Description

PRACTICAL SHOT.

The utility model relates to ammunition, and more specifically, to cartridges for the training of training shots during training for training personnel, in particular, to practical shots with shells for dispersing chemical reaction substances and the generation of smoke bombs when firing grenade launchers and automatic r and t x x i r

The prior art is characterized by the M407 brand cartridge for the M79 grenade launcher (see Technical Manual TM-43-0001-28, US Army Publ., 1Q, Ammunition for 40mm 1 rocket launchers, Practical ... shots section), which contains the shell of the shell rigidly fixed in it the 1-part, 1de is placed the initiating device of the blow-Hoio action, connected 1-o with the smoke-forming pieces through the detonator block located in the fragmentation case.

This shot provides the use of the design of the combat munition with minor simplifications as a practical shot having identical mass and ballistic data, which serves for visual target designation and shooting.

However, a continuation of these advantages is an inherent disadvantage of increasing the danger of a personally trained composition of a fragmented field formed by a fragmented fragment when the case ruptures, inside of the Topoio checkers are mounted smoke-generating composition.

The noted drawback is eliminated in the practical shot according to the patent RU 2138006 Ci, F 42В 8/02, i999i-., Which contains a sleeve, propelling charge and a housing with a single-part rigidly fixed in it, in which an initiating device is placed, connected with the brushes of a smoke-forming composition. Initiating devices: Bbj nojiHe is inertial, and is connected to the smoke generating compartments through a pyrotechnic moderator and an ignition unit. Smokers Checkers {)

The main part is made with an axial channel and fills the volume of the shell shell, which is equipped with a central stepped hole in the bottom part, which is closed on the side of the propellant charge cover.

The execution in the bottom part of the shell of the projectile of the outlet prevents eio crushing into fragments, since the pressure does not increase to critical values, and secondly, the gaseous products generated during the irrigation of the pyrotechnic composition of the filling flow freely behind, creating a compact volume. smoke, KOiopoe is also formed when the projectile is deepened into the root, passing unhindered through the formed channel, which improves the performance of the training shot.

The support of the lid on the step of the bottom opening of the housing during the operation of the charge prevents the breakthrough of powder gases to the smoke-forming filling checkers and their premature ignition. With a 1 increase in pressure of i-generated a-shaped products of 1-irrigation of the housing filling checkers, the lid is knocked out, freeing the bottom hole for free smoke flow.

The described invention, which is the closest analogue of the proposed design to the number of coinciding features, provides visual observation of the injured on the path of the poet along the smoke trail, which is formed after a predetermined time delay after the iipn firing, when the initiating device is decelerated, slowly igniting the filling the hull on the flight path.

A disadvantage of the technical solution is that it is undetectable. functional reliability due to the fact that smoke is a smoking pyrotechnic composition, as shown by practical tests of firing at maximum range, fully yells at the projectile's flight path until it meets the ground, which eliminates visual targeting at the point of eiu fall for subsequent shooting kirrectroniku, reducing -efficiency of training and personnel.

For example-. for a 40-mm grenade, the smoke-containing composition of the pyrotechnic checker burns out aa 15s, when firing at the maximum range until it meets the ground (OKOJSO 20s of flight), a time delay of at least s (about 1000 m flight) after firing until ignition of the shell filling checkers is necessary, which guarantees guaranteed smoke viral places

However, in this case, when firing at vertical targets set at a distance of up to 1000 m, at the minimum flying distance along the flat path (within .11 i-radii), IpaHci with a selected delay time for ignition of the filling, when meeting with a hazard. There will be no smoking, which, by definition, does not correspond to the purpose of the training shot, limiting the technological and technological possibilities for universal use.

The task underlying the present utility model is the development of a universal and training-effective university, which is effective for correcting shooting, targeting and targeting 5, having mass identical ballistic indicators identical to combat and wounded simple and functional. reliable.

The required technical result is achieved by the fact that in a well-known practical range ae, containing filled with checkers of smoke-generating 1rotechnical1 about composition with axial about i-not transmitting channel.m shell shell-, the central stepped opening of the bottom of which is covered with a lid with on the side of the propellant charge of I. and., and the initiating device in a rigidly mounted 1.O.C. part, more recently 1, is filled in the form of a Cong fusion reaction fuse, which communicates directly with the body filling, is installed on oalansirovochnom-static naoore shaio.

Directly react with 1O to the contact 1 to 1 of the detonator with a pyrotechnic smoke-generating filling of the body in the form of maiueK. equipped with an axial channel provides m1-instantaneous ignition of the last few when meeting with npei-rada: soil or target, as well as progressive burning of the checkers according to the developed internal iioBepxHocjH for intensively increasing the pressure of the gaseous products generated during UTOM, transferred to the dismantling of the central cover from a hole in the bottom of the hull.

The pyrotechnic COCTIB of filling the shell of the shell 1 when it encounters the obstacle c1 screams dynamically, which creates a compact, well visually distinguishable from 1 ozition of firing KOTOpoio smoke location serves as a guideline for correcting the O1nya.

The utility model allows to expand the technological capabilities of the training shooting modes both at maximum range and at vertical targets mounted at a distance of the plane flight path of a 1-rope with well visually distinguishable forimages. a r c o r r i r o f r i n g e s 11

Placing in a case between fuses and filling checkers a set of washers that are variable in height and weight allows the center of mass of the 1-rope to be shifted in accordance with its location in combat, execution, and rigid static fixation of the set of washers prevents imbalance on the path of 1 flight, which ensures operational balances. characteristics identical to the standard product.

C. successively, each essential feature is necessary, and their combination in a stable relationship is sufficient to achieve a novelty of quality that is not inherent in 1 signs of disunity, that is, each of the essential features is known in itself and does not differ in novelty, but the -effect of the sum is manifested in Nivian a set of essential iipiidHaKOB, which oesicates the achievement of HOBOio technical.O1o result in solving the problem (see Anisov GN about a significant newcomer, Proceedings of VNIIGPE-, vyy. 2, part 1, pp. 94-119).

The placement of the mass-washer compensator in the head of the grenade will make the body more thick-walled, strong and safe in reinforcement.

The implementation of the pyrotechnic checkers for filling the casing with the central channel provides intense smoke generation and a predetermined pressure of the products “Orenin d.chm knocking the lid out of the hole in its bottom and free flow into the atmosphere.

Placing the lid on the step of the central hole in the main part of the housing eliminates the breakthrough of powder gases burning the HO thrower into the housing and premature ignition of smoke bombs on the trajectory - and fixing it in the hole with a certain effort creates the conditions for stable yielding.

Making a central hole in the bottom of the hull, coocHOiO the channel of the checkers, ensures free flow of the generated smoke when the pyrotechnic composition of the guest body is filled, even when the burrowing of 1 rope in 1 point at the place of incidence.

The proposed practical shot is intended for training personnel in firing both from under-barrel and automatic full-time 1-rocket launchers, which is not known from the identified sources of information of the prior art, from KOTOpoiO does not explicitly follow for an ammunition specialist, but taking into account the possibility of serial production training ammunition, it is possible to make a conclusion about the response to the warrant and to the warrant of warranties.

The head part 1 with a contact variator 2 is fixed in a thick thick-walled housing 3, the bottom part of which is kinematically connected with guilty 4 by the acaca of the material of its dulce into the grooves of the housing 3.

A static oiijiaH syringing set of washers 5 is placed between the gunner 2 and body 3, which compensate for the grenade mass (metal washer) and the height of its center of mass as a whole (cardboard W: Yoami); since the mass of the contact fuses 2 is noticeably less than the mass of the initiating device with a pyrotechnic moderator in the prototype.

Inside the case 3, checkers b of a pyrotechnic smoke-forming composition with an axial fire-transmitting channel 7 are installed, and a propellant charge 8 is placed in the first 4.

The Central step hole 9 in the bottom of the housing 3 from the side of the propellant charge 8 is closed by a cover 10.

The drive belt 11 is fixed to the housing 3.

When a grenade meets an obstacle or 1point, a reaction contact detonator 2 is activated:. the energetic impulse of which MiHOBeHHO ignites the technical composition of checkers 6, which burn out internally. The increasing pressure of the generated sample, combustion products knocks the cover 10 out of the hole 9 of the bottom of the Kopiiyca 3, opening the outlet for gaseous products to the atmosphere, where a well-visible smoky cloud forms as a target indicator. 1J or the place where the wound falls. firing even when the i-rank is buried by 1 point through the channel formed by her iri atom, including the snow cover.

This ensures the versatility of the function of a practical shot on the basis of targeting at different shooting modes; both for the maximum flight range, and for vertical targets installed at different distances, where it is possible to contact with py.HiOM and the target is cohesive; repentance is steady, long.

Use of practical shots of the proposed design s having identical ballistic and inson xapaKTepHCJ4iKb 4 with live grenades; It implies to reduce the cost of training personnel personally in shooting techniques, to increase the information content of reunions, and to ensure greater safety in case of ukschiuagatsii, eliminating fragmentation and discharging.
