relative to the axis of the barrel channel with fixing and marking a given rotation angle and direction of fire, which makes it possible to twist round the projectile in the transverse plane relative to the axis of the barrel channel, thereby allowing you to shoot from a closed, protected position on open and protected targets and to increase accuracy on closed, protected by artificial and natural barriers to the goals, as well as to be protected from counter-battery impact, and there is also the opportunity to clarify, adjust the old and create new tabular data, conditions and rules of shooting, which allows you to design products for both old and new requirements, technical specifications and parameters.

The essence of the proposed barrel is shown in the drawing.

The barrel consists of a barrel bore (1), a round projectile (2), a target (3), a muzzle (4a), a shortened muzzle (4b), a longitudinally located groove, a groove located on the inner surface of the bore (5) with a length 1.5 ~ 2.5 gauge (L1) (6), the opposite, opposite wall of the bore (7) is reduced in length by 0.5 ~ 1.5 caliber (L2) (8), the wall of the bore from the inside becomes finer and thinner, turning into progressive slope at the muzzle end (9) at a length of 0.2 ~ 1.0 caliber (L3) (10), gun barrel (11), small arms barrel (12), suit a natural or natural obstacle (13), a horizontal ballistic arc due to the influence of the Magnus effect “A” (14), a vertical ballistic arc due to the influence of the Magnus effect “B” (15), a ballistic arc “C” (16), a given angle of rotation of a longitudinally located the rifling set by the barrel scrolling mechanism (17), the minimum distance to the target (18), the maximum distance to the target (19), the axis of the barrel channel (20).

A round projectile (2) (Fig. 1a) (Fig. 1b), when moving in the bore (1), is swirled by powder gases through a longitudinally located groove (5), in the transverse plane relative to the axis of the bore (20), flies out of the channel the barrel (1) at maximum speed in the opposite direction, from a longitudinally located rifling (5), side along a ballistic vertical arc due to the influence of the Magnus effect "B" (15) (Fig. 4) in accordance with the "Magnus effect", at a given angle of rotation vertically down longitudinally mounted rifling (5), mounted fur ism barrel scroll (17), gradually decreasing circular velocity of the projectile (2), reduced effect "Magnus effect" on the round shell (13) and gradually enters the movement of the arc ballistic (16).

The proposed device operates as follows.

A round projectile (2) (Fig. 1a) (Fig. 1b) moves in the bore (1) of a gun (11), a small arms (12) under the influence of powder gases, aligning with a longitudinally located rifle (5) on a round projectile (2 ) powder gases begin to act from the groove (5), twisting it in the bore (1), along the length (L1) (6), to the muzzle end (4a), in the transverse plane relative to the axis of the bore (20), passing most powder gases along the wall of the bore with a longitudinally located rifle (5),

at the same time, under the influence of powder gases, from a longitudinally located rifling (5), a round projectile (2) begins to act on the opposite, opposite wall of the bore (7), while moving under the influence of powder gases and twisting, a round projectile (2) continues to act by pressing on the wall of the bore from the inside (9) along the length (L3) (10), passing a smaller part of the powder gases along the bore of the bore (9),

by reducing the length of the opposite, opposite wall of the bore (7) to (L2) (8), the round projectile (2), while continuing to move, is twisted under the influence of powder gases and, around the progressive steepness (9), a shortened muzzle (46) flies out of the bore (1),

a round projectile (2) flies out of the bore (1) to the opposite side, from a longitudinally located rifling (5), at a predetermined angle of rotation of a longitudinally located rifling (5), set by the barrel scrolling mechanism (17), with a maximum speed, ballistic a horizontal arc due to the influence of the Magnus effect "A" (14) (Fig. 2) or along a ballistic vertical arc due to the influence of the Magnus effect "B" (15) (Fig. 3), in accordance with the "Magnus effect".

When installing a longitudinally mounted rifling (5) in a horizontal position, with a horizontal elevation angle of the gun barrel (11), small arms (12), for firing horizontally to the right or left, set by the mechanism for scrolling the barrel (17) and the minimum distance to the target (18 ), a round projectile (2) will go to an “unattainable target” target (3) in a horizontal ballistic arc due to the influence of the Magnus “A” effect (14) (Fig. 2), horizontally bending around an artificial or natural barrier (13) (terrain folds , trench, trench, le opolosa, in mountainous terrain, urban and directly in buildings, including multistory et al.).

When installing a longitudinally mounted rifling (5), vertically upward, for firing down at close range, with an elevation angle of the gun barrel (11), small arms (12) substantially higher than the horizontal, set by the barrel scrolling mechanism (17) and the minimum distance to the target ( 18), a round projectile (2) will go to the “unattainable target” target (3) from above in a vertical ballistic arc due to the influence of the Magnus effect “B” (15) (Fig. 3), enveloping an artificial or natural barrier (13) from above number of “unreachable prices lei ”(in the folds of the terrain, trench, trench, forest belt, in mountainous conditions, in the city), in the shortest time, before the change in the operational situation.

When installing a longitudinally mounted rifling (5) vertically downward or slightly to the left or right, with a horizontal angle of elevation of the gun barrel (11), small arms (12), for firing upwards or several, to the right or left, set by the barrel scrolling mechanism (17) and the maximum distance to the target (19), a round projectile (2) will hit the target (3) first along the first vertical ballistic arc due to the influence of the Magnus effect "B" (15) (Fig. 4) persistently, then up, gradually, as speed reduction round projectile (13), the effect of the “Magnus effect” on the round projectile (2) is reduced and it gradually moves into motion along the second ballistic arc “C” (16) horizontally, and then down, to the target (3), enveloping artificial or natural from above hedge (13),

at the same time, the notch, removal and interpolation of the coordinates of the motion of a round projectile (2) by a ground artillery reconnaissance station, shot along the second ballistic arc “C” (16), shows imaginary, false coordinates of the gun, firing position, thereby protecting against counter-battery action, which creates certain opportunities for the successful completion of the task, the protection of personnel, weapons and equipment.
