Description

ARTILLERIAN LOW CALIBRATION CARTRIDGE.

The poleanaya model refers to ammunition, and more specifically to ammunition, small-caliber artillery cartridges of unitary loading.

The unit of technology in this field is characterized by unitary mass ammunition cartridges for automatic guns described in patents RU 2095735 and 2095736-, F 42В 5/02. 1997 , which contain a projectile and shell 5 including a bulk propellant propellant charge and a kaasyul-Bosilamenitel installed in its bottom, communicating by means of a stoyenenoch channel, which has broadening.

By the number of coinciding features and technical nature, the closest analogue to the proposed cartridge was the small-caliber artillery cartridge according to patent RU 2095736 F 42В 5/02, i997i., In which, ignition of the powder propellant charge was almost the entire volume from the center, O1 neperen. Used from the bottom 1 capsule -Igniter tube diameter ignition hole Ailsa and a length of 0.3-0.5 of its height. The channel of communication of the bottom iO igniter capsule with a propellant propellant charge has a broadening, which acts as a receiver, 1) The pressure of the chase-condensed products of rhenium increases and the igniter force forms.

In order to increase the initial velocity of the projectile in the present invention, the formation of a high-temperature erytohenium powder mixture of a propellant charge is increased by additionally introducing optimized Ieometric parameters into the composition of high-energy aluminum plates.

Organizing with the help of an O1 transfer tube uniformly central bHoio ignition of a propellant charge ensures equalization of the pressure of the formed powder gases in the volume of the cartridge, which 1-guarantees stable intra-allistic characteristics to the noun, “.................... ., -.- 12V / O2

jia and an increase in the initial velocity of the projectile.

However, the shortcomings of the original OO cartridge are a continuation of the eio advantages. Placing inside the O1 limited volume of the sleeve of the flame tube reduces the mass of the iiopoxoBoio propellant charge, the re-compaction of which makes it difficult to ignite when equipped. The elevated temperature of the 1Orenia is highly energetic combined with the composition of the propelling charge containing aluminum plates, approaching the maximum, which reduces the survivability of the barrel and the details of the gun automation.

The selection of the constituent components of the propellant charge oipa industrializes the use of the known cartridge in serial production.

In addition to TOio, the operation of the cartridge is known to be unsafe, because the working pressure developing in the cylinder in the range of 4000-4500 k1 / sq.cm, the igniter caps reinforced by punching at the end can be knocked out into the gun’s bolt, where Iazo-condensed products of C1orania metathe. charge, causing irreparable mechanical and thermal damage.

The task underlying the present utility model is to simplify the technological design of the cartridge and increase the functional reliability of the efficient ignition of the powder in the volume of the propellant charge and the safety of operation.

The required technical result is achieved by the fact that in the well-known artillery small-caliber cartridge containing an interconnected projectile and 1 cartridge 5 comprising a bulk powder propellant charge and a bottom igniter capsule communicating via a channel with broadening, according to the invention, the igniter capsule is mounted on a housing equipped with an axial bore , filled with a 1O intensifying igniter charge and fixed in a glass-shaped obturating shell with a damping pad at the bottom and top its end face is avaltsonan on a bowl-like lid fitted with a central window mounted in the housing with the possibility of movement, the shell being installed in a channel broadening made from the end of the sleeve, which has a radial groove.

Placement on the anvil with an axial hole reactively initiates, when fired, an igniter and pulse forming a calibrated sharply-adjusted 1O force to ignite the intensely charged charge of the body, which ensures the required functioning and calculated 1-by-minute ignition of the propellant 1 charge.

Strengthening the body, which is a small igniter capsule, in a glass-shaped obturating shell, helps to prevent the breakthrough of one-shaped products of the throwing of a propellant charge into the gun automatics.

The obturating shell of a simple and technologically shaped glass, which is mated during assembly with the body, by a factor of 1 increased the mechanical strength of the ignited device, forming a single supporting structure with a thickened bottom of the puff structure.

The installation of a damping pad between the bottom of the shell and the bottom of the body, in a dynamically loaded section, protects the igniter capsule from mechanical damage. It destroys the impact of the hammer of the automatic firing, 1 strike energy at 1 interface of the multilayer transverse structure and ductility of the gasket material.

Mounted with the possibility of axial axial movement relative to the housing, a creep-shaped crack placed over an amplifying ignition charge is out. plunger functions. ny mechanisms and additional elements.

Secondly, the O1da housing with the lid is telescopically opened, in place of the fastening elements, a volume is formed, forming a receiver, which additionally increases the volume, where the potential energy is accumulated for a more thermo-dynamic thermo-dynamic conversion of the irrotechnical composition into an ignition pulse that breaks through without interruption the hole of the bottom channel of the canister is transmitted almost over the entire length of the propellant propellant charge and ensures simultaneous replacement of eio from the inside.

These design features and their interaction in the dynamics of the initiation of the shot increase the reliability of ignition and the stability of the combustion of propellant powder, thereby improving the ballistics of the projectile.

An additional lock fastening of the hull cover by filling the end face of the obturating shell provides a concentration of energy of rhenium of the amplifier charge for more dynamic ignition in the entire volume of gunpowder of a well-charged charge of shell 1, which contributes to an increase in the initial velocity of the ammunition and its flight range.

Placing and broadening stepwise about the channel at the end of the bottom of the liner ensured the assembly of the proposed design more efficiently ignited the device, distorting the O1 transfer tube and thereby freeing up the volume of the i-cartridge for additional metate powder. 1 only 1 charge, while the receiver functions cup-shaped lid movably mounted in the housing.

The widening of the stepwise channel of the bottom channel 1il.za of the radial groove provides reliable mechanical fastening of the supporting shell in it, which is plastically deformed by the pressure of powder elements in the housing when the amplification charge is collected, which prevented 4

Protects unacceptable embroidering on the device in the shutter.

The invention has simplified the design of the cartridge, and its distinguishing features are an increase in the functional reliability and efficiency of the ocHOBHOio designation, which improves the ballistic characteristics of the ammunition,

The new relationship of the proposed structural elements with the well-known new quality igniter device. You 1O-1 nyayuschy additional functions:

- obturation, and hermetic locking of the volume of the ailza during the vent;

-slow-motion formation of a highly energetic heat pulse. is transferred in the center along nopoxoBOiO propellant charge of increased mass, providing its ignition in volume, intense and stable 1 rhenium.

The proposed design is more universal in the possibility of using pyrotechnic compositions of an igniter capsule different in sensitivity and energy and an amplifier igniter charge.

Consequently; each essential sign is necessary and their combination in a stable relationship is sufficient to achieve a novelty of quality that is not inherent in signs of disunity, that is, not the sum of the effects is obtained, but the sum effect when solving the technical problem.

The essence of the utility model is illustrated by the drawing, which has a purely purely valid purpose and does not limit the scope of rights of the fochsmule;

on fi1.1 - artillery small-caliber shot; in FIG. 2 - igniter, type A on phi1-.1; on fi1.3 - the same when triggered.

structurally includes a composition of a 1-fuse fuse i, a shell 2 of a projectile containing 3 explosives, a lead device 4 and a tracer charge 5, and 1 cartridge b, in the bottom of which is mounted an ignition device 7 filled with a powder propellant charge 8, which interacts with tracer charge 5 shell 2 shells.

The proposed ignition device 7 includes {fi1-.2) a cylindrical body 9 in the form of a glass, combined in the bottom with anvil 10, which form two chambers 11, 12 upper and lower, respectively. In the lower chamber 12, there is mounted 11 a laminator 13 containing a rod 14 with an impact-ignition composition 15, and the upper chamber 11 is filled with an amplification ignition composition of an irrotechnical charge 16

The anvil 10 is equipped with a central firing hole 17 directly connected to the igniter capsule 13.

The charge 16 is covered from above with a sealing foil 18, on which a cup-shaped lid 19 with a central exit window 20 is mounted, which is mounted with the possibility of axial movement relative to the housing 9 during operation, being its telescopic approach.

The casing 9 is placed in a watertight shell 21, made in the form of a glass, between the massive bottom of which and the bottom of the casing 9 a damping pad 22, a brass plate, is installed.

The upper end of the shell 21 is rolled through the upper end of the casing 9 to the cover 19, thereby performing geometric and force closure of all structural elements described in the IO igniter of the device 7 and forming it as an autonomous product for storage and transportation for picking when assembling cartridges, preferably small-caliber artillery.

the channel channel of the bottom of the sleeve b into the tension 1-shell 21 and the aperture hole 24 communicates with a propelling charge 8 of the sleeve b. On the lateral surface of the broadening 23, approximately in the middle, a radial groove 25 is made with a depth comparable to the depth of the wall 21.

The matron operates with the proposed recovery 11-1 replacement device 7 as follows. When fired by a striking gun, the cap 14 of the igniter capsule 12, reactively deformed, dynamically moves the impact-ignition composition 15 based on lead trinitresorzinate (TNRS) to the anvil 10, which is both strong and strong. me.

On the surfaces of the damping plastic gasket 22 (the chambers of the separation of the layered structure of the bottom, the igniter 1 of the device 7) is extinguished; the impact energy of the striker, which prevents the mechanical breaking of the bottom of the shell 21 and the sealing of volumes of the igniter 7 and shell b with propellant powder charge 3.

Concentrated in the center of the force of the flame from the composition 15 directly 11 is transmitted through the axial hole 17 of the anvil 10 to the pyrotechnic amplifying charge 16, igniting eio.

The proposed design ensures the normal functioning of the shot with a technical heterogeneity of propellant propellants 8 in terms of the dispersion of thermophysical characteristics depending on the charge density, nitrogen content and flechmatization of the composition, grain shape, size and porosity, etc., by varying the thermal pulse power of the igniter capsule 12, for example , the choice of type of flash-ignition1o composition 15.

Thus, the temperature of the thermodynamic process of the explosive transformation of alternative composition 15 based on TNRS is lower than that of the first compound, but the first one is kept at a temperature of up to 80 ° C, radionuclide as the second, more sensitive - not higher than 50 g-DU-ohm C, which expands the selection and application area 1,

It should be noted, that with the bar-shaped tool, the volume ratio of both chambers 11, 12 of the body 9 is varied. As a rule, 1 of the device 7 is controlled by adjusting 1 stamping depth and bottom thickness of Kopiiyca 9 and anvil height 10. This allows you to change the charge mass 16 in chamber 11 accordingly for adapting various pyrotechnic compositions.

By increasing pressure of 1 gaseous products of 1 Orehenium 1G charge 1G, cover 19 moves along the body 9 and expands, rolling the end face of the shell 21, until it stops at the landing step Io of the broadening 23 of the channel in the bottom part of the sleeve b, while sealing its volume and, c. for example, the volume of the sleeve, and the case 9 together with the shell 21 are radially deformed into the free volume of the groove 25, making a lock connection due to the geometrical closure of the oboje 21 with the sleeve b, which prevents axial movement of the device 7 backward.

The igniter 7 is jammed in the cylinder G, and

the solid bottom of the ei-o shell 21 i-hermetically isolates the volume of the liner b.

In this case, a receiver 26 (phi1.3) is formed above the charge 16, in which 1-like products of rhenium pyrotechnic composition of the amplifying charge 16 are slowly accumulated, coming through the output window 20, which is free of by-by-by-by-bye by the way 18.

The cup-shaped lid 19, axially moving under the action of increasing pressure in the chamber 11, performs the telescopic function of Io Kopiiyca 9, dynamically forming an obturation of the cartridge 6 preventing breakthrough of the powder guns and the gun’s shutter, and forms the receiver 26, increasing the volume of the chamber 11 to accumulate the potential energy of the expressively directed force in the center is throwing 1o nopoxoBOio of charge 8 of i-cartridge 6, which yields faster in volume, which is guaranteed to be set8.

The first mode is “nopoxoBOio filling 3” and the required meta. imiuls boeirias, telling him the estimated initial speed.

The thermal burning energy of the propellant charge S ignites the tracer charge 5 of the housing 2, the 1-azo-condensate phase of the prototype additionally increases the propellant momentum.

The positive results of the tests of the pilot batch of 30 mm artillery cartridges with the igniter device of the present invention, in which the grades and mass of the pyrotechnic compositions varied, confirmed the stability of the obtained aerodynamic characteristics of the shells. The product is recommended for arming.

A comparative analysis of the proposed design of the artillery cartridge with the identified analogues of the prior art, from KOTOpoio explicitly, the utility model does not follow for the ammunition specialist showed that it is not known, and given the possibility of industrial production, it can be concluded that the criteria are met patentability.
