Definitions

  • the cartridge for small arms The invention relates to the field of ammunition, in particular for the design of small arms cartridges, and can be used in the manufacture of cartridges of various calibers and purposes.
  • the disadvantages of the known cartridge case include the combination of low strength and ductility of the walls of the cartridge case with technological flaws associated with an increase in the thickness of the cartridge case and subsequent more severe jamming of the cartridge case walls when firing at high pressures of powder gases (more than 3000 kgf / cm 2 ), which leads to chaotic rupture of the walls of the liner during its extraction from weapons.
  • Known cartridge for small arms containing a sleeve with a housing, a bottom and a dulce, a powder charge, a capsule and a bullet.
  • a recess or flat is made, the width of which is 0.2- 0.5 [RU Xe2309369 C2, F42B5 / 00, 2007].
  • the disadvantages of the known cartridge include periodic rupture of the sleeve body along its length, occurring from a groove or flange to a slope sleeves. The appearance of such discontinuities is explained by the fact that the recess or flange performed on the liner is a hub of the tensile stress of the liner material. In addition, making grooves and flats on the surface of the sleeve body is a rather laborious process.
  • a small arms cartridge including a capsular sleeve, propellant charge and a bullet.
  • the case body contains a bottom part, a groove, as well as a cone-shaped body, ramp and dulce.
  • a strain relief is made on the outer surface of the sleeve body, in the area of its possible rupture or jamming in the chamber.
  • the generatrix of the strain relief is made in the form of a combination of straight parallel or inclined at an angle of 0.0-3.0 ° to the longitudinal axis of the cartridge and radial concave or convex lines.
  • Generator creates a gap between the conditional ruler and the edges of the compensator.
  • the length compensator is made equal to 0.2-0.9 of the sleeve body length. [RU JVS 2470254 C I, F42B5 / 00, 2012].
  • the disadvantages of the known cartridge include increased wear of the chamber and jamming of the spent sleeve as a result of systematic impacts of the walls of the shell against the walls of the chamber with each shot.
  • this design is acceptable only for bottle-shaped liners, which limits the functionality of the cartridge.
  • the basis of the invention is the task of improving the design of the cartridge of small arms by improving the design of the sleeve to ensure its reliable operation, expand the functionality and simplify the technology of its manufacture.
  • a damper is made in the form of an internal or external recess in the bottom of the sleeve in the vicinity of the capsule socket.
  • the inner or outer recess is made in the form of a continuous ring of a cylindrical, triangular, trapezoidal or spherical shape or individual cavities of a cylindrical, triangular, trapezoidal or spherical shape.
  • the recess in the form of a solid ring is made with a width of from 0.001 to 1, 2 and a depth of from 0.001 to 1, 3 caliber cartridge.
  • the number of individual recesses in the bottom of the liner is at least three with a recess width of 0.001 to 1.5 and a depth of 0.001 to 1.6 caliber cartridge.
  • the implementation of the external or internal damper or damper depressions in the bottom of the sleeve body in the vicinity of the capsule socket creates an air cavity between the gate mirror and the bottom of the sleeve, and also increases the useful volume of the sleeve, minimizing negative deformation changes in the external geometry of the sleeve during the shot at high pressures (over 3800 kgf / cm), preventing tearing and jamming of cartridges and ensuring reliable operation of the cartridge of small arms.
  • damper recess or recesses are performed in one maximum in two operations, which allows the production of sleeves without the use of expensive equipment and complex equipment.
  • the design of the inventive cartridge is acceptable for both bottle and non-bottle liners, which expands its functionality.
  • Figure 1 schematically shows a cartridge of small arms with a bottle-shaped sleeve, on the outer or inner surface of which a damper recess is made in the form of a continuous ring;
  • figure 2 - cartridge small arms with a sleeve of a bottle shape, on the outer or inner surface of which a damper is made in the form of separate recesses;
  • Fig.Z - cartridge small arms with a sleeve is not a bottle shape, on the outer or inner surface of which a damper recess is made in the form of a continuous ring;
  • figure 4 - cartridge small arms with a sleeve is not a bottle shape, on the outer or inner surface of which a damper is made in the form of separate recesses.
  • the small arms cartridge contains a sleeve 1, a powder charge 2 and a bullet 3.
  • the sleeve 1 contains a housing 4 and a bottom part 5, in which a damper is made in the form of a capsule socket 6 in the form of a continuous inner annular recess 7, or a continuous annular external recess 8, or not less than three separate internal recesses 9, or at least three separate external recesses 10.
  • the shape of the recesses may be cylindrical, triangular, trapezoidal or spherical shape and depends on the wear resistance of the tool during the manufacturing process of the sleeve.
  • the inventive cartridge of small arms is as follows.
  • powder gases act on the bullet 3, forcing it to move along the barrel, and on the inner part of the sleeve 1, pressing the side walls of the sleeve 1 to the walls of the chamber, and the bottom part 5 of the sleeve 1 to the mirror of the shutter.
  • plastic and elastic deformation of the housing 4 of the sleeve 1 occurs.
  • the bottom part 5 of the sleeve 1 moves, abuts against the shutter mirror and compresses the damper recesses 7, 8, 9, 10, reducing the air cavity between the bottom part 5 of the sleeve 1 and the shutter mirror .
  • the sleeve 1 is stretched, its internal volume, the hardening of the walls of the housing 4 s 1 and the time of the pressure of the powder gases through the bottom 5 on the shutter mirror increase.
  • the increase in the internal volume of the sleeve 1 favorably affects the combustion characteristics of the powder charge 2, reduces the peak pressure spikes, smoothing the overall combustion diagram of the powder charge 2, which prevents longitudinal or transverse ruptures of the sleeve 1 and reduces the oscillation of the weapon during the shot.
  • the increased hardening of the walls of the housing 4 of the sleeve 1 improves the elastic properties of the material of the sleeve 1, as a result of which, after the shot, when the pressure in the barrel drops, the sleeve 1 is compressed more intensively, returning to the original or close to the original geometric dimensions, creating a uniform circular air gap between the side walls of the housing 4 liners 1 and the walls of the chamber, as well as between the bottom 5 of the liner 1 and the shutter mirror, thereby preventing jamming of the liner 1 during extraction.
  • the increase in the exposure time of the pressure of the powder gases through the bottom part 5 of the sleeve on the shutter mirror favorably affects the ergonomic indicators of the shot.
  • the shooter feels more comfortable when the pressure of the powder gases during the shot is maximally stretched in time, which creates the illusion of a decrease in recoil.

Abstract

L'invention se rapporte u domaine des munitions de guerre, concerne notamment une structure de cartouche pour arme à feu, et peut être utilisée pour fabriquer des cartouches de calibre divers et à vocations diverses. La cartouche comprend un étui avec un corps, une partie fond et un logement d'amorce, une charge de poudre et une balle. Dans la partie fond de l'étui dans la région du logement de l'amorce se trouve un amortisseur en forme de renfoncement interne ou externe. On assure ainsi un bon fonctionnement de la cartouche, on augmente les capacités fonctionnelles et on simplifie les techniques de fabrication.
