The detonator is used to actuate cumulative, cumulative shells, thermobaric grenades and auxiliary grenades that are part of the shots.

BACKGROUND OF THE INVENTION

A mechanical fuse consisting of a housing containing a puncture mechanism consisting of a core and a capsule igniter, which actuates a pyrotechnic stopper of the long-range mechanism and pyrotechnic charges of the self-destruct mechanism, and also a shock-inertia a mechanism mounted on the source for detonation of the main charge, which receives impulse from an additional capsuldetonator, mounted in a movable sliding barrier and in a non-elevated position, displaced from the central axis of the fuse / 1 / .

SUMMARY OF THE INVENTION

It is an object of the invention to provide an instantaneous bottom fuze for cumulative and cumulative fragmentation grenades, stabilized by rotation or non-rotation during their flight and fired by rifled and smooth-bore artillery systems, ensuring maximum cumulative penetration of cumulative penetration.

The problem was solved by creating a bottom fuse with instant action, a protective type, with long-range ejection and self-elimination, in the housing of which there is a piercing mechanism containing a core and a spring capsule igniter connected with a pyrotechnic self-ejector and a pyrotechnic stopper. According to the invention, the mechanism is kinematically coupled to a safety slider disposed between the detonator capsule and the detonator and the target sensor (firing mechanism) mounted against the capsule detonator, consisting of a spring-loaded spring and held in a safe position by a ball and retainer. elastic element. The inertial body is designed as a spring-loaded cylindrical bushing, the specific shape of the detonator has an inlet and / or outlet cumulative recess and the ratio of length to diameter of the detonator is · - = 0.5 2.0.

The advantages of an instantaneous bottom fuze according to the invention are the minimum time to activate the cumulative charge at a grenade encounter with the target, its safety in service and at firing, with applicability to both rifled and smooth-bore artillery systems with long range erection and reliable self-liquidation.

Examples of carrying out the invention

The instantaneous, long-range, self-ejecting bottom fuse consists of a sensor for the target 1, a detonation mechanism 2, a self-destructor 3 and a detonator 4 (Fig. 1).

The sensor for purpose 1 (FIG. 1) consists of a spring-loaded inertial body 5, which is held by a shotgun 6 of the warhead 7, which is spring-loaded with a tensioned spring 8.

The detonation mechanism 2 (Fig. 2) consists of a puncture mechanism 9 comprising a spring capsule igniter 15 and a core 16, a pyrotechnic delay 17 (Fig. 1) and a spring-loaded safety stopper 18, holding a spring-loaded spring 24, a spring 24

66003 B1 separating the detonating actuators, the slider being also held by a centrifugal safety stop 19 (Fig. 3).

The self-destructor 3 (FIG. 2) is actuated by the piercing mechanism 9 and comprises a pyrotechnic composition 10 pressed into an arcuate duct of a sleeve and a detonator cap 11, which is sufficiently close to the starting element of the actuating detonation chain. The detonation circuit consists of a high-sensitivity and high-speed capsule detonator 12, and a detonator 4 arranged so that the detonator capsule can only be actuated by the warhead or the self-destructor detonator capsule, but its action can be transmitted to the output detonator only through slider.

The detonator 4 (Fig. 1) consists of a detonator cup 21, a cap 22 and an explosive substance 23. The shape and dimensions of the detonator are in a certain ratio.

Way of acting

Handling. The parts and assemblies are in a position to ensure the safety of the fuse, such as:

The capsule igniter 15 (FIG. 2) in the piercing mechanism 9 is in the unobstructed position while being held against the spring;

The safety stopper 18 (Fig. 1) restricts the movement of the slider 14 and divides the elements of the detonation chain with its thick wall such that the accidental actuation of the detonator capsule 12 (Fig. 3) cannot cause the detonator 4 to actuate;

The details of the sensor for purpose 1 (Fig. 1) are blocked by the slider 14, which is held in a safe position by the pyrotechnic mechanism 2 for long-range lifting and by the centrifugal stopper 19 (Fig. 3);

The pyrotechnic self-destructor 10 (Fig. 2) was not activated due to the stable position of the piercing mechanism 9.

When fired. When firing a grenade, respectively, the fuse is tested simultaneously by axial and centrifugal inertial forces. In that:

The capsule igniter 15 (FIG. 2) in the piercing mechanism 9 overcomes the safety spring and engages at a sufficient speed in the piercing mechanism 16, igniting the pyrotechnic press of the remote cocking mechanism 17 and the pyrotechnic pressing 10 of the self-destructor 3;

The centrifugal stopper 19 overcomes the spring and releases the tooth a of the safety slide 14, which is still restrained by the safety stopper 18 in the longitudinal lifting mechanism.

The trajectory. After leaving the barrel and walking a certain distance, ensuring the safety of the shooter, the pyrotechnic press in the remote cocking mechanism burns free space for moving the stopper 18 (Fig. 1) for long cocking, which under the action of the spring 24 is moved and released the safety slider 14;

Under the action of spring 24, the protective slider 14 moves to the end position, with its weakened section between the elements of the detonation chain of the capsules detonator 12 and detonator 4. It also clears the path for moving the inertial body 5. The pyrotechnic self-destructor continues.

When meeting the goal. In the encounter with the target, the inertial body 5 (Fig. 4) is displaced by the inertial forces caused by the barrier reaction by contracting the elastic element 13, in particular the spring, releasing the retention ball 6 and releasing the combat-spring 8 7, which stabs the detonator capsule 12. The initiated detonation wave destroys the weakened section of the protective slider 14 and initiates detonation in the detonator 4, which activates the grenade with maximum velocity of detonation and direction from the bottom to the forehead. If the encounter with the target does not trigger the effect of the sensor for the purpose due to the nature of the target or the inappropriate conditions of the meeting, after the expiry of the flight time, the pyrotechnic self-liquidator 3 (Fig. 1) burns and ignites the beam capsule detonator 11, which triggers the initial element of the detonation chain detonator capsules 12 and subject to the presence of a cocking (displaced safety slide 14) through the weakened section of the safety slide 14, actuate the detonator 4 (Fig. 4).
