RU206822U1 - Combined head fuse - Google Patents

Abstract

The utility model relates to the field of artillery shot fuses, in particular to combined action fuses. The stated task is achieved due to the fact that a combined action head fuse, containing a fairing and a housing, inside which a safety-actuating mechanism, an electric igniter, a detonator cap are located, contains inside the mobile unit, an electronic temporary device with built-in controller, memory, storage power converter, antenna, induction coil and contact sensor, and a short-term power supply electrically connected to the electronic temporary device, and has a normally open connection with an electric igniter connected through a pyrotechnic channel to the capsule - a detonator located in the safety-executive mechanism, the fairing is made of two parts with a dielectric insert.

Description

The utility model relates to the field of fuses for artillery rounds, in particular, fuses of combined action.

Known fragmentation-beam projectile (RF patent No. 2346230 from 03.07.2006), containing a contact trajectory fuse. The lack of a projectile - the rupture occurs after the separation of the warhead.

The closest in essence to the proposed device is the head fuse for small-caliber artillery cartridges (RF patent No. 2234051 dated 26.08.2003), which was chosen as a prototype. It contains a beam detonator capsule mounted in a longitudinal groove of the body, a deceleration device and a primer-igniter connected by means of a pyrotechnic channel with a pierced self-destruction mechanism, the axial sting of which is equipped with an inertial cocking mechanism. The disadvantage of the prototype is the lack of efficiency due to the temporary action of the fuse.

The task of the proposed utility model is to create a combined action head fuse (head fuse), which provides temporary and contact action.

The technical result consists in increasing the effectiveness of destruction due to the introduction of a head fuse of combined action into small-caliber shots.

The task is achieved due to the fact that the head fuse of combined action, containing a fairing and a body, inside which there are a safety-actuating mechanism, an electric igniter, a detonator cap, contains an electronic temporary device located inside the movable unit with a built-in controller, memory, storage power converter, antenna, induction coil and contact sensor, and a short-term power supply, electrically connected to an electronic temporary device, and has a normally open connection with an electric igniter connected through a pyrotechnic channel with a detonator cap located in the safety-executive mechanism, the fairing is made of two parts with dielectric insert.

The movable unit (not shown in the figure) consists of a short-term power supply 3 and an electronic temporary device 4, fixed inside and on the frame, respectively.

The essence of the utility model is illustrated in FIG. 1, which shows a drawing of the design of the proposed fuse.

The head fuse contains:

1 - case

2 - fairing

3 - short-term power supply

4 - electronic temporary device

5 - safety actuator

6 - electric igniter

7 - detonator cap

The head fuse works as follows.

Before operation, the head fuse is screwed into the artillery shell, then the cartridge is assembled.

In the initial state, when a cartridge is fed into the gun chamber, the fuse is programmed via a wireless interface: either via a radio frequency interface through the dielectric part of the fairing 2, or through an induction coil (not shown in the figure) built into an electronic temporary device 4. The programmed remote action time is saved into the non-volatile memory of the controller (not shown in the figure) of the electronic temporary device 3.

When fired, a short-term power supply 3 is activated under the influence of a pulsed axial load. The electronic temporary device 4 changes the initial velocity of the projectile departure using an induction coil (not shown in the figure), and adjusts the remote action time, and sends a signal to the electric igniter 6 according to the combined principle. According to the time principle - after the expiration of the programmed time of remote action, (or by contact action) - after exceeding the threshold value on the contact sensor (not shown in the figure), built into the electronic temporary device 4, indicating the event of contact with the target. After operation, the electric igniter 6 ignites the detonator capsule 7 to form the force of the flame from the detonator capsule 7.

Fairing 2 is made of conical shape and consists of two parts. The upper part is made of dielectric material, and the lower part is made of metal and has an internal thread for connection to the fuse body.

The electronic temporary device 4 consists of a controller (not shown in the figure) with non-volatile memory, a storage power converter (not shown in the figure), an antenna (not shown in the figure), an induction coil (not shown in the figure) and a contact sensor (not shown in the figure). The controller (not shown in the figure) is electrically connected to the storage power converter (not shown in the figure), the antenna (not shown in the figure), the coil (not shown in the figure), and a contact sensor (not shown in the figure) ... The electronic temporary device 4 is fixedly attached to the frame of the movable block (not shown in the figure) and is filled with a compound.

Thus, the task of creating a head fuse, providing a combined action, has been solved.
