The invention relates to the field of military equipment, namely to signal grenade cartridges used for the designation, control the actions of military units on the battlefield, as well as for signals warning about the possibility of any massive aggressive actions from the opposite side: massive bombing and artillery shelling, chemical attacks and the like, but can be used in signal ammunition and other weapons.

Giving signals warning is the most important task of the above and, therefore, these signals must be distinguishable for background battlefield to the greatest possible distance and should be taken at least one senses of man, but at any time of day and in any weather and climatic conditions. With regard to the signal rounds for grenade launchers, as to your portable products, triggering their element that creates a signal must occur at a fairly high altitude and be accompanied not peculiar to the battlefield sound or voice, or height, or duration and unusual visual perceptions: a large number of light sources, or multi-colored, or zone of scattering in the air, etc.

This requirement is known signal rounds for grenade launchers, described in "Jane's Ammunition Handbook Edited by Terry J Gander and Charles Q Cutshaw Ninth Edition 2000-2001" (str)do not satisfy mainly because of the possibility of the perception that they create only the signals visually. For example used by the armies of the US and South Africa cartridges M, M and M, any of which, according to the authors and the applicant of this present invention may be similar to it. Each of ammunition consists of socket and bonded with it destructible communication grenades, which contains aluminium enclosure and steel bottom that are bound to each other by sealing thinned edges of the body to the bottom. Inside grenades posted smoke charge, and at the bottom - pyrotechnic moderator, flammable smoke charge on the destruction of 15-45 m from the firing position. Every smoke charge consists of three series set channel elements, creates, in accordance with the designation of ammo either red or green or yellow smoke and burns without destroying grenades.

From the description of similar follows that it cannot be used as a warning about the possibility of aggressive actions by the opposing party at night, in fog, rain and at a fairly high altitude in the wind. Furthermore similar unmask firing position and can only be used for targeting, and that in contrast to the specific smoke colours and in the daytime, when you can distinguish the color of smoke.

Partially disadvantages of similar fixed in the American signal cartridge M for grenade launchers, described in "Jane's Ammunition Handbook Edited by Terry J Cander and Charles Q Cutshaw Ninth Edition 2000-2001" (str), which is used for signaling, targeting, and light areas in the dark and selected by the authors and by the applicant of this present invention to its prototype. The prototype consists of socket and bonded with it destroyed when the shot communication grenades in the cavity which formed aluminum housing in the form of a glass bottom and leading belt and plastic fairing, United destructible at the required height of communications posted by channel five pyrotechnic checkers installed in series and based on the bottom of the body in which lifting charge and pyrotechnic moderator, providing ignition of the explosive charge at the height 167 m

Lifting charge produces destruction due fairing with the case, the fire pyrotechnic checkers and their ejection from the chassis out as a whole, which is then through the dissemination of the combustion front of the sticks across their surfaces are separated, but random.

From the description of the prototype, you will see that it eliminated the last two drawbacks analogue. However, it cannot be used to prevent the possible massive fire attack the opposing side on the background of the coming battle, in rain, fog and snow. Additionally it acquired its additional disadvantage, namely leakage of a joint body with the fairing that the operation could lead to the ingestion grenades moisture and denial of its triggered after the shot.

The main goal of the invention is to eliminate the disadvantages of known signal cartridges, namely to ensure delivery by them of a signal, clearly visible at great distances perceived both hearing and vision, as well as improving the reliability of their work by ensuring the tightness of a joint body with the fairing.

Pursuant to the invention the solution of a technical problem is achieved by the well-known signal cartridge containing liner and bonded with it destroyed when the shot communication grenade, consisting of a body in the form of a glass with a leading band and placed in the bottom expelling powder charge and pyrotechnic moderator, calculated on the desired time delay in triggering expelling powder charge after a shot, plastic fairing connected with the building of the destroyed when triggered lifting charge communication and several series installed in the cavity grenades channel pyrotechnic checkers, the body is made of molded plastic with the open end of the outer diameters obnizhenii, the molded fairing together with the thin strip, which it is installed on diametrically outer obnizhenii housing and bonded with it with glue, it is in the cavity of the fairing and its extension mounted mechanical oscillator sound vibrations, kinetic energy is the kinetic energy of the jet of gas that is created or by the airstream, or powder gas from combustion hosted by the generator of the powder charge.

The essence of the invention is illustrated by drawings, where figure 1 shows the signal cartridge in the section.

Cartridge consists of socket 1 with a propelling charge 2 and 3 grenades, connected with pocket destroyed when the shot connectivity, such as glue. Pomegranate 3 formed case 4 in the form of glass plastic with molded bottom hole 5, attached to this port dredging 6, a leading band 7 and outer diameters obnizhenii 8 placed at the outdoor its end, and plastic fairing 9, molded together with his thin strip of 10 that fairing installed on the diametrically obnizhenii 8 enclosure 4 and connected with him glue same that binds the socket 1 and a grenade 3.

In the opening 5 housing 4 posted by pyrotechnic moderator 11, to relieve grenades at a given altitude, and in the recess of the 6 - expelling powder charge 12 enshrined thin cover 13.

In the cavity grenades 3 with a focus in her bottom 4 hosted several series installed pyrotechnic checkers 14 channel 15, cringed to the housing 4 mechanical oscillator sound vibrations, mounted in the cowling, 9 and 10 extender and use to create sound waves energy of air or gas jet.

Description of the structure and operation of mechanical generators sound vibrations that uses the kinetic energy of a gas jet, given in the book. "Ultrasound", the Small encyclopedia, ed. "Soviet encyclopedia", Moscow - 1079, str-315. In the signal cartridge truly present invention is used as intended whistle Levavasseur, allowing to use as the kinetic energy of the jet of air, created his oncoming flow, and the kinetic energy of the jet of powder gases obtained by burning in structurally the same generator propellant charge.

Considering the above the generator grenades consists of a toroidal cavity 16, made in the back of his deaf wall, clamped pyrotechnic checkers 14 to building 4. Toroidal cavity 16 contains a gap of 17 made by its large-diameter and passing into the cavity of the extension cable 10 to education between it and the wall annular nozzle 18. Side fairing 9 rear panel of the generator is equipped with a circular ledge 19, rigidly connected to the fairing 9, for example, carving. In the wall of the ring hanging 19 at the rear of the generator are executed radial holes 20, connecting it to the internal cavity 21 the ring cavity between 22 Radome 9 and circular ledge 19.

In the generator that uses the kinetic energy of the jet from RAM air, in the fairing 9 against cavity 21 are through axial hole 23, closed pasted it stub 24, which vylivaetsya internal pressure of combustion products expelling powder charge 12 and pyrotechnic checkers 14.

In the generator that uses the kinetic energy of the jet of powder gases in the cavity 21 posted powder charge in the form of checkers end of combustion and no hole 23 and thus closing it a filler bracket 24.

The work described cartridge consists in the following.

When fired, the pressure of powder gases from the combustion of propellant 2 disconnect the socket 1 with grenade 3 and accelerate the latest on the length of the barrel to the required lateral and angular speed and simultaneously set fire pyrotechnic moderator 11.

In the case of the generator that uses the kinetic energy of the jet of air from the rolling his flow, combustion products expelling powder charge 12 and pyrotechnic checkers 14 dropping the cover 24, opening a hole 23 in the fairing 9, through which they released to the atmosphere. By this moment there is a complete separation of 10 extender from the housing 4 and incoming air blows generator and, passing through it into the cavity of the extension cable 10, consistently out of it burning pyrotechnic checkers 14, forming of them even chain of lights corresponding color pyrotechnic composition checkers 14. After the release of the latest burning pyrotechnic checkers 14 from 10 extender its cavity is blown and the generator starts to sound vibrations in the form of whistling with required characteristics. With this extension cable 10 plays the role of a horn.

In the case of the generator that uses the kinetic energy of the jet of powder gases, combustion products expelling powder charge 12 and pyrotechnic checkers 14 set fire to the gunpowder bomb, located in the cavity 21 generator combustion products which blow cavity extension 10 and at the same time away from the burning pyrotechnic checkers 14, forming them straight chain of lights corresponding color pyrotechnic composition checkers 14, and the generator starts to sound vibrations in the form of whistling with required characteristics. Extension cable 10 thus plays the role of a horn.

From the description devices and work cartridge truly present invention clear that he:

- creates two types of signals (light and sound), of which at least one will always be perceived by man on the background of the field in any weather and climatic conditions;

- can also be used for targeting, management actions of military units and light areas, because it creates all the necessary factors known signal cartridges, used with the same purpose;

- the use of the generator type of mechanical vibrations in particular munition will depend on its weight and size, in mostly length;

- has higher reliability grenades, because there is no leaking joints in forming integral parts of the grenades.

Signal cartridge containing liner and bonded with it destroyed when the shot communication grenade, consisting of a body in the form of a glass with a leading band and placed in the bottom expelling powder charge and pyrotechnic moderator, calculated on the desired time delay in triggering expelling powder charge after a shot, plastic fairing connected with the building of the destroyed when triggered lifting charge, communication, and several series installed in the cavity grenades channel pyrotechnic checkers, characterized in that the body is made of molded plastic with the open end of the outer diameters obnizhenii, the molded fairing together with the thin strip, which it is installed on diametrically outer obnizhenii corps and United with him, in the cavity of the fairing and its extension mounted mechanical oscillator sound vibrations, kinetic energy is the kinetic energy of the jet of gas that is created or by the airstream, or powder gas from combustion hosted by the generator of the powder charge.
