Technical field

AND

The technical solution relates to the field of small-caliber ammunition and especially the construction of non-toxic missiles with increased stopping effect. The missile is intended primarily for combat deployment, but can also be used in training shooting or for other practical purposes.

BACKGROUND OF THE INVENTION!

A wide variety of missile types for pistol and turret ammunition of various designs is known, generally suitable for any small-caliber ammunition.

Most often, the bullet consists of a shell and a core, the shell being made of steel or brass or other copper alloys and the surface of the shell is provided with an anti-corrosion treatment. The core of the missile is then usually made of lead or its alloys.

So-called homogeneous missiles are also known which are made of a single material, usually brass. The advantage of these bullets is primarily the simple and therefore inexpensive manufacture itself, but they are relatively expensive in terms of material when it is brass, and they have other disadvantages associated with their relatively low weight relative to lead. They are also usually toxic, albeit less than lead shots.

Another known type is frangible bullets, which are bullets made of powdered metals or metal oxides and binders, which are sintered to a solid consistency in the manufacturing process, but which disintegrates by impact on a target or solid obstacle. This known type of missile is suitable for use in areas where secondary damage is to be minimized.

The aforementioned known missile solutions generally have the following disadvantages and drawbacks:

Lead used on the missile core is highly toxic, copper and its alloys are unsuitable for their environmental impact and, in addition, the vast majority of brass alloys used on the shell have high hardness, which adversely affects the gun barrel as it causes high wear on its borehole. In addition, other high mechanical properties of the brass, namely its strength and toughness, result in little or no deformation of the projectile in the soft target, thereby significantly reducing the projectile's effectiveness on the target, in particular its destructive and stopping effect.

These missiles, when impacted on a soft target, little deformed mainly in the front and thus penetrate the target material to transmit energy on a relatively longer orbit than the bullet, which when hit on the target quickly and greatly increases its diameter.

Similarly, steel shell shells exhibit even greater disadvantages.

By design and effects, fangible missiles are designed primarily for specific conditions, especially in places where there could be a danger to uninvolved persons or damage to important objects such as aircraft, etc. On the other hand, higher destructive effect35 is undesirable for these missiles.

The aim of the technical solution is to eliminate the above-mentioned drawbacks and to solve the bullet construction, which has an increased deformation capability and thus an increased destructive effect and consequently an increased stopping ability due to a significant increase in the projectile diameter after penetration into soft matter. Another object is to provide a projectile design that, while maintaining the above-mentioned effects, allows an efficient technology of production missiles with appropriate ballistics, made of non-toxic materials and not interfering with the automatic function of used weapons.

The essence of the technical solution

The essence of the missile with increased stopping effect according to the present invention, particularly suitable for combat deployment and consisting of a shell and a core having a different specific weight, is that the shell is made of non-toxic metal and the core is formed by at least one powder metal and / or metal oxide and flexible binder in an amount of 5 to 40% by weight.

It is also essential that the bullet shell is made of aluminum or titanium. It is also essential that the core may be composed of two parts housed one behind the other, the composition and specific gravity of the two core parts being different.

It is also essential that the resilient binder is an acrylamide gel or Agarosa gel.

Increased missile deformation after impact on the target is achieved mainly by using a flexible binder. Suitable resilient binders are those which exhibit a relatively high sustained elasticity even after the core has been pressed into the shell of the projectile and retain this flexibility throughout the useful life of the projectile.

The choice of materials and the weight of the projectile components are governed by the ballistic requirements for the projectile, the processability of the input materials into the projectile components, the materials used must not be toxic, and the desired final shape and weight of the projectile. By means of a suitable combination of powder metals and metal oxides and a suitable binder, all parameters of the projectile can be controlled.

Clarification of drawings

Fig. 1 shows a first exemplary embodiment of a projectile according to the invention and Fig. 2 shows a second exemplary embodiment of a projectile according to the invention.

Examples of technical solutions

Example 1

The 9 mm caliber missile shown in Fig. 1 has a shell 1 which is made of a non-toxic aluminum or titanium material. A core 2 consisting of a mixture of two powder metals, namely 30% by weight of Fe and 40% by weight of W, which are joined by a flexible binder, in this case silicone rubber, which is contained in an amount of 30% % by weight.

The bullet according to the invention is easily and efficiently manufactured by pressing the core 2 of the bullet produced by dry blending of a mixture of metals with silicone rubber into the shell 1 of the bullet produced by the progressive molding, this mixture is subsequently homogenized in malaxer and then mixed volumetrically or by mass into the shell and projectile, which is subsequently covered by the cover disc 4 and the assembled projectile is closed by forming a skirt 3 by bending the end of the shell 1 inwards. It is preferred to use rubber which polymerizes by the action of the added activator.

Example 2

The 9 mm bullet shown in FIG. 2 has a shell 1 which is made of a non-toxic aluminum material. The front core 5, which consists of three powder metals, joined by a flexible binder, for example a gel, is pressed into the shell 1 in the projectile production process. All used metals W, Fe and Sn are non-toxic.

The mixture for the front core 5 comprises 30% by weight of Sn, 40% by weight of W, 15% by weight of Fe and 15% by weight of a polyacrylamide gel.

A rear core 6 formed of three of the same cracking metals as the front core 5 is pressed into the rear of the bullet shell 1 on the front core 5, but in a different weight ratio. The back core 5 contains 35 wt% Sn, 40 wt% W and 20 wt% Fe. Again, the flexible binder is a 5% by weight polyacrylamide gel.

The production of the projectile is analogous to that of Example 1 except that the two-piece core 5, 6 is inserted into the shell I in two steps.

Example 3

According to a third embodiment of the invention, a 9 mm caliber bullet is formed, which looks similar to the bullet of the first embodiment shown in Fig. 1. Again, the bullet comprises a shell 1 which is made of a non-toxic aluminum material. A core 2, which in this case consists of a mixture of three non-toxic powder metals joined together by a flexible binder, for example a gel, is pressed into the shell in the projectile production process. The core is then composed of a mixture comprising 30% by weight Sn, 40% by weight W, 20% by weight Fe and 10% by weight Agarosa gel.

The production process of the projectile is similar to that of Example 1.

io Example 4

The design of the 9 mra caliber missile according to the fourth exemplary embodiment is similar to that of Fig. 1.1 here, the shell is also made of non-toxic material - aluminum. A core 2, which consists of two powdered metals, joined by a flexible binder, for example a gel, is pressed into the shell in the projectile production process. The two non-toxic powder metals are present in the mixture in a ratio of 25% by weight 15 µm Sn and 40% by weight W. The flexible binder in this case is Agarosa gel, which is contained in 35% by weight.

The production process of the projectile is analogous to the previous examples.
