Examples of the invention

Frontal impact fuse with all-round action and long-range erection, consisting of a housing 1, in the front part of which are placed a membrane 9 and a protective cover 8, and in the base of the housing 1 is placed a diaphragm 2, in which a detonator capsule 34 is pressed by nut 16.

In the housing 1 of the fuse are located a safety mechanism I, placed in a shell 4 and fastened to it by a washer 5, audarnik II spring-loaded spring of the striker 14, which by means of axis 10 is kinematically connected to pendulum 6 and impact stem 7 (Fig. 1a) .

Safety mechanism I (Fig. 1a), consisting of a sleeve 3, in which are located a piercing mechanism E (Fig. 16), containing a capsule-igniter 26, spring-loaded with a spring 25 and a wire 24, a pyrotechnic stopper F, containing a sleeve 28, with extruded pyrotechnic composition 27, cup 29, spring 30, cap 31 and stopper 32, holding with spring 18 a slider 15 (Fig. 1a), wherein the detonation actuator elements of the prick capsule-detonator 33 and the beam detonator capsule are separated type 34. The slider 15 is held by a ball 17 and by an inertial double-stop mechanism G (Fig. 1c), consisting of a short-stroke stopper 19 with a spring 20 and a long-stroke stopper 22 with a spring 23, wherein the short-stroke stopper 19 is locked by the ball 21.

Impact II (Fig. 1 a), consisting of a sleeve of the striker 11, in which a pyrotechnic composition 12 is pressed and a wire of the striker 13 mounted in it, and preventing the movement of the slider 15.

Application of the invention

For business purposes: The parts and assemblies are in a position to ensure the safety of the fuse, such as:

The igniter capsule 26 (Fig. 1 b) in the piercing mechanism E is located at a certain distance from the wire 24 held in this position by the spring 25;

The pyrotechnic stopper F (Fig. 16) impedes the movement of the slider 15 (Fig. 1a), thus the prick-type detonator capsule 33 located in the slider is displaced away from the fuse axis, which determines the separation of the elements of the detonation circuit so that random

Descriptions of issued patents for inventions № 04.2 / 30.04.2019 operation of the prick capsule detonator type 33 cannot cause operation of the beam detonator capsule type 34;

The details of the inertial double-stop mechanism G (Fig. 1c) by means of the ball 17 have additionally blocked the slider 15 (Fig. 1a), which is held in a safe position by the pyrotechnic stopper F (Fig. 16), determining the long erection of the fuse;

The wire of the striker 13 (Fig. 1a) located in the composition of the striker II also prevents the movement of the slider 15, as the striker II cannot move vertically under the action of a spring of the striker 14 until the pyrotechnic composition 12 has completely burned out. , which is ignited by the piercing mechanism E (Fig. 16).

When firing: When firing the ammunition, respectively the fuse test simultaneously axial inertial forces, where:

The igniter capsule 26 (Fig. 26) in the piercing mechanism E overcomes the protective spring 25 and pierces with sufficient speed in the wire 24, igniting both the pyrotechnic composition 27 of the pyrotechnic stopper F and the pyrotechnic composition 12 pressed into the sleeve of the striker 11. (Fig. 2a);

The long-stroke stopper 22 and the short-stroke stopper 19 of the double-stop mechanism G (Fig. 2c) under the action of inertia force overcome the resistance forces of the springs 23 and 20, respectively, whereby the short-stroke stopper 19 unlocks the ball 21 and after complete settling in the sleeve hole 3 on the long-stroke stopper 22 the ball 21 rolls out unimpeded.

On the trajectory: Before stopping the action of the force of inertia, the short-stroke stopper 19 (Fig. 36) moves vertically under the action of the force of the spring 20 to the uppermost position and releases the ball 17 (Fig. 3b).

After leaving the barrel and traveling a certain distance to ensure the safety of the shooter, the pyrotechnic composition 27 (Fig. 16) of the pyrotechnic stopper F burns, freeing up space to move the stopper 32 together with the cup 29 (Fig. 3a), which under the action on the spring 30, the slider 15 is moved and released (Fig. 3b);

Prior to the combustion of the pyrotechnic composition 27 (Fig. 16) of the pyrotechnic stopper F, the pyrotechnic composition 12 (Fig. 1a) pressed into the sleeve of the striker 11 burns out, whereby the free stroke of the striker II occurs and under the action of the striker spring 14 (Fig. For), it moves as far as it will go in the pendulum 6, as a result of which the striker wire 13 does not prevent the free movement of the slider 15 (Fig. 3b);

Under the action of the spring 18 (Fig. 3b), the slider 15 pushing the ball 17 into the free space of the sleeve 3 moves to the end position, where the detonator capsule prick type 33 (Fig. 3a) stands on the axis of the fuse above the detonator capsule. beam type 34 and under the striker wire 13, which means that the elements of the detonation circuit are on one axis.

When meeting the target: When the ammunition meets the target under the action of the reaction force of the barrier at meeting angles approximately from 0 ° to 45 ° (Fig. 4a) move the impact stem 7 together with the pendulum 6 and the striker II deforming the spring of the striker 14, in which the wire of the striker 13 pierces at high speed the detonator capsule piercing type 33. At the same time under the action of high accelerations that occur when the ammunition velocity sharply decreases when meeting the target, the inertial body formed by a safety mechanism I, the shell 4 and the washer 5 are moved, which in turn also deforms the spring of the striker 14 and directs at high speed the detonator capsule prick type 33 against the core of the striker 13, whereby sharply increases the puncture energy of the detonator capsule prick type 33, respectively the sensitivity of the fuse increases when meeting the target. When the prick capsule detonator type 33 is triggered, the initiated detonation wave destroys the weakened section of the diaphragm 2 and the explosion products excite a detonation in the beam detonator capsule type 34, which initiates the main bursting charge of the ammunition.

At small angles of encounter of the ammunition with the barrier, side or other meetings of the ammunition with the barrier, regardless of the angle of encounter (Fig. 46), weak reaction and inertial forces are obtained, whereby the all-round mechanism in which they are : safety mechanism I,

Descriptions of issued patents for inventions № 04.2 / 30.04.2019 placed in a shell 4 and fixed in it by the washer 5, forming an inertial body, in the hole of which is located the striker II spring-loaded by the spring of the striker 14, pressing it through the axis 10 in the pendulum 6, supported in the impact stem 7. The inertial body rotates relative to the axis of the fuse and crawls along the support conical surface of the diaphragm 2 (Fig. 46), directing at a certain speed the already erected slider 15, in which the detonator capsule prick type 33 is placed. , deforming the spring of the striker 14. At the same time the pendulum 6 rotates relative to the axis of the fuse and crawls on the support conical surface of the housing 1, due to the inertial forces and further touched by the impact stem 7 moves the striker II, also deforming the spring of the striker 14 , wherein the striker wire 13 pierces the piercing capsule detonator type 33.
