RU2499977C2 - Ammunition consisting of two parts to be coupled immediately before loafing into gun barrel - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: ammunition consists of two parts to be coupled immediately before loading into gun barrel. One part is composed of artillery projectile without driving band with ledge at the body at its traditional location. Second part represents a driving band with recess of shape and size mating those of aforesaid ledge. Final mating occurs in gun barrel in initial moment of shot owing to axial and angular displacement of driving band relative to projectile body in barrel rifles.

EFFECT: higher unification of projectile.

Description

The invention relates to the field of military equipment and in particular to ammunition consisting of parts, the storage and transportation of which is carried out in protective containers.

Known ammunition (guided artillery shell), consisting of two parts - the control compartment and the "shell" compartment, laid in their respective protective containers (sealed cases). Parts of the ammunition are joined together just before loading into the barrel of the gun [RF patent No. 2144386, F42B 15/00, 39/00, publ. June 27, 1998].

The connection of the two parts is carried out using a bayonet lock by entering the seat of the "shell" compartment inside the control compartment with its subsequent rotation around the longitudinal axis of the projectile at a certain angle. This technical solution allows you to prepare a shell for the combat mission in the shortest possible time and in technical essence is the closest solution to the claimed one and is taken as a prototype.

However, when applying this ammunition to rifled artillery systems of the same caliber, but with different barrel lengths and different steepness of the rifling, they require lead belts of different sizes and shapes, which are optimal for each type of barrel. Therefore, to ensure the possibility of firing the indicated ammunition of the same caliber, a certain number of components will be required, differing in the presence of leading belts of different sizes, which prevents the unification of ammunition for a number of different artillery systems of the same caliber.

Thus, the objective of the invention is the creation of a single unified shell for existing and developed artillery systems of the same caliber.

The problem is solved in that the ammunition, consisting of two parts, mating with each other immediately before loading into the barrel of the guns of the artillery system, according to the invention, one part is made in the form of an equipped artillery shell without a leading belt with a protrusion on the body in the place of its traditional location, and the other part is a leading belt made with a recess corresponding in shape and size to the protrusion, and the final docking of the parts is carried out in the gun’s barrel at the initial moment of alignment but at the expense arising from the rifling of the barrel of the axial and angular displacement relative to the girdle leading projectile body.

The manufacture of the proposed standardized projectile is possible using the description of the method of fastening the leading belt of such a projectile [RF patent No. 2410632, F42B 14/02, publ. 01/27/2011], in which the protrusion under the leading girdle is made in the form of a flat conical radial protrusion in the form of an acute-angled triangle in cross section, the smaller angle of which is directed to the front of the projectile body. In contrast to the specified invention in the proposed ammunition, the protrusion on the housing may have a different configuration, for example, in the form of a convex or concave alive, an arc or wavy surface and other possible surfaces and their combinations. The greatest reliability of the fastening of the leading belt is achieved with a curved surface of its docking to the protrusion of the housing by the method of "friction welding" due to the longer length of the weld.

It is impossible to use a standardized artillery shell made without a leading belt; they cannot be fired from any artillery system. For this, a leading belt corresponding to a specific artillery system is required, which is put on before the shot on the corresponding protrusion on the body of the unified projectile.

The presence in the claimed invention features that distinguish it from the prototype, allows us to consider it consistent with the condition of "novelty."

New features (the performance of an ammunition in the form of an artillery shell without a leading belt with a protrusion on the hull in the place of its traditional location, and a leading belt with a recess corresponding in shape and size to the protrusion, and the final docking of the shell with the leading belt is carried out in the gun’s barrel at the initial moment of firing for due to the axial and angular displacements of the driving belt relative to the shell body arising in the grooves of the barrel) are not identified in technical solutions of a similar purpose. On this basis, we can conclude that the claimed group of inventions meets the condition of "inventive step".

The invention will be more clear from the following illustrated drawings, in which:

Figure 1 - view of the ammunition assembly with a leading belt;

Figure 2 - view of the leading girdle with a curly notch;

Figure 3 is a view of the shell of the shell with a figured protrusion.

Ammunition consists of two parts that fit together just before loading the gun into the barrel. One part is made in the form of an artillery shell 1 without a leading belt with a figured protrusion 2 on the body in the place of its traditional location, and the other part is a leading belt 3 made with a figured recess 4 corresponding in shape and size to the protrusion (Figs. 1, 2, 3). The width of the leading belt 3 is determined by calculation, depending on the size of the gun barrel. The final docking is carried out in the gun barrel at the initial moment of the shot due to the axial and angular movements of the driving belt 3 relative to the shell of the projectile 1.

The tests (on a lathe) simulating the movement of the driving belt 3 relative to the protrusion 2 of the fragment of the shell 1, showed that in firing conditions, the fastening of the driving belt 3 to the shell of the shell 1 is ensured, which is necessary for its required performance in the barrel and on the flight path.

Putting the lead belt 3 in place of its traditional location on the shell of the projectile 1, the ammunition is placed in the barrel of the gun. At the initial moment of the shot due to the axial and angular movements of the leading belt 3 relative to the shell of the projectile 1 arising in the rifle of the gun’s barrel, the ammunition is finally assembled and necessary used for its intended purpose.

Thus, the presented information when using the claimed invention allows to provide the following combination of conditions:

- creation of a single unified shell for existing and developed artillery systems of the same caliber;

- ensuring quick and convenient preparation of ammunition for combat use by forces of military units, and consequently, a mobile response to changing circumstances;

- reducing the cost of production of shells of artillery shells and equipping arsenals with cheaper artillery ammunition by increasing the intraspecific unification of these ammunition.

For the claimed invention in the form in which it is described in the claims, the possibility of its implementation using the devices described in the application and known prior to the priority date is confirmed.

Therefore, the claimed invention meets the condition of "industrial applicability".
