Description

HEAD BLASTER,

The utility model relates to double combined action fuses, shock and temporarily, triggered by inertial movement of mechanisms when meeting with iipei rada, but after a predetermined period of time from the moment of firing, O11 is determined by the combustion of iiopoxoBoio of the self-destruction mechanism element containing a spring cocking mechanism and a safety device preventing spontaneous detonation of the fuse in official circulation and at a distance.

The state of the art in this area is characterized by a MG-25 single-fuse fuse for small-caliber artillery cartridges of unitary Io loading, which contains a kaisul-igniter and a coaxial sting of an impact reaction mechanism, an inertial cocking mechanism, a beam detonator capsule, equipped with an O1 left-handed circuit with a safety and delay device book 23-mm twin unit ZU-23, Military Publishing, M., 1961., p. 102-103, fig. 14.3 and 14.4.

A rod is installed in the axial channel of the end face of the enclosure closed by a membrane with a means for centering the trap rod, which can be moved to the stinger of the shock mechanism mounted on a spiral retaining spring placed in an annular sleeve resting on a transverse partition of the longitudinally groove.

Between the igniter capsule and the detonator capsule there is a labyrinth oi non-transfer retardation sleeve closed by a protective gasket.

The disadvantages of this fuse are its low functional reliability on the trajectory of the projectiles to the target due to the high sensitivity of the shock mechanism triggered by rain, rain and dust, from mechanical stresses on the end membrane in

the gun’s power supply paths, as well as the inadequate protection of the beam-detonator capsule from triggering the self-destruct mechanism in official circulation in the event of accidental impacts and falls or from ignition during overheating in the power supply paths of the artillery systems automation, especially during stops between firing lines.

In addition to Toio, the design of the labyrinth retarder determines the technological complexity of manufacturing in serial production using high-precision unique equipment, and also limits the range and range of self-destruction distance.

The noted drawbacks are eliminated in the analogue 1a chosen as the closest one, by the number of matching features and technical nature, a holovy fuse for small-caliber artillery cartridges according to patent 2205362, F 42C, 9/14, 2001i., Containing a housing in which the central rod is coaxially arranged, the conical fairing end that presses with the support trap, axial stinger, igniter capsule, O1 shutter channel with powder charge, retardation sleeve and beam-detonator capsule fuse, connected by means of a channel pirotehnichesko1O nakolnym self-destruct mechanism.

A peripheral annular groove with radial inclined grooves is made in the fuse case under a conical radome. in which the balls of the impact reaction mechanism of the axial sting located on the spiral stopper of the inertial cocking mechanism located inside the movable sleeve mounted above the annular groove of the transverse jumper (mounting support) are located.

In the well-known inertial-reaction 1-fuse, the main service characteristics of the destination are improved when used in small-caliber cartridges but with the cocking range of the self-destruction mechanism and the expansion of the range of the eio response distance.

at the same time, the safety in the official handling and operation of cartridges is increased.

This fuse is all-inclusive, that is, the given discontinuous action on the trajectory does not depend on the state of the atmosphere.

A monolithic, rigid, 1-pole central-angled rod protects the fuse’s membrane from dynamic loads and mechanical influences in the power paths of the gun’s automatics, and secondly, the membrane is rigidly fixed from above to the body.

The conical shape of the membrane, made in the form of a fairing, reduces the sensitivity of the shock mechanism to the effects of precipitation on the flight path and ensures all-round use of the fuse.

The membrane of the primary part of the body, which is deformable when meeting for the purpose, performs the functions of the impact drive of the movement of the balls along the inclined radial grooves to the axial pruning tip.

A transverse shutter equipped with a powder stopper in the axial deceleration channel prevents the accidental operation of the igniter capsule and the transmission of the radiation pulse to the detonator capsule and premature projectile rupture.

An additional mechanism for protecting the inertial action from the centrifugal forces of rotation of the projectile prevents the detonator capsule from accidentally charging the self-destruct mechanism in official circulation, which increases the technological safety of the maintenance of ammunition.

This fuse works flawlessly when meeting with armored targets - infantry fighting vehicles, aircraft, automobiles, and so on.

However, a continuation of the advantages of the well-known detonator is the inherent lack of unsatisfactory sensitivity of the reaction mechanism when meeting with small obstacles: snowy infusion, water surface or loose i-pryat, which reduces the effectiveness of the damaging effect of ammunition, as. there may be cases where the igniter capsule is not pricked by an axial sting, for the movement of which the deformation of the conical fairing from external forces is not enough for iipei-rada to work.

The objective of which the present utility model is directed is to increase the functional reliability of a 1-wave fuse to increase the efficiency of the OCHOBHOI-O and the exciting effect of the ammunition.

The required technical result is achieved in that in the well-known 1-tine fuse for small-caliber artillery cartridges, comprising a housing in which a central rod, an adjacent cone-shaped end face, an axial stinger, an igniter capsule, an O1 non-retardant charge channel with a pore are inserted coaxially in series and a fuse for a beam detonator capsule connected by means of a pyrotechnic channel with a self-eliminating firing mechanism, while in the housing a peripheral annular groove with radial inclined grooves is made with a conical fairing, 1de balls of an impact1 reaction axial stinger mechanism located on an inertia1O cocking mechanism located on a spiral stopper mounted above an annular groove of a mounting support, according to the invention, the central shaft is equipped with a central rod a communication channel through the through windows of the housing with a peripheral annular groove under the conical fairing.

Distinctive features ensured an increase in functional reliability to a single-fuse fuse, reporting the versatility of the action of the reactionary-1 axial sting mechanism when projectiles encounter obstacles of different stiffness.

The longitudinal channel and, centrally, the rod through the through windows communicates with the annular groove of the housing, which provides direct interaction of 1pipe, water or CHeia, breaking through the end membrane, with pressure balls, bypassing the conical fairing.

At the same time, the material of the barrier inside the communication channels is compacted, which concentrates the force on the balls to move the axial tip, as a result of which the probability of fuse operation has increased markedly.

Therefore, each essential feature is necessary, and their combination in a stable relationship is sufficient to achieve the novelty of quality that does not depict the features in disunity, that is, to solve the technical problem.

According to the comparative analysis of the proposed technical solution with the identified analogues of the prior art, the invention for the ammunition specialist does not explicitly follow from KOTOpoio, that it is not known, therefore, taking into account the possibility of industrial serial production of a cold fuse, it can be concluded that the patentability criteria are met.

The essence of the utility model is illustrated in the drawing, 1de is depicted; on fi1.1 - 1-tailed fuse in the context; figure 2 is the same cocked position.

The utility model is illustrated by an example of a fuse for an artillery 30-mm cartridge for a 2A42 automatic gun.

In case 1, 1-wave 1O of the fuse in the axial channel 2 is installed sequentially from bottom to top: a beam detonator 3 of the A-ZOT brand, safety device 4, retardation sleeve 5, shutter 6, the igniter 7 and the tip 8 fixed in the hammer 9, and on the front end of the housing 1 is fixed to the Central rod 10 with the support 1OVOLOVA 11.

The head 11 of the central 1O rod 10 rigidly presses a conical fairing 12 to the end of the housing 1, the iodine of which and the housing 1 are provided with a peripheral annular groove 13, provided with three radial communication channels 14 with an axial tip 8 inclined to the longitudinal axis of the iiJioM 45 1-radar iodine. In the grooves 14, pressure balls 15 with a diameter of 3.5 mm are freely arranged, which together with the cowling 12 act as a shock reaction mechanism when meeting with a target or iipei-rada.

In the central rod 10, a longitudinal communication channel 16 is made with a peripheral annular groove 13 through the through holes 17 of the housing 1. A membrane 18 is mounted in the trap 11 of the rod 10, which overlaps the channel 16.

The tip 8 in the axial channel 2 of the housing 1 in the upper initial position by means of the hammer 9 is held on a coaxial safety stopper 19 made of a spirally twisted elastic copper tape, which is placed inside the annular sleeve 20, resting on the transverse gasket 21, overlapping the longitudinal groove 22 in the mounting support 23 under the sleeve 20, mounted in the channel 2 with the possibility of longitudinally moving about the housing 1.

The axial channel 2 under the igniter capsule 7 is equipped with a receiver 24, below the KOTOpoio there is a shutter 6 mounted on the powder charge 25, fixed in the position when it overlaps the channel 2. The powder charge 25 communicates with the ocher pyrotechnic channel 26 of the self-destruction mechanism, including the igniter 27, preloaded spring 28, and the sting 29 fixed under it.

Pyrotechnic channel 26 through an amplifying charge communicates with channel 2 below the retardation sleeve 5 (conventionally not shown in the drawing), a top-closed gasket 30.

py 31 and from below the gasket 32 closing the exit to the detonator capsule 3, between which the engine 33 is mounted with the possibility of lateral movement, spring-loaded with a profile bracket 34 acting as a leaf spring. In the initial position, the engine 33 overlaps the axial channel 2, that is, access to the detonator capsule 3.

The fuse operates as follows. At the moment of the shot, under the influence of inertia forces from linearly accelerating the projectile in the bore of the barrel, the guns 20 move downward along with a 1-shot igniter 27 of the self-destruction mechanism. After this, the sleeve 20 moves around the gasket 21 and is installed in the groove 22 of the mounting support 23, releasing the spirally twisted tape of the stopper 19, and the igniter caps 27, compressing the spring 28, impinges on the sting 29, igniting the ignition of the pyrotechnic composition of the Hoio channel 26 channel and nopoxoBo 25 shutter 6.

Under the action of centrifugal forces of rotation of the projectile, the stopper tape 19 is untwisted, releasing the stops of the striker 9, bearing the axial sting 8, and the engine 33, squeezing the bracket 34, moves to the periphery of the chamber 31 and releases the inlet of the channel 2 of the safety device 4.

The stopper tape 19 is completely untwisted at a distance of 1.53.0 m of the flight distance, releasing the axial sting 8, inertially pressed to the grooves 14 of the housing 1, which 1 guarantees to hold the sting 8 in its highest position. Balls 15 under the action of centrifugal forces of rotation of the projectile adjacent to the fairing 12.

Further, at a distance of at least 20 m flight and 1 guaranteed up to 100 m (according to the tactical and technical requirements), the powder charge 25 burns out and releases the shutter 6, which is moved by centrifugal forces of rotation of the projectile to the periphery, opening the axial channel 2. When the atom is partially leaked into the axial channel 2 1 hot gases and particulate matter are not enough to burn through gasket 30 of sleeve 5.

Fuse actuators are cocked and he is I-OTOB to work.

When meeting with the target 1 trap 11 of the rod 10 and the fuse housing 1 penetrate through a thin-walled upei-rad, the 1 cone fairing 12 is spatially deformed and crumpled by the profile of the housing 1. When the atom is dynamically radially, the conical fairing 12 overcomes the void of the annular groove 13 and transmits a shock pulse adjacent balls 15, which dynamically move along the inclined grooves 14 to the center, pushing the drummer 9 with the sting 8 along the axial channel 2 until the last meeting with the igniter 7 and pricking eio.

The additional mass, together with the stinger 8 of the driving axis of the striker 9, increases the reliability of the operation of the igniter 7, including the limit, up to rebound, at the maximum range.

In this case, the tip 8 dynamically receives an impulse of working movement through the hammer 9, which has a developed contact surface with the pressure balls 15, which ensures their inevitable interaction for the forced supply of the tip 8 to the igniter caps 7. This increases the functional reliability of the fuse and ammunition as a whole .

Gunpowder gases and solid particles of the products of rhenium pyrotechnic composition of the igniter 7 are accumulated in the receiver 24, which then flow out in a form of a force of flame from the throttling output / axial 1O channel 2 of the device 4.

The one-day impulse from the igniter capsule 7 is transmitted through channel 2, burning the gasket 30, through the sleeve 5, the open safety device 4, and then, the living gasket 32, to the radiation detonator capsule 3, which is triggered, initiating a gap8.

.

NOI projectile charge.

When the projectile hits on loose soil, water, or in the sun, the cowl 12 is not guaranteed to be deformed to create the required shock impulse to move the balls 15. In this case, the dynamics of the horseradish material are used, which, through the longitudinal channel 16 of the central rod 10, penetrates through the windows 18 17 into the peripheral groove 13 of the housing 1 under the fairing 12. The barrier material fills the groove 13 and, being compressed, pushes the balls 15 out of the inclined grooves 14. Next, the above actions occur.

In the case when the projectile doesn’t meet the target or the obstacle at a distance of 4 km, the pyrotechnic charge in the channel 25 for 15 s. after a shot burns out. The gaseous products of С1orania enter under the sleeve 5 of channel 2, and then they accumulate in the expansion chamber 31, 1de, burn the gasket 32 and with a directed stream from the outlet1 of the opening of the safety device 1 go to the detonator capsule 3 - the shell self-destructs

In cases that are possible during official handling, when the capsule igniter 27 is inertially punctured during unauthorized shocks and falls, or ignites in the chamber and power paths of the automatic gun from overheating, HanpjtMfA when the gun stops firing, then the radiation pulse from the O1 circuit of channel 26 to the detonator 3 at this will not happen, because the output of the safety device 4 is blocked by an engine 33, which is cocked only under the action of centrifugal forces on the flight path of the rotating projectile.

When shooting in conditions of atmospheric precipitation and dustiness of the air, raindrops, hail and solid aerosol particles ricochet from the conical surface of the fairing 12, which significantly reduces the momentum on the pressed balls 15, which are loaded with centrifugal forces of rotation of the projectile, which prevents their movement to the center, excluding interaction with drummer 9 sting 8.

The fuse of the proposed design is intended for use in the assembly of unitary cartridges with high-explosive fragmentation and fragmentation tracer shells designed to combat ground unarmored equipment and enemy manpower at a distance of up to 4 kilometers, as well as air targets at altitudes up to 2000 m and oblique ranges up to 2500 m , is all-terrain and versatile.
