Description

The invention relates to the field of weapons and can be used in the development of portable non-return grenade launchers of one-time use and takes into account the increasing requirements for the perfection of their designs.

Known manual grenade launcher [1], consisting of a launch tube, in the back of which, with the help of hooks, a container is mounted with a rocket placed in it, including a warhead with a conventional cumulative or fire charge, a rocket engine with a solid fuel charge, a nozzle and a stabilizer made, for example, in the form of a cylindrical part of the housing of the rocket engine. In this case, the solid fuel jet engine is placed in a container rigidly fastened to the launch tube.

The disadvantages of the design of a hand grenade launcher is that after starting the grenade and undocking the fired launch container, the operator (grenade launcher) has to carry a reusable launch tube, which is 6-8 kg.

Known manual grenade launcher [2], containing a launch tube-container with a firing mechanism in the handle, a grenade with a jet engine and a counter mass, while the launch tube-container is coaxially displaceable with the ability to move a counter-mass in the form of a thin-walled barrel attached to the engine, with a grenade installed in the barrel and pulled all the way to the engine by the tensioner installed in the free volume of the rear of the grenade in the form of a rod of variable diameter, the larger diameter of which with an annular throttle clearance Installed in a cylindrical perforated glass of the front bottom of the engine, turning into a prechamber, while the bottom of the glass is made with throttle holes and pulled to the grenade tensioner with a calibrated bursting element.

The disadvantage of this design is that after the launch of the grenade, the grenade launcher cannot be restored and is thrown out entirely with the handle and guidance system, which is irrational.

Therefore, the objective of the invention is to eliminate the above disadvantages, namely: ensuring the multiple use of a grenade launcher with a low-weight firing mechanism with the latest guidance and quick detaching from a fired launch tube-container, as well as eliminating the unauthorized launch of a grenade.

This task is achieved by the fact that in a hand grenade launcher containing a launch tube-container with a grenade, a firing mechanism installed inside the launch handle, a docking device, a sight, a launch handle is made in the form of a lodgement for the launch tube-container, the docking device is made in the form of front and rear hooks on the launch handle and their reciprocal hooks on the launch tube-container, and the rear hook of the launch grip is spring-loaded on the same axis as the release lever of the launch tube-container, with the relay mechanism is a small-sized pulse generator, electrically connected to the launch tube-container and combined with the trigger mechanism with a fuse, while a laser pointer with a power lever is installed inside the front of the launch handle at an angle to the longitudinal axis of the launch tube-container, and the sight is hinged , spring-loaded and cantilever mounted on the outer surface of the trigger handle.

The essence of the invention lies in the fact that this grenade launcher design allows the use of the latest guidance tools, the use of which ensures accurate and reliable target hitting at any time of the day by adjusting the sight with a laser target designator and quickly replacing the fired launch tube-container with a combat one, and also eliminates unauthorized launch of the grenade in the stowed position, since the pipe container with the grenade and the handle are separate.

In the drawings (figure 1, 2) shows the proposed design of a hand grenade launcher, where:

1 - launch tube-container with a grenade

2 - trigger handle with a firing mechanism

3 - front hook trigger

4 - rear hook of the launch tube-container

5 - electric contact group - “plug” of the starting handle

6 - electrical contact group - "socket" of the launch tube-container

7 - optical sight

8 - laser target designator

9 - trigger mechanism with fuse

10 - small-sized pulse generator

11 - the undocking lever of the used container

12 - front hook of the launch tube-container

13 - spring-loaded rear hook trigger trigger.

The operation of a hand grenade launcher is as follows: the operator (shooter) selects the target from the reach condition, removes the launch handle 2 from the special pouch located on his belt and attaches it to the launch tube-container 1, inside which the grenade is located. In this case, the front hook 3 of the launch handle 2 enters the mating front hook 12 of the launch tube-container 1, and the rear hook 4 of the launch tube-container enters, snapping into the spring-loaded response hook 13 of the handle, while the electrical contact group is ″ plug ″ 5 installed in the start handle 2 is docked with the contact electrical group - "socket" 6, mounted on the launch tube-container. The operator, holding the trigger handle with the trigger, installs a grenade launcher on his shoulder, flips out a spring-loaded console mounted optical sight 7, which is fixed by a spring at a distance convenient for the operator’s eye, and takes aim - this is during the daytime. When working at night, the operator, moving the lever, turns on the laser pointer 8, which illuminates the target with a very bright small dot visible in the optical sight, which is aligned with the laser pointer, and, taking off the fuse, launches the grenade at the target by pressing the trigger mechanism 9, combined with a small pulse generator (MIG) 10 installed in the handle. At the same time, the necessary electric impulse appears in the MIG to start the grenade engine, after which the grenade flies out of the launch tube-container and hits the target. To replace a fired launch container with a combat operator, by pressing a finger on the spring-loaded detachment lever 11, which is on the same axis as the rear hook of the firing handle, detaches the firing pipe-container, then the operator abruptly drops the focus of the fired launch container against the shoulder and dumps it.

The laser designator is installed inside the front of the launch handle at an angle to the longitudinal axis of the launch tube-container. The angle is calculated taking into account the ballistic trajectory of the grenade, launched at a range provided by laser illumination, is constant and is laid in the design of the launch handle.

A small-sized pulse generator is designed to convert mechanical energy into electrical energy, made in the form of an induction coil, inside which a permanent magnet is installed, combined with a trigger mechanism. When you pull the trigger, the permanent magnet, moving, crosses the magnetic field lines of the coil, as a result of which the necessary electrical impulse appears in the coil, which is supplied to the grenade’s electric igniter via an electric circuit through the combined contact group ″ plug-socket ″.
