Description

HEAD BLASTER.

A useful midsection refers to remote double-fired combined fuses, shock 1o and temporarily 1o, triggered by inertia-1 movement of mechanisms when meeting with the iipei-parade and 110 after a specified 1 time interval from the moment of the shot, determined by the combustion of the iiopoxoBoio element of the self-destruct mechanism cocking mechanism and safety device preventing spontaneous detonation of the fuse in official use 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 loading, which contains an igniter capsule and a coaxial sting of an impact reaction mechanism, an inertial cocking mechanism, a detonator radiation capsule equipped with a self-eliminating fire circuit with a safety and delay device book 23rd twin unit ZU-23, Military Publishing, M., 196ir., p. 102-103, fig. 14.3 and 14.4.

In the axial channel of the end face of the housing, which is closed by a membrane, a rod is installed by means of a centering head trap with the ability to move to the sting of the percussion mechanism mounted on a spiral retaining spring located in an annular sleeve resting on a transverse wall 11 of the longitudinal groove.

A labyrinth oiHenepe retarding deceleration sleeve closed by a protective gasket is placed between the igniter and the detonator capsule.

The disadvantages of this 1st fuse are its low functional reliability on the trajectory of the projectile to the target due to the high sensitivity of the impact1th 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 unsatisfactory protection of the beam-detonator capsule from triggering the self-destruct mechanism in official circulation in the event of accidental impacts and falling 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 the self-destruction distance.

The noted drawbacks are eliminated in the 1-tin fuse for small-caliber artillery cartridges according to patent 2205362, F 42C, 9/14, 200ii-., Containing a case in which coaxially arranged is the central rod, which presses the end of the conical fairing with the supporting head, axial stinger, igniter capsule, oi-non-transferring channel shutter with powder charge, retardation sleeve and beam-detonator capsule fuse connected 1D by pirotehnichesko1o channel nakolnym self-destruct mechanism.

A peripheral annular groove with radial inclined grooves is made in the fuse case under the conical fairing, in which the balls of the shock reaction mechanism of the axial pin are located, resting on the spiral stopper of the inertial cocking mechanism located inside the movable sleeve mounted above the annular groove of the transverse jumper { .

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

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

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

A monolithic, rigid central trap of a centrally-o-shaped rod protects the fuse membrane from dynamic loads and mechanical stresses in the power paths of the gun automatics, and secondly, it fixes the membrane rigidly from above on 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 atmospheric precipitation on the flight path and ensures the uniformity of the 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, in the event of an accidental operation of the igniter capsule, the transmission of a 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 being accidentally triggered1 when the self-destruction mechanism is cocked in official use, which increases the technological safety of the maintenance of ammunition.

This fuse works flawlessly when meeting le1 armored targets - infantry fighting vehicles, aircraft, automobiles, etc.

However, the disadvantage of a single-wave fuse is the unsatisfactory functional reliability at low projectile speeds at maximum range and maximum (up to ricochet) meeting points for the purpose of the braking reaction forces

obstruction and deformation of the conical cowling-membrane may not be enough for a dynamic forced feed of the axial sting of the sting gun and eio igniter.

In addition to Toio, the expressive transmission of O1enno1 force from the igniter capsule to the remote beam detonator capsule was not structurally ensured, which limits the time of projectile detonation, which affects the effectiveness of the eio fragmentation effect.

The objective to be solved by the present utility model is to increase the functional reliability of a tin tank in order to increase the effectiveness of the main action of ammunition.

The required technical result is achieved by the fact that in the well-known 1-tine fuse for small-caliber artillery cartridges, comprising a housing in which a central rod, an abutting conical tip of the fairing, an axial sting, an igniter capsule, a shutter O1 of a non-transferring rechargeable channel with a powder charge are inserted coaxially sequentially, and a beam-detonator capsule-detonator fuse 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 the shock reaction mechanism of the axis of the tip are located, resting on the spiral stopper of the inertial cocking mechanism, located inside the movable sleeve mounted above the ring groove of the mounting support, the coiJiacHO is fixed for an additional drummer mounted with the possibility of longitudinal movement relative to the housing in the annular groove of the mounting support, under which axial O1 non-transmission channel of the housing made receiver.

the reliability of a single-hole fuse due to the organized formation of an accelerating flame in the receiver in the axial channel of the housing, reporting the versatility of the eio shock response reaction of the forced iodine supply mechanism to the igniter capsule in all modes of projectile meeting for the purpose, thereby increasing the sensitivity and efficiency of the IO low flight speeds of shells at maximum range and maximum meeting ears with the target.

An additional impactor, in which the axial sting of the igniter capsule is fixed, increases the inertial mass, which increases the impulse of impaling for the formation of a triggering O1nevoIO force.

The reliability of the transmission of the shock impulse from the deformable conical fairing penetrating behind the barrier to the axial sting is ensured by the developed contact surface of the impactor with the pressure balls. The minimum impact of the balls is enough to force the axial tip to be supplied to the igniter capsule, that is, the reactive sensitivity of the energetic tip drive elements to inhibitory nepei arms is increased.

The receiver in the longitudinal channel of the housing under the igniter capsule serves to form a forcefully directed force, providing a dynamic start-up of the executive detonator capsule.

Therefore, each essential feature is necessary, and their combination is sufficient to achieve the novelty of quality that is not inherent in the signs of disunity, thus the technical problem is solved.

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, a 1-wave fuse in the axial channel 2 is installed sequentially from bottom to top: a beam detonator 3 of A-ЗОТ grade, safety device 4, retardation sleeve 5, shutter 6, igniter 7 and sting 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 1 of the rod 10 rigidly presses a conical fairing 12 to the end of the housing 1, under which a peripheral annular groove 13 is made in the housing 1, provided with three radial grooves 14 of the message with an axial sting 8 inclined to the longitudinal axis under yi-scrap 45 1 radii. In the grooves 14, the pressure balls 15 with a diameter of 3.5 mm are freely arranged, which together with the cowling 12 perform the functions of a shock-1 reaction mechanism when meeting with a target or a barrier.

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 16 made of a spirally twisted elastic copper tape, which is placed inside the annular sleeve 17, resting on the transverse gasket 18, overlapping the longitudinal groove 19 in the mounting support 20 under the sleeve 17 mounted in the channel 2 with the possibility of longitudinally 1o movement relative to the housing 1.

The axial channel 2 under the igniter capsule 7 is equipped with a receiver 21, below KOTOpoiO there is a shutter b mounted on the powder charge 22, fixed in the position when it overlaps the channel 2. The powder charge 22 communicates with the O1-day pyrotechnic channel 23 of the self-liquidation mechanism, including the igniter 24, spring 25, and the sting fixedly fixed under it 26.

The pyrotechnic channel 23 through the amplification charge communicates with the channel 2 below the retardation sleeve 5 (conditionally not shown in the drawing), a closed gasket 27 from above.

The safety device 4 includes an expansion chamber 28 and a gasket 29 which closes the outlet to the detonator capsule 3 from below, between which the engine 30 is mounted, which can be moved 11 more or less 1, spring-loaded with a profile bracket 31 that acts as a leaf spring. In the initial position, the engine 30 blocks the axial channel 2, that is, access to the detonator capsule 3.

The fuse operates as follows. At the time of the shot, under the action of inertia forces from linearly accelerating the projectile in the barrel bore, the guns 17 and the igniter 24 of the self-destruction mechanism move down. In this case, the sleeve 17 penetrates the gasket 18 and is installed in the groove 19 of the mounting support 20, releasing the spirally twisted tape of the stopper 16, and the igniter capsule 24, compressing the spring 25, impinges on the sting 26, igniting the pyrotechnic composition of the labyrinth of the Hoio channel 23 and nopoxo 22 shutter 6.

Under the action of centrifugal forces of rotation of the projectile, the stopper tape 16 is untwisted, releasing the stops of the striker 9, insignificant axial sting 8, and the engine 30, squeezing the bracket 31, moves to the periphery of the chamber 28 and releases the inlet of the channel 2 of the safety device 4.

The stopper tape 16 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.

opens and releases the shutter 6, which is moved by the centrifugal forces of rotation of the projectile to the periphery, opening the axial channel 2. When the atom of energy is partially leaked into the axial channel 2, there are not enough basic or solid particles to burn through the gasket 27 of the sleeve 5.

The actuator cocked cock and he is ready to go.

When meeting with the target 1 trap 11 of the rod 10 and the fuse housing 1 penetrate through the thin-walled iipei rad, the 1-cone fairing 12 is spatially deformed and crumpled along the profile of the housing 1. In this case, the conical fairing 12 dynamically radially overcomes the void of the annular groove 13 and transfers shock impulse 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 moving striker 9, increases the reliability of the operation of the igniter 7, including the limit, to rebound, meeting at the maximum flight range at minimum speed.

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.

Powder chases and solid particles of the products of rhenium pyrotechnic composition of the igniter capsule 7 are accumulated in the receiver 21, which then flow out from the throttling 1st output axial channel 1 of the device 2 in the form of a force of flame.

The OiHCBOH pulse from the flue-igniter 7 is transmitted through channel 2, 11 the gasket 27, through the sleeve 5, the open safety device 4, and then, the 11th gasket 29, to the beam detonator capsule 3, which is triggered, initiating a bursting charge of the projectile.

In the case when the projectile does not meet the target at a distance of 4 km, the pyrotechnic charge in channel 22 lasts for 15 s. after the shot C1 rises. The gaseous products of C1Orania enter the bushing 5 of channel 2, and then they accumulate in the expansion chamber 28, 1de, burn the gasket 29 and, with a directed stream, go from the outlet 1 of the channel 2 of the safety device 4 to the detonator capsule 3 - the shell self-destructs.

In cases that are possible during official handling, once the capsule igniter 24 is inertially impaled by unauthorized shocks and falls, or ignites in the chamber and power paths of the automatic gun from overheating, for example, when the firing is stopped, the radiation pulse from the fire chain of channel 23 to In this case, the detonator capsule 3 will not be received, because the output of the safety device 1 of the device 4 is blocked by the engine 30, 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 dusty air, raindrops, hail and solid aerosol particles ricochet from the conical surface of the fairing 12, significantly reducing the impulse to 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 axially 1 sting 8.

Bceuoi-one and universal is ground-based unarmored equipment and enemy manpower at a range of up to 4 kilometers, as well as air targets at altitudes up to 2000m and oblique range up to 2500m.

According to a comparative analysis and a technical solution with identified analogues of the prior art, from which the invention does not explicitly follow for a specialist of 110 ammunition, showed that it is not known, and taking into account the possibility of serial production of a single-volley fuse, it can be concluded that the criteria for patentability are met.
