The invention relates to the field of military equipment, ammunition nonlethal actions, namely the signal-lighting mines intended to indicate the appearance of the enemy and light areas on the installation location of the mines.
Known signal flare munition (U.S. patent No. 4976201 published 11.12.90 year).
The ammunition consists of a housing, which houses the main pyrotechnic composition to provide light and sound effects and the fuse, between which is placed lifting charge, separated from the pyrotechnic composition diaphragm having a Central hole, filled retarding composition.
The disadvantage of this weapon is the only one lighting charge, which reduces the time of illumination.
Known cluster signal flare munition (U.S. patent No. 5359918 published 01.11.94 year).
Ammunition is a multi-level framework of cassettes. The cassette consists of three tubes arranged in a row. Each tube is light, igniter and push charges. Eject the charge is activated from the electric igniter.
The disadvantage of this charge is the presence of an electronic circuit of the ignition delay.
Also known signal flare munition (French patent No. 2353825 published 03.02.78 is.), selected as a prototype to declare, because it is the closest analogue to the problem at hand and the number of similar features.
The munition includes a body in the form of a shell, inside of which along the axis of the munition each other placed a number of lighting charges, each lighting battery has a lifting charge to propel the previous lighting charge placed under it, the host serial trigger explosive charges mounted on the axis of the munition eject the charge fuse, a firing circuit connected to the expelling charge fired in the first place. The host serial trigger explosive charges is a serial chain of devices, providing with a given time delay ignition of the subsequent lifting charge.
The disadvantages of this signal light munition is consistent placement in the same housing one above the other lighting charges with a time delay device, which leads to an increase in the length of the body and reduce the reliability of operation by increasing the number of elements of the firing circuit.
The task in this field of technology is the development of signal-lighting ammunition, allowing you to signal the emergence of the enemy and for a long time the OS is esati the installation position of the ammunition after it has been enabled.
The technical result of the claimed signal light munition is to increase the efficiency and reliability enable lighting charges.
Additional technical results that may be obtained from the use of the claimed invention are improving usability by reducing overall performance and fire safety when firing ammunition.
Specified the claimed technical result is achieved due to the fact that in the known signal flare munition, comprising a housing defined therein illuminating and relevant to them, placed them under expelling charge, eject the battery fuse, placed along the axis of the munition and associated firing circuit directly with expelling charge fired in the first place, and the host serial trigger explosive charges, what's new is that the lighting and the respective explosive charges are placed on a circle around the ejector charge fuse in it openings on the device. The host serial trigger explosive charge consists of the base, one side of which is made annular groove with branches, which number corresponds to the number of especializados, and the other side adjacent to the casing by placing explosive charges. On end parts of the branches are made of through-holes aligned with the holes of the case, where are lifting and lighting charges. Lots of branches adjacent to the annular groove, in addition to the plot, transmitting a firing pulse explosive charge fired in the first place, is made larger than the ends and provided with a gear charges, made of pyrotechnic composition, and the annular groove is filled retarding pyrotechnic composition. The firing circuit connecting eject the charge of the detonator and explosive charge fired in the first place, additionally contains a plot with immediate pyrotechnic composition and transfer charges, in addition to the charge transmitting a firing pulse to lifting charge, triggered primarily made of a height less than the height of retarding composition of the ring groove.
The placement of lighting and their respective explosive charges on a circle around the ejector charge fuse in it openings on the device allows you to optimize the dimensions, i.e. the beneficial use of the volume of the body of the munition. Moreover, such an arrangement leads to the same height of the run for all the poisons, that increases efficiency by obtaining a stable lighting installation location of the munition within a certain time. In addition to efficiency, the same height start lighting charges can improve fire safety at operation of the munition by eliminating the fall of the burning light of the charges on the ground. It should also be noted that this arrangement of charges leads to a significant increase in the reliability of the ammunition at the expense of the autonomy of the work of each of the lighting charges, when not activating any of them does not cause failure in the operation of other. Execution in the whole body of the munition holes for placement of charges allows you to split lighting charges from each other, providing each individual channel for hunting, which leads to increased reliability of ammunition in General.
Execution host serial trigger explosive charges in the base, one side of which is made annular groove with branches, which number corresponds to the number of lighting charges, allows you to split the involvement of the charges, which leads to the autonomy of the work of each of the charges and increases the reliability of ammunition. Execution host serial trigger in the form of a Foundation based on separate treatment of the t process equipment and his corps of ammunition, that increases the security of manufacturing and allows you to upgrade the host serial trigger to increase the effectiveness of the munition. Annular groove allows the above-described layout of ammunition and to achieve uniformity of operation of lighting charges, which increases the efficiency.
The junction of the base to the casing by placing explosive charges on the side opposite to the annular groove, helps to protect the expelling charges against premature actuation during the passage of the firing pulse on the ring groove and to protect them from the products of combustion, which increases the reliability and efficiency of ammunition.
Running through holes in the end sections of the branches of the coaxial holes of the housing for mounting lighting and expelling charges allows the shortest path to reliably transmit a firing pulse to each expelling charge separately, which increases the efficiency of ammunition in General.
Implementation of sections of the branches, except for the section that transmits a firing pulse explosive charge fired in the first place, adjacent to the annular groove, larger than the ends, improves the conditions of combustion of the pyrotechnic composition, placed in the crossing areas of the annular grooves in the branch is and the expense of direct contact of the compositions of the ring groove and spur, that increases the reliability and efficiency of ammunition.
Filling the annular groove retarding pyrotechnic composition allows a certain uniformity in the operation of lifting charges, and supply spur gear charges gives the ability to reliably transmit a firing pulse from retarding composition of the ring track to explosive charges, which leads to the effective work of ammunition.
Accommodation retarding pyrotechnic composition in phase firing circuit connecting eject the charge of the detonator and explosive charge fired in the first place, eliminates the possibility of interference from otstrelivayuschihsya up the body of the fuse after it has been enabled, by providing a delay between the actuation of an ejector charge fuse and the first lighting of the charge that significantly increases the efficiency of ammunition.
Execution of transfer charges, in addition to the charge transmitting a firing pulse to lifting charge fired in the first place, of a height less than the height of retarding composition of the ring groove, improves the conditions of combustion of the transfer charge, which increases the reliability of the transmission of the firing pulse from retarding composition of the ring groove to expelling charge, which again increases the eff is aktivnosti work of ammunition.

An example of carrying out the inventive device can serve as a signal flare munition for signal and lighting mines. Munition contains a steel case, which has six through-holes arranged uniformly on the outer diameter around the Central through hole. In the Central hole is eject the battery fuse and the rest a.m lifting and lighting charges. Lighting charge is a sleeve with a pyrotechnic lighting composition on the basis of nitrate of barium and aluminum. Lifting charge is a sleeve filled with gunpowder. Each hole represents a channel from which the expelling charge is torn charge of lighting at the height ˜ 50 m To the chassis founded the e, which is made annular groove with six branches. Lots of branches adjacent to the annular groove, in addition to the plot, transmitting a firing pulse to the explosive charge fired in the first place, made the same width as the annular groove, and the ends of the branches are made of a width less than 1 mm On end parts of the branches are made of through-holes aligned with the holes of the housing for mounting the lifting and lighting charges.
Annular groove is completely filled with pyrotechnic retarding composition, the burning rate which is selected so that the difference between shooting lighting charges was equal to the burning time of lighting charge (approximately 5 s).
Lots of branches adjacent to the annular groove, provided with a gear charges, made of igniter pyrotechnic composition. Transmission charges made smaller height (1 mm)than the height of retarding composition in the annular groove, in addition to the charge transmitting a firing pulse explosive charge fired in the first place.
The firing circuit connecting eject the charge of the detonator and explosive charge fired in the first place, contains a plot with the same retarding pyrotechnic composition, as in the annular groove./p>
The inventive device operates as follows.
By deploying the mines triggered eject the battery fuse 6, burn retarding composition 5, which is included in the firing circuit connecting the fuse 6 and the lifting charge 3, triggered first, and the one - retarding composition of the annular groove 7 of the base 4. As combustion retarding composition of the ring groove 7 is transferred to the firing pulse in the remaining five branches 8 of the annular grooves 7, tripping installed transmission charges 9. When triggered, the charge gear 9 through the through holes of the end sections of the branches 10 a firing pulse is transmitted to the lifting charges 3, after the ejection charge light 2 from the housing 1. Once fired off the first charge of the lighting, retarding composition of the annular grooves 7 continues to burn and with an interval of 5 seconds is consistent with the ejection of the remaining five charges of lighting 2. The lighting time of each charge lighting ≈7, i.e. there is a constant glow. Sound effect accompanied by the ejection of the fuse 6 and each of the shooting charges lighting 2. The height of departure charges lighting 2 is about 50 m Thus, the illumination area for >30 seconds is nd. To ensure fire safety charge light 2 is designed in such a way that the combustion occurs only in flight.
The efficiency of the proposed ammunition is sound and light alarm indicating the occurrence of the probable enemy and uniform coverage of the area in light and in the dark for at least 30 s, and the required reliability of the operation of the munition, obtained previously by calculation, was confirmed by the test results. It should also be noted that the inventive ammunition compared to the prototype has a small overall dimensions, which greatly increases the ease of operation and use.
