EXAMPLES FOR IMPLEMENTATION

Instantaneous, long-range and self-destructing instantaneous fuse consists of: a sensor for the purpose 1, a detonation mechanism 2, a self-destructor 3 and a detonator 4 (Figure 1)

The sensor for purpose 1 (FIG. 1) consists of a spring-loaded inertial body 5 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 spacer 14, slider 24 elements, such as the slider being restrained by a centrifugal safety stopper 19 (FIG. 3).

The self-destructor 3 (FIG. 2) is actuated by the piercing mechanism 9 and comprises a pyrotechnic composition 10 pressed into the 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 detonator capsule of the self-destructor, but its action can be transmitted to the output detonator only through the 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

In service 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 unrestrained position while being held by the spring;

The retainer 18 (FIG. 1) restricts the movement of the slider 14 and divides the elements of the detonation chain with its thick wall so that the accidental actuation of the detonator capsule 12 (FIG. 3) cannot trigger the detonator 4;

* · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·

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

Pyrotechnic self-destructor 10 (Figure 2) is not activated due to the stable position of the piercing mechanism 9.

At firing: At firing a grenade, respectively, the fuse is tested simultaneously by axial and centrifugal inertia 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.

On the trajectory: After leaving the barrel and after passing a certain © distance ensuring the safety of the shooter, the pyrotechnic press in the remote cocking mechanism burns, freeing up the space for moving the stopper 18 (Fig. 1) for the long cocking, which under the action of the spring 24 move and release 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 detonator capsule 12 and the detonator 4. It also clears the path of movement of the inertial body 5.

The pyrotechnic self-liquidator continues to burn gradually.

In the encounter with the target: In the encounter with the target, the inertial body 5 (Fig. 4) is displaced by the inertial forces caused by the reaction of the barrier by contracting the elastic element 13, in particular the spring, © releasing the retaining ball 6 and releasing the spring with a fighting spring 8 a battle core 7 that stabs the detonator capsule 12. The initiated detonation wave destroys the weakened section of the protective slider 14 and triggers a detonation in the detonator 4, which triggers the grenade with maximum velocity of detonation and direction from the bottom to m 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 inappropriate meeting conditions, after the expiry of the flight time, the pyrotechnic self-destructor 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 lift (displaced safety slide 14) through the weakened section of the safety slide 14, actuate the detonator 4 (Figure 4).
