Description

The invention relates to ammunition, and in particular to cartridges of small arms, both rifled and smooth-bore.
The purpose of the invention is to increase the effectiveness of the cartridge when firing a rifled weapon.
Figure 1 shows a bullet cartridge small arms, side view; figure 2 cross section aa in figure 1; in Fig. 3 a pallet, side view: in Fig. 4 is a pallet, a view along arrow B in Fig. 3; figure 5 - cartridge small arms. comprising a bullet with a pallet placed in a sleeve; on fi.6 revolving bullet in the pan, side view; Fig.7 is a cross section bb in Fig.6; in Fig.8 is a cross section GG in Fig.6.
The small arms cartridge contains a sleeve 1, in which a powder charge 2 and a bullet 3 are placed in a detachable pan 4. The bullet 3 is made, for example, of steel or lead, with a diameter essentially equal to the caliber of the barrel, although slightly less so that it is not interaction with the rifling of the barrel when firing. On the outer surface of the bullet 3 there are V-shaped longitudinal grooves. 5, for example, four, the angle of which at the base in this case is 90 °. Between the grooves 5 four elongated ribs 6 are formed, forming a cross section in cross section (Fig. 2). The grooves 5 are made over the entire length of the bullet 3, including its head tapering part 7. Performing the head part 7 of the bullet 3 tapering to the top increases the penetration ability of the bullet 3 when firing at armored plates. The grooves 5 can be not only longitudinal, but also helical, and their profile can also be U-shaped. The pallet 4 is made of elastic plastic, for example nylon, and has a split part, in which fingers 8 are formed with an outer cylindrical surface according to the number of grooves 5 of the bullet 3, and a continuous part, on which the leading girdle 9 and the shoulder part 10 are made. Each finger 8 fits snugly into the corresponding groove 5 of the bullet 3, while the thickness of the finger 8 can be equal to the depth of the groove 5. The length of the fingers 8 can be made to the top of the bullet 3. In this case, the front of the fingers 8 absorb the impact of the bullet 3 when it enters the rifling trunk protecting the sa We rifle barrel or revolver from damage. At the free end of the fingers 8 there is a groove 11 for patronage, in which the sleeve 12 of the sleeve 1 is squeezed during cartridge assembly. Plastic pallet 4 provides reliable sealing of the cartridge, which is necessary in conditions of long-term storage. To reduce the weight of the pallet 4, fingers 8 can be hollow. 6-8 show a tray 4 for a revolving bullet. The fingers 8 of the pallet 4 in this case protrude beyond the tapering part of the bullet 3, thereby forming a continuation of the cylinder. This is especially important for a revolver bullet, which, like the lead bullet of a smoothbore gun, has a small relative length and, therefore, over most of its length it should be tapering to ensure streamlined shape. The elongated fingers 8 ensure the stability of the bullet 3 when it passes through the channel of the gun barrel.
When fired, the leading belt 9 of the pallet 4 interacts with the grooves of the barrel channel, while the rotation is transmitted to the bullet through the fingers 8, which are engaged with the corresponding ditches 5 of the bullet 3. Since the pallet 4 is made of plastic, it creates less friction in the barrel channel, in As a result, most of the initial energy of the bullet is converted into kinetic, and a smaller part of this energy is converted into heat and spent on heating the barrel, as well. The tight installation of the fingers 8 of the pallet 4 in the grooves 5 of the bullet 3 prevents the breakthrough of the powder gases through the grooves 5. An axial channel can be made in the pallet, as a result of which, under the influence of the pressure of the powder gases, the pallet 4 is pressed against the walls of the barrel channel and, therefore, the obturation of the powder gases is improved . In another embodiment, the same effect is provided by the wedge-shaped shape of the portion of the bullet 3 interacting with the pallet 4. When the rotating bullets 3 in the pallet 4 emerge from the channel of the gun barrel, the fingers 8 of the pallet 4 diverge in the radial direction, freeing the grooves 5 of the bullet 3, and under the pressure of the incoming flow the air of the pallet 4 is completely separated from the bullet 3. The stabilization of the bullet 3 on the flight path is ensured by its rotation (both due to grooves of the barrel channel and spiral grooves, especially when shooting from smooth-bore weapons), and aerodynamically the plumage formed by the ribs 6. The interaction of the bullet 3 with the obstacle ensures a high penetrating effect of the bullet due to both its high kinetic energy, due to the combination of the advantages of caliber and sub-caliber ammunition in its design, and its rotation during the interaction.
For example, a standard Remington system rifle with a caliber of 0.223 inches (5.56 mm) has a bore diameter of 0.219 inches (5.56 mm) along the rifling fields, 0.224 inches (5.69 mm) rifle diameter, width grooves of 0.07 inches (1.78 mm). For a bullet corresponding to this barrel, the maximum diameter is 0.21875 inches (5.56 mm), the width of the ribs 6 is 0.060 inches (1.52 mm). The length of bullet 3 is 1.127 inches (28.62 mm). The nominal diameter of the shoulder portion 10 of the pallet 4 is 0.216 inches (5.49 mm), the diameter of the leading belt 9 is 0.224 inches (6.69 mm), the width of the leading belt 9 is 0.062 inches, and the length of the shoulder portion 10 of the tray 4 is 0.125 inches (3.17 mm).
