Description

The invention relates to ammunition, in particular to designs of small arms cartridges for various purposes. The invention relates to ammunition of small arms, in particular to the construction of bullets.

Known technical solution "ARMORING-TRACING BULLET" (Pat. RF №2441194, publ. 01.27.2012, analogue). Armor-piercing tracer bullet contains a bimetallic shell, a core, a cup with a tracer composition and a cavity in front of the core in the head of the shell. The core has an animated head and a cylindrical tail. The tail of the core is made in length (0.65-0.80) d, the total length of the bullet is (4.7-5.1) d, and the distance from its top to the top of the core is (0.12-0.17) L where d is the caliber of the bullet, and L is its length. It is possible to create armor-piercing tracer and armor-piercing incendiary-tracer bullet.

The design of this bullet and similar bullets eliminates the possibility of shock when it enters a biological object. These bullets do not meet modern requirements for target weapons.

Known technical solution "BULLET FOR CARTRIDGES OF THE SHOOT WEAPON" (Pat of the Russian Federation No. 2516879. Publish. 05.20.2014, prototype). The bullet contains a metal shell with an elongated tail, with a core-filler located in the shell. The elongated tail portion of the bullet shell is tightly compressed to prevent the core filler from spilling out of the shell. The tail of the shell is made in the form of a truncated cone with a vertex directed in the opposite direction from the head. As a bullet core filler, a shot from a material with a specific gravity of 4.0-8.0 g / cm ³ is used — shot from cast iron, steel, bronze, copper. An improvement in ballistic performance is achieved.

The design of this bullet eliminates the possibility of shock when it enters a biological object. These bullets do not meet modern requirements for target weapons.

The objective of the invention is to eliminate the noted drawbacks, namely increasing the effectiveness of small arms due to shock effects on a biological object.

The problem is solved due to the fact that in the known pool containing a bimetallic shell, the core is made of hard alloy, an electric pulse generator is additionally installed in the cavity of the rear part, including: a piezoelectric element, a capacitor, diodes and a mechanical key, the piezoelectric element is connected through the diode to the tail parts of the bimetallic shell, and the second terminal to the capacitor, the second terminal of which is connected through a diode and a mechanical key to the main part of the bimetallic shell, which is separated by a dielectric Rick from the tail part of the bimetallic sheath.

In the existing designs of bullets, this set of essential features has not been identified, which allows us to consider this technical solution to meet the criterion of "novelty."

Installation in the rear part of the bullet of an electric pulse generator, comprising: a piezoelectric element, a capacitor, diodes and a mechanical key, a piezoelectric element connected via a diode to the tail part of the bimetallic shell, and a second output to a capacitor, the second output of which is connected through the diode and the mechanical key to the main part bimetallic shell, which is separated by a dielectric from the tail of the bimetallic shell, enhances the damaging effect of a bullet when it enters any part of the body.

The claimed combination of distinctive features in the sources of patent and scientific and technical information is not found, which allows us to consider this technical solution satisfying the criterion of "inventive step".

In FIG. 1 shows a General view of the bullet, figure 2 - shows the electrical circuit of the current generator located in the rear of the bullet.

In FIG. 1, the following designations are adopted: the main bimetallic shell of the bullet - 1, the dielectric - 2, which separates the main part of the bimetallic shell (1) electrically from the tail, the core - 3, the points: “a” and “b” of fastening the inputs of the current generator to the main and tail parts of the bimetallic shell (1).

In FIG. 2. the following notation is accepted: mechanical key - “k”, diodes - D ₁ , D ₂ , capacitor - C, piezoelectric element - Q. The conclusions of the piezoelectric element (Q) are connected through the diodes (D ₁ and D ₂ ) to the terminals of the capacitor (C) . One terminal of the capacitor (C) is connected to the tail of the bimetallic shell, point b, the second terminal of the capacitor (C) is connected through the mechanical key “k” to the main part of the bimetallic shell (1) of the bullet, point “a”.

где приняты следующие обозначения: Е - электрическое поле внутри пластины [В], h - толщина пластины [м], Р_х - поляризация пластины Р_х=d₁₁·σ_х, d₁₁ - постоянная, называемая электрическим модулем, ε - диэлектрическая проницаемость кварца,

- механическое напряжение, действующее параллельно оси х, [Па], m - масса, действующая на пластину кварца, [кг], g - ускорение силы тяжести, [m/с²]. Конденсатор заряжается до напряжения φ. По окончании ускорения пули механический ключ (k) соединяет вывод конденсатора (С) с основной частью биметаллической оболочки (1). За время полета пули до цели конденсатор (С) получает дополнительный заряд с поверхности биметаллической оболочки, возникающий за счет ее трения о воздух.The device operates as follows. When firing a bullet under the influence of powder gases, it acquires acceleration - (g), while the core (3) produces a mechanical action by pressure on the mechanical key (k), disconnecting the capacitor lead (C) from the main part of the bimetallic shell of the bullet (1), and the mechanical effect on the piezoelectric element (Q). The piezoelectric element undergoes deformation and generates a stress determined from the equality

where the following notation is used: E is the electric field inside the plate [B], h is the thickness of the plate [m], P _x is the polarization of the plate P _x = d ₁₁ · σ _x , d ₁₁ is a constant called the electric module, ε is the dielectric constant quartz

- mechanical stress acting parallel to the x axis, [Pa], m is the mass acting on the quartz plate, [kg], g is the acceleration of gravity, [m / s ² ]. The capacitor charges to voltage φ. At the end of the bullet acceleration, a mechanical key (k) connects the capacitor terminal (C) to the main part of the bimetallic shell (1). During the flight of the bullet to the target, the capacitor (C) receives an additional charge from the surface of the bimetallic shell arising from its friction against the air.

When a bullet meets an obstacle, the piezoelectric element (Q) undergoes deformation and generates a voltage that charges the capacitor (C). Between the connection points of the capacitor (C) located in the main and tail parts of the bimetallic shell of the bullet, a potential difference is created, which causes the discharge of the capacitor (C) when the bullet enters the body of the animal and the shock effect that paralyzes the motor functions.

The proposed technical solution can be implemented industrially. Bullets can be used in commercial hunting, increasing hunting efficiency and reducing the number of wounded animals.
