Description

The invention relates to military equipment and can be used in the construction of grenade launcher systems, mainly in reusable manual ones.

The known design of the disposable grenade launcher described in the patent of the Russian Federation No. 2169332, class. F41F 3/045, from 13.09.2000, [1], which is an analogue of the proposed device. This grenade launcher contains a launch tube with a rocket propelled grenade placed in it, a trigger mechanism, an aiming device and a belt for carrying it in the stowed position.

The advantages of the described grenade launcher design are:

- ease of operation, provided by the lack of preparatory operations for loading before firing.

Moreover, this grenade launcher also has several significant disadvantages:

- insufficient firing accuracy due to the inability for economic reasons to equip each disposable grenade launcher with a modern optical sight that measures the distance to the target, night vision, introduces corrections for the speed of movement of the target, wind, temperature characteristics, etc .;

- the impossibility of destroying multifaceted targets (tank, firing points, manpower of the enemy, buildings, etc.) due to the lack of multi-functional warheads in the form of cumulative, thermobaric, high-explosive, fragmentation, etc. in a disposable grenade launcher.

To some extent, the noted shortcomings are eliminated in the design of the well-known hand grenade launcher complex described in UK patent No. 1288732, class. F41F 3/045 [2], which is the prototype of the present invention.

The device in question contains a fiberglass pipe connected to each other by hooks and equipped with a trigger mechanism equipped with a pulsed electric generator, a docking unit, an aiming device, a carrying strap in the stowed position, and a container with a rocket-propelled grenade placed in it, an electric contact device connecting the electric generator with the ignition chains of a grenade.

The disadvantage of the described design of the manual grenade launcher complex is the insufficient degree of protection against the operation of the grenade jet engine from a pulsed electric generator with a loose connection between the launch tube and the container with the grenade.

This is explained by the fact that the pulsed electric generator, due to its high sensitivity to various shock actions under conditions of docking or undocking the pipe with the container, can give an electric impulse sufficient to trigger the ignition chains of the grenade. And this, in turn, can lead to an unauthorized shot when the launch tube is not completely closed to the container.

The technical problem to which the invention is directed is to increase the operational safety of a hand grenade launcher system, which excludes the firing of a shot when the launch tube and the container with the grenade are not completely closed.

This goal is achieved by the fact that the design of the proposed grenade launcher complex, which includes a fiberglass launch tube interconnected by hooks with a trigger mechanism mounted on it, equipped with a pulsed electric generator, docking unit, sighting device, belt, and a container with a rocket propelled grenade , an electrical contact device that connects the generator with the ignition chains of the grenade, provides the following design differences:

- the docking unit is equipped with a hook in the form of a figured two-arm lever spring-loaded relative to its axis, one shoulder of which interacts with the tooth with the annular groove of the container, and the second shoulder with a disconnector made in the form of an engine in which the roller is mounted on the longitudinal axis of the hook, interacting with the flat-conical surface of the second shoulder of the hook with providing undocking when moving the engine and turning the hook around its axis, and on the other side of the engine is fixed ennaya rod with slider in the forward position providing the closed position, the end of the link is provided with a spring-loaded conical insulator opposite the closed contacts, installed in electric-wire break device, providing them with a conical insulator opening in the rear position of the engine.

The proposed design of a manual grenade launcher system is illustrated by drawings, in which Fig. 1 shows a general view of a manual grenade launcher system, Fig. 2 shows a docking unit with a disconnector in the firing position when the launch tube is closed to the container, Fig. 3 shows a docking unit with a disconnector when not completely closed connection of the launch tube to the container.

The manual grenade launcher system contains a fiberglass launch tube 1 with a trigger mechanism 2 installed on it, equipped with a pulsed electric generator 3, a docking unit 4, an aiming device 5, a belt 6. A container 7 with a rocket-propelled grenade 8 is attached to the launch tube 1. the device 9, connecting the pulsed generator with the ignition circuit of the grenade 8, is made in the form of electrical conductors. The docking unit is equipped with a hook 10 in the form of a figured two-arm lever spring-loaded relative to its axis 11, one shoulder 12 of which is locked with its tooth 13 with a spring 14 in the annular groove 15 of the container, and the second shoulder 16 is in contact with a disconnector made in the form placed on the base 17 along the longitudinal axis the engagement of the engine 18 in which the roller 19 is mounted. This roller rolls along the conical surface 20 of the second shoulder of the engagement. On the other hand of the engine, a rod 21 is fixed with a spring 22, which provides the engine 18 is pushed to the forward position towards the hook 10, thereby creating a guaranteed tooth preload 13 in the annular groove 15 of the container, i.e. providing a closed junction of the launch tube with the container. The end of the rod 21 is equipped with a conical insulator 23, opposite which spring-loaded closed contacts 25 are mounted on the launch tube in the housing 24, installed in the gap of the conductors of the electrical contact device 9 with the possibility of their opening by the conical insulator 23 when moving the engine back. Rod 21 is also provided with a protector 26 with a protrusion.

The operation of the nodes and mechanisms of the manual grenade launcher complex, taking into account the above description, is as follows.

Before the shot is fired, the complex is put into combat position. For this, the launch tube 1 is connected to the container 7, where the rocket-propelled grenade 8 is placed, which is necessary for hitting a certain type of target, i.e. cumulative, thermobaric and other types of action.

The container with its front part is inserted into the internal cavity of the launch tube 6. For this, the engine 18 is shifted to the rear position, the rod 21 connected to it compresses the spring 22, and the end of the rod with its conical insulator 23 opens the spring-loaded closed contacts 25 located in the housing 24 on the launch tube . Thus, the conductors of the electrical contact device 9 are connected, connecting the electric generator 3 with the ignition chains of the grenade 8. When the front part of the container is fully retracted into the inner cavity of the pipe, the engine moves toward the hook 10 by the action of the spring 22, the roller 19 first rolls over the conical surface 20 of the second hook shoulder and then fixed on its flat surface, thereby ensuring the entry of the tooth 13 into the annular groove 15 of the container and fixing it in this position. This fixation, taking into account the protrusion of the fuse 26, provides a rigid blocking of the hook from turning and spontaneous exit of its tooth from the annular groove during any manipulations with the grenade launcher system. In this case, the conical insulator 23 is shifted, providing the closure of the contacts 25 when the docking unit is completely closed. After that, the manual grenade launcher system is ready to produce a shot.

If it is necessary to discharge (recharge) the undocking process described above occurs in the reverse order.

Tests and a tactical and economic analysis of a sample of the proposed manual grenade launcher complex under normal and difficult operating conditions revealed an increase in operational safety compared to the prototype, with the exception of an unauthorized shot being fired when the launch tube and the container with the grenade are not completely closed.
