 Fuse for hand grenades / 2255301
Fuse for hand grenades has a bush of the detonation assembly connected inside the grenade body that is connected to the cavity of the fuse outer body, positioned in which is an additional functional assembly of the time fuse, that has a pyrotechnical retarder and a flash igniter, which is positioned in the side seat of the fuse body for initiation of the given flash igniter by means of a trigger pricking-safety mechanism that is positioned in the seat of the fuse body asymmetrically relative to the longitudinal axis of the bush of the detonation assembly of the given fuse. The novelty is in the fact that there is a time controller of the hand grenade blast, which contains a shaped retarder frame rotating in the longitudinal axis of the detonation assembly bush. The frame is made for transmission of the initiating fire impulse from the side flash igniter to some section of the side outer surface of the rotating horizontal semi-ring component that has the respective profile for arrangement of the pyrotechnical component of the retarder on it, and connected to the radial component that is positioned in the radius of the horizontal semi-ring component for further transmission of the initiating fire impulse to the time assembly of the fuse, which initiates the main charge of the hand grenade. Provision is also made for a setting and fixing mechanism of the retarder shaped frame through a preset angle of its turn for determining the angle of setting of the rotating shaped frame of the retarder relative to the side flash igniter according to the digital graduated scale of the time fuse, having an increased time range.

FIELD: weaponry. SUBSTANCE: invention relates to training hardware allowing simulation of actual combat means. The fuse for training hand grenade includes the case with the blasting fitted therein, pyrotechnic retarder and safety-piercing mechanism consisting of a ring with cotter-pin, spring-loaded firing pin and the lever. Inside the casing, the plug is coaxially arranged with blunt bottom accommodating a smoke, sound and/or light charge and weakened plug and with a through aperture in a lateral wall on which a pyrotechnic retarder is fitted. EFFECT: prevention of fuse destruction after burning of pyrotechnic retarder and opportunity of multiple use of hand grenade case. 2 cl, 2 dwg
The invention relates to the technical training device that provides simulation of real combat action tools, particularly to fuses for manual training grenades. Known fuse for hand grenade non-lethal actions (RF patent No. 2235289). The fuse includes a housing with located therein primer-igniter pyrotechnic delay fuse, primer-detonator and detachable for security, safety nekolny mechanism. The body of the igniter is made of soft plastic, not forming dangerous splinters. The disadvantage of this technical solution is remaining in the heat of the blasting cap is triggered, for example, after combustion of the retarder, which can lead to accidents in the operation of the igniter. In existing garnets special charges (smoke, sound and/or light) are placed in the housing of the valve, and the fuse only initiates the specified charge. The problem solved by the claimed invention is to develop such a fuse, which would ensure his safety, and to increase the effectiveness of grenades. The technical result consists in preventing the destruction of the body of the igniter after the combustion of the pyrotechnic moderator, opportunities reusable housing grenades and strengthening of smoke, zvukovoj and/or light signal. The technical result is achieved in that the fuse for training hand grenades includes the case where the primer-igniter pyrotechnic delay fuse and bursting-nekolny mechanism, consisting of a ring with a cotter pin and a spring-loaded pin, is held by the lever. Inside the housing is installed coaxially to the housing sleeve, which has a blind bottom and closes the weakened door. In the sleeve posted by smoke, sound and/or light charge, and in the side wall of the sleeve is a through hole, which establishes the pyrotechnic moderator. In the proposed variant smoke, sound and/or light charge is placed in the heat of the moment, and not in a pomegranate. This solution allows you to store pomegranates as products with no hazardous substances, which in turn increases the safety of operation grenades and provides multiple chassis grenades. Due to the coaxial installation of the bushing in the housing of the igniter ensures the integrity of the body of the igniter, as accidental breakthrough of gases through the wall of the sleeve they will expand inside the body of the fuse, and will not lead to the destruction of his body. Placement of smoke, sound and/or light charge in the installed coaxial to the casing of the fuse sleeve with a hollow bottom and weakened plug avishay safe operation grenades due to emission caps in a given direction and provides multiple chassis grenades by reducing loads in other directions. This design provides a directional exit from the combustion of the charge gases through the body cavity training grenades, which leads to improvement of the technical characteristics of grenades with a less weight of the charge. Fixing pyrotechnic moderator in a through hole of the side wall of the sleeve allows the momentum transfer (by ensuring the necessary time deceleration) from primer-igniter to the Central part of the charge. The momentum transfer in the Central part of the charge provides for the distribution of the combustion front in a weakened side stub, and in the direction of the back bottom of the sleeve that ensures the timely triggering of charge to release weakened stub - this improves the utilization ratio of the mass of the charge, which leads to the increased smoke, sound and/or light signal. Pyrotechnic retarder may be connected to the housing of the igniter, which further can improve the reliability of the igniter (due to increased strength and reliability (prevents the departure of the sleeve from the ignition of accidental loosening of the sleeve). The figure 1 shows the design of the igniter in the longitudinal section. Figure 2 - connection of pyrotechnic moderator with the body of the igniter. The fuse consists of a body 1 located in it will protect the flax-nekolny mechanism, consisting of ring 2 with pin 3, of a spring-loaded striker 4 and the lever 5, as well as posted primer-igniter 6, pyrotechnic retarder 7, mounted in a through hole of the side wall of the sleeve 8 with smoke, sound and/or light charge 9, closed weakened by the cap 10. In the service position, the arm 5 holds the striker 4, and the fixed locking pin 3 ring 2. Before application of the established in the training grenade fuse when pressed against the body of the grenade lever 5 for ring 2 pull out the cotter pin 3. When throwing grenades lever 5 releases the spring-loaded striker 4, which pins primer-igniter 6, resulting gases fire pyrotechnic retarder 7, after burnout moderator lit a smoke, sound and/or light charge 9. Formed during combustion of the charge gases emit weakened the cover 10 and, leaving the shell of the grenade, create smoke, sound and/or light signal, simulating the firing of a real grenade. The advantage claimed igniter is high security, reliability simulate the actions of a real grenade and reusability hand grenades in the learning process. 1. The fuse for the training hand grenade comprising a body with located therein primer-igniter pyrotechnic down elem and safety nekolny mechanism, consisting of a ring with a cotter pin, a spring-loaded striker and lever, characterized in that it contains installed coaxially inside the sleeve with a hollow bottom placed in her smoke, sound and/or light charge and loosened the cap and with a through hole in the side wall, which establishes the pyrotechnic moderator. 2. The fuse according to claim 1, characterized in that the pyrotechnic retarder connected to the housing.
