Description

The invention relates to the field of engineering and is intended for throwing solids, shells and can be used in various industries, as well as for the design and manufacture of rifled, smooth trunks of various types and ammunition for them.

Known products the barrel of a firearm (Patent RU No. 2150063 of 03.25.1999 MPK8 F41A), the pallet for a sub-caliber projectile of weapons (Patent RU No. 2258892 of 02.04.2004 IPC F41B) have a fundamentally similar design of ammunition for both rifled and smooth-bore weapons with a muzzle brake, from small to large calibers, with tabular tactical and technical characteristics and allows you to perform tasks at specific ranges with a certain accuracy.

The disadvantage of existing barrel systems and their ammunition is significant vibration during firing of the barrel and missile body, shell, disruption from rifling up to the destruction of the driving belt, shell of bodies, shells, which creates significant dispersion, reduced accuracy, increased consumption of ammunition, as well as a significant limitation in the capabilities of recoil devices and a muzzle brake compensator, which does not significantly increase the charge power, and therefore increase the firing range.

The objective of the invention is the creation of ammunition, which will significantly reduce the vibration of the barrel and missile body, the projectile during firing, eliminate breakdowns from rifling, prevent destruction of the leading belt, shell of bodies, shells, reduce the dispersion of shells, improve the accuracy of missile bodies, shells, reduce the pitch of the rifling , and also significantly improve the capabilities of the muzzle brake compensator, which means to increase the charge power, thereby increasing the table firing range.

As a result of its use, a technical result can be obtained in which there is a decrease in the vibration of the barrel and missile body, the projectile during firing, the possibility of disruption from rifling and destruction of the leading belt, shell of bodies, shells is excluded, the target axis being saved to the missile body, projectile, thereby, the dispersion of propelled bodies, shells is reduced, the accuracy of propelled bodies, shells is improved, and the conditions for a significant improvement in the capabilities of the muzzle brake-compensator appear, thereby, as flax reduce rifling step, and significantly increase the tabular firing range that allows the construction of compact products, both for the old and for the new requirements, technical specifications and parameters.

The solution to this problem is achieved by the proposed "obturator pallet" (hereinafter - the OP pallet) according to the caliber of the barrel, by placing between the charge and the missile body, a shell, with a shell, a leading belt, on the outer surface of the OP pallet, the part of the pallet facing the shell is made in the form of a truncated cone, the part of the pallet facing the charge is made in the form of two truncated conical surfaces, in the parts of the pallet facing the projectile, to the charge and in the central part of the pallet, there is a longitudinal through channel of ignition Nia tracer element.

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

In the OP pallet we offer, vibration reduction during shooting and the muzzle brake capabilities are improved due to the OP pallet located between the charge and the missile body, the shell, made according to the caliber of the barrel with a shell, a leading girdle, on the outer surface of the OP pallet, part of the pallet facing the projectile is made in the form of a truncated cone, the part of the pallet facing the charge is made in the form of two truncated conical surfaces, in the parts of the pallet facing the projectile, to the charge and in the central part of the pallet, a longitudinal through channel of ignition of the tracer element is provided, which eliminated the possibility of disruption from rifling and destruction of the leading girdle, shell of bodies, shells, and, therefore, to keep the target, missile, shell, aiming axis, thereby reducing the dispersion of bodies, shells, improve accuracy throwing bodies, shells, and also there is a significant opportunity to both significantly reduce the pitch of the rifling, and significantly increase the table firing range, which allows you to design products compactly, as for previous and new requirements, technical specifications and parameters.

The essence of the proposed pallet OP shown in the drawing.

The OP tray consists of the housing of the OP tray (Fig. 1), a driving shell, driving belts (1), a truncated cone (2), a top of a truncated cone (3), an ignition channel of the tracer element (4), a truncated conical surface (5), truncated conical surface (6), part of the barrel of the muzzle brake compensator (Fig. 2), the combat surface of the muzzle brake compensator (7), the parasitic surface of the muzzle brake compensator (8).

The OP pallet presses the shell, the leading belt (1) onto the barrel, and simultaneously pushes the missile body, the projectile out of the bore, with the tip of the truncated cone (3), shields it from the effects of powder gases from the bore and directs them to the combat surface of the muzzle brake compensator (7 )

The proposed device operates as follows.

The body of the OP pallet (Fig. 1), moving in the barrel channel, presses with a shell leading the belt (1) onto the barrel, simultaneously through the ignition channel (4) in the center of the pallet, the OP ignites the tracer in the bottom of the missile body, projectile and pushes with the tip of the truncated cone (2) (3) a missile body, a projectile from the bore without disruption from rifling and destruction of the leading belt, shell. After the missile body, the projectile leaves the bore, the OP pallet (1), while continuing to move in the bore, obscures the missile body, the projectile, especially the feathered one, which is not aerodynamically shaped from the bottom, from the parasitic effect of powder gases escaping from the barrel muzzle Thus, the missile body, the projectile moves from the muzzle of the barrel along a given axis of aim.

Powder gases, as they are pushed out under the bottom of the OP (1) (Fig. 1), exit the barrel along a truncated conical surface (5) towards the combat surface of the muzzle brake compensator (7) (Fig. 2), restraining the recoil . Gradually, the powder gases, as the OP pallets are further pushed out (1), continue to exit the bore along the truncated conical surface (6), towards the combat surface of the muzzle brake (7), bypassing the parasitic muzzle surface along the truncated conical surface (6) brakes (8) while continuing to restrain the rollback movement.

Powder gases, pushing the OP tray (1) (Fig. 1) out of the bore, bypass the OP tray (1) along the truncated conical surfaces (5) (6), thereby the OP tray (1), moving after the body being thrown, the projectile, for a certain distance, time obscures the missile body, the projectile from the parasitic effects of powder gases, not allowing the missile body, the projectile knock down from a given aiming axis.
