Description

Technical field

The utility model refers to an instantaneous bottom fuze that is used in military equipment and serves as a complete set of artillery rounds for combat and training firing.

The detonator is used to activate 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 piercing 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-inductor a reaction mechanism mounted on the main charge detonation source, which receives impulse from an additional detonator cap installed in a movable sliding barrier and in an unmoved position displaced by the central axis of the fuse [1].

The technical nature of the utility model

The objective of the utility model is to create 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, while providing maximum bulletproof penetration.

The task is solved by creating a bottom fuse with instant action, protective type, 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-eliminator and a pyrotechnic stopper a mount that is kinematically coupled to a safety slide located between the detonator capsule and the detonator, and also a target sensor (firing mechanism) mounted against the capsule detonator representing a core pink with a taut spring and held in a safe position by a shotgun and an inertial body held by an 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 the length to the diameter of the detonator is L: D = 0.5: 2.0.

The advantages of an instantaneous bottom fuze according to the utility model 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 remote erection and reliable self-liquidation.

Examples of implementation of the utility model

The instantaneous, long-range, self-ejecting bottom fuse consists of a sensor for purpose 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 held by a shotgun 6 of the warhead 7, which is spring-loaded with a tensioned spring 8.

The detonating mechanism 2 (Fig. 2) consists of a puncture mechanism 9 comprising a spring-loaded 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 14, a spring 24 actuators, the slider also being retained by a centrifugal retainer 19 (Fig. 3).

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

Using the utility model

Handling. The parts and assemblies are located in a position ensuring the safety of the fuse, the capsule igniter 15 (Fig. 2) in the piercing mechanism 9 being in the unobstructed position, being held by the spring; the safety stop 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 cap 12 (Fig. 3) cannot trigger the detonator 4.

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 fired, the grenade, respectively the fuze, simultaneously experiences axial and centrifugal inertia forces. In this case, the capsule igniter 15 (Fig. 2) in the puncture mechanism 9 overcomes the protective spring and stabs at a sufficient velocity in the core 16 of the puncture mechanism, igniting the pyrotechnic press of the remote cocking mechanism 17 and the pyrotechnic press 10 of the self-destructor. the stopper 19 overcomes the spring and releases the tooth a of the guard slider 14, which is still restrained by the guard lug 18 in the remote cocking 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 capsule detonator 12 and the detonator 4. It also clears the path for the displacement of the inertial body 5.

The pyrotechnic self-liquidator continues to burn gradually.

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 pierces 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 triggers 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-destructor 3 (Fig. 1) burns and ignites the beam capsule detonator 11, which triggers the initial element of the detonation chain - the detonator capsule 12 and, subject to the presence of a lift (moved safety slide 14) through the weakened section of the safety slide 14, activates the detonator 4 (Fig. 4).
