Description

 The invention relates to the field of shooting technology and can be used in devices for joint or separate throwing of two bodies.

 There are known systems of historical small arms with barrels being charged through the barrel muzzle described, for example, in the book “The Material Part of Small Arms” edited by A. A. Blagonravov, part one, pages 6-13, edition of Oborongiz NKAP, Moscow, 1945. The main disadvantage of these systems is the inconvenience of operation.

 Known line-throw device based on a Beretta signal pistol described in [1] This device includes a Beretta signal pistol, a tench and a piston load mounted on the outer surface of the barrel muzzle. Throwing a piston load with a line is carried out by a signal cartridge at a distance of 50 meters. When a muzzle pressure of powder gases is fired, the initial piston speed is informed to the load piston. The disadvantage of this device is that its use is limited by the low power of the signal cartridge and the inability to use powerful live ammunition.

 The prototype of the invention selected installation for throwing a line with "Cat" type NR 8120 PKВ described in [2] This installation includes a mortar type machine and a container-launch tube with a line and "Cat". Container - the launch tube is replaced after each shot. The launch tube is the barrel charged through the barrel, in which the powder propellant charge, piston and tench with the "Cat" are placed. When fired by the pressure of powder gases, the piston moves to the muzzle of the pipe and throws a line with the "Cat". The disadvantages of this device are the use of a disposable container-launch tube, the use of an intermediate piston part and the inability to use standard propelling charges.

 The aim of the invention is to eliminate the above disadvantages, simplifying operation and design, providing the possibility of using regular live ammunition for throwing loads and shells of used cartridges with the possibility of varying their relative relative speeds.

 This goal is achieved by the fact that in a propelling system containing a barrel charged through the barrel, mechanisms for firing a shot located in the bore of the barrel a powder charge and a missile load, characterized in that the powder charge is a propellant charge of a standard unitary cartridge placed in its sleeve, a missile load made in the form of a standard unitary cartridge shell, and the cartridge is placed in the cavity of the hollow cylinder to a fixed depth.

 At the same time, a smooth transition from the diameter of the bore to the diameter of its bottom was made in the barrel bore along the length of the bottom section of the liner.

 In addition, the hollow cylinder is made blind, closed from the side of the barrel muzzle, and the cartridge is placed in it to a depth that ensures clipping of the bottom portion of the liner during firing.

 The cavity of the hollow cylinder is made with a through diameter equal to the diameter of the cartridge case, and the cartridge is placed in the cylinder to a depth that ensures that the bottom section of the cartridge is cut off during firing.

 The cavity of the hollow cylinder is made with a through diameter equal to the diameter of the cartridge case, the tail (hollow cylinder) is made according to the geometry of the transition of the bottom of the bore to its side walls, and the cartridge is placed in the hollow cylinder to the full length.

 The cavity of the hollow cylinder is made through, the diameter of the head of which is selected from the condition of the projectile departure, while the cartridge is placed in the cavity of the hollow cylinder to a depth that cuts off the bottom portion of the liner during firing.

 In our opinion, the proposed propelling system satisfies the criterion of "inventive step", since it does not follow explicitly from the available prior art from available sources of information in this field.

The invention is illustrated using the drawings, where:
in FIG. 1 shows a propelling system with a hollow cylinder made blind, closed from the barrel muzzle;
figure 2, 3, 4 depict embodiments of the propelling system with hollow cylinders having through cavities.

 The throwing system comprises a barrel 1 charged through the barrel with a smooth transition 2 from the diameter of the barrel bore to the diameter of its bottom, in which a hole 3 is made for passage of the striker of the trigger mechanism (not shown in the drawing). In the hollow cavity 4 (FIG. 1) or in the through cavity 5 (FIGS. 2 and 3) of the hollow cylinder 6, a standard unitary cartridge 7 with its shell 8 of any 8 of any standard small arms is placed. In the hollow cylinder 6 (in FIG. 4), a hole 9 (the tail of the hollow cylinder) is made with a diameter equal to the diameter of the cartridge sleeve, and the hole 10 (head of the hollow cylinder) is smaller than the diameter of the cartridge sleeve to obtain variable speeds of the hollow cylinder and the projectile. Smooth transition 2 increases the reliability of extraction of the bottom section of the liner. For example, a line 11 can be attached to the hollow cylinder 6. The cartridge 7 is held in the hollow cylinder 6 by means of a plate (spring) 12 (view A of FIG. 5). The hollow cylinder 6 is sent into the bore of the barrel 1 to the stop 13 spring-loaded axially by a flexible element 14 attached to the barrel, for example by spot welding. From axial forward movement, the hollow cylinder 6 can be held by a similar flexible element 14 mounted on the barrel 1 and in contact with the hollow cylinder 6.

 Throwing system works as follows.

 The cartridge 7 with the projectile 8 and the hollow cylinder 6, brought to the stop 13, is sent through the barrel 1 to the support of its sleeve cap on the bottom of the barrel 1. The cartridge 7 is placed in the cavity of the hollow cylinder 6 at various depths. So when throwing a hollow cylinder and a projectile while ensuring a zero velocity of the projectile 8 of the used cartridge 7 relative to the speed of the hollow cylinder 6 (Fig. 1) and providing specified and variable relative speeds of the projectile 8 of the used cartridge 7 and the hollow cylinder 6 (FIGS. 2 and 4 ), the depth of placement of the cartridge 7 is equal to the length of the cartridge reduced by the length of the zone of the bottom of the sleeve, and with zero speed of the hollow cylinder 6 relative to the velocity of the projectile 8 of the used cartridge 7 (Fig. 3), the depth of placement of the cartridge 7 is equal to its full length not.

 When firing a firing pin of the firing mechanism, it punches (breaks) the cartridge 7 capsule, the cartridge powder ignites, the pressure of the powder gases cuts off the bottom section of the sleeve from its side wall along the edge of the rear end of the missile hollow cylinder 6 (Figs. 1,2 and 4) . Then, the pressure of the powder gases extends to the entire working cross-sectional area of the missile hollow cylinder 6 and from order 8, which are ejected from the barrel bore 1 with the cut-off side wall of the sleeve.

 The cut off bottom portion of the liner is ejected by a residual stream of powder gases or is freely extracted by reloading.

 When firing a shot at zero speed of the hollow cylinder 6 relative to the speed of the projectile 8 of the used cartridge 7 (Fig. 3), the pressure of the powder gases is projected 8 from the cavity of the hollow cylinder 6 as of a conventional small arms, and the fired sleeve remains in the cavity of the hollow cylinder 6, which is freely extracted by reloading.

 Thus, this device provides the use of unitary standard cartridges of any standard small arms for throwing various loads and shells of used cartridges while providing extraction of spent cartridges and the possibility of varying the initial speed of throwing loads and shells of used cartridges.

 The proposed device allows you to create a variety of weights and other devices for moving the load and the projectile more convenient and simple compared to known.

 This device is designed, manufactured in ballistic design and tested with a positive effect.
