A shot with controlled missile comprises guided shell equipped at the back section with protective pallet with obturator ring, and connected to it by means of mechanism of fixation of knock-out unit, this includes the body with capsule plug and initiation charge and knock-out charge placed in the body. On the body of the knock-out unit with long central channel pyrotechnical retarders of flame transfer are placed, those with their inlets through radial openings in the body are connected to the central valve, and with the outlets are connected to the knock-out charge. In the central channel movable piston is hermetically installed, this in initial position separates part of the cavity of the central channel adjoining the initiating charge from the radial openings and from the inlets of pyrotechnical retarders of flame transfer, respectively. This invention makes it possible to make the body of the charge with thinner walls, thus with smaller mass, and the mass of the fighting section to increase, respectively.

Description

Description of the invention

The invention relates to ammunition technology, in particular to guided missile weapons.

The famous shot ZUBK10O-1, taken as a prototype, which consists of a guided projectile 9M117 and a knockout device |1Y. The guided projectile consists of a steering drive unit with aerodynamic rudders located in the bow, a cumulative warhead, a cruise jet engine and an equipment compartment located in the tail and covered by a pallet. The projectile is connected to the knockout device by rolling the front part of the casing of the knockout device into the groove on the projectile body.

Directly in front of the sleeve in the middle part of the projectile body, a belt is fixed with a nut, intended for obturation of gases from the knockout device when launching the projectile. The knockout device consists of a sleeve in the form of a hollow steel cylinder with an inserted bottom, to which a cylindrical grid is attached. A knock-out charge is placed in the cavity between the grid and the cartridge case, and an additional powder charge is placed in the cavity between the grid and the bottom. A sleeve with a fixed piston is screwed into the central part of the bottom. An inductor and an electric igniter connected to it are fixed on the back of the pallet, which is designed to ignite the knockout charge.

The disadvantage of the prototype design is the significant mass of the engine and the hardware unit, which is caused by the thickened racks of their bodies to ensure strength under the action of the pressure of the powder gases of the knockout device due to the fact that the obturator ring is located in the middle part of the projectile body, which enters the calibrated part of the gun barrel. This circumstance, given the impossibility of increasing the mass of the projectile as a whole, does not allow to increase the mass of the warhead, that is, to increase the combat effectiveness of the projectile.

The invention is based on the task of increasing the combat capability of the projectile by increasing the mass of the warhead and ensuring the possibility of executing it in tandem. This is achieved by placing the obturator ring on the pallet, that is, on the tail part of the projectile, and reducing the mass of the engine and the equipment unit by reducing the thickness of the walls of their cases. At the same time, during the execution of the shot, the protection of the walls of the components of the projectile body against the effect of gas pressure is provided by the preliminary obturation of the protective tray located in the tail part of the projectile. This circumstance causes another problem: before the action of the knockout charge, it is necessary to first separate the projectile from the knockout device and move it forward until the obturator ring enters the calibrated part of the barrel. This task is solved by the fact that after the action of the capsule bushing and the action of the initiating charge, the projectile is separated by a special mechanism from the fastening with the knock-out device and moves forward into the calibrated part of the gun barrel. Due to the fact that special pyrotechnic flame retardants are installed between the initiating and knock-out charges, the knock-out charge is activated after a certain period of time, which is sufficient for preliminary obturation of the projectile and inclusion of its equipment. 3o Figure 1 shows a part of the guided projectile 1 with a tray 2 and an obturating ring 3 fixed to it. The guided projectile 1 in its initial state is attached to the knockout device 4, which includes: a sleeve 5 with a knockout charge b, a body 7, a capsule sleeve 8 with an initiating charge 9, a piston 10 and two pyrotechnic flame retarders 11, the outlets 12 of which are connected to the cavity for the knockout charge, and the inlets are connected by means of radial holes 13 to the central channel 14 of the body 7. The piston 10 separates from 50 the radial holes 13 from the cavity 15, which is part of the central channel 14. The device functions as follows.

From" The shot is loaded into the barrel of the gun and with the help of its mechanism the capsule bushing in the knockout device 4 is activated. At the moment of firing of the capsule bushing 8 and the ignition of the initiating charge 9, the piston 10 is in the position shown in Fig. 1, separating the radial holes 13 from cavity 15, in which the gas pressure increases. Under the action of this pressure, the piston 10 moves forward along the longitudinal channel, and interacting with a special mechanism, releases the guided projectile 1 from attachment to the knockout device 4 and - pushes it forward along the barrel of the gun. At the same time, after moving the piston, access is opened from the cavity 15 to the radial holes 13, through which the hot gases and flame enter the entrance of each of the pyrotechnic flame retarders 11, which, with a time delay, transmit the flame to the knockout charge

Gee! 20th century During the delay in the ignition of the knockout charge, the projectile has time to seal in the calibrated part of the barrel with the help of obturator ring 3. The pressure of the gases from the exploding knockout charge acts on the pallet 2 of the projectile and pushes it out of the barrel. At the same time, obturator ring C does not let gases pass in front of the pallet and protects the projectile body parts from their action.
