Description

The invention relates to ammunition for underbarrel grenade launchers, which are mounted under the barrel of AK series assault rifles. It is designed to detect and destroy enemy manpower, both openly located and hiding behind artificial and natural folds of the terrain and inaccessible to defeat.

Currently, for firing from 40-mm grenade launchers, ammunition is used, both main (with fragmentation, high-explosive, cumulative and incendiary grenades), and special-purpose (with lighting, smoke and gas grenades), the maximum flight range of which does not exceed 400 meters . With the development of reconnaissance means, the target detection range has increased, so the maximum flight range of the ammunition is not enough to defeat it.

In order to eliminate this shortcoming and improve the accuracy of hitting a target, there is a prototype (US Army) for firing from 40-mm M203 grenade launchers, 180 mm long with a cylindrical body and an ogive or flat nose fairing, capable of moving at a speed of up to 20 m / s at a distance of up to 10 km, within 12-20 minutes. A fragmentation, armor-piercing, smoke or thermobaric warhead, or a reconnaissance system with a video camera can be placed in the head of the ammunition.

Despite the high declared characteristics, the prototype is not without drawbacks, the main of which is the lack of the ability to detect and hit a target, monitor the result of hitting a target and further monitor the battlefield with a single shot. To accomplish these tasks, it is necessary to use two ammunition, one for target detection using a reconnaissance system with a video camera or observation of the battlefield, the second for inflicting damage with a fragmentation or thermobaric warhead. Another not unimportant disadvantage is the lack of the possibility of reusable use of this ammunition, since all the ammunition takes part in hitting the target.

The task to be solved by the present invention is to increase the effectiveness of an underbarrel grenade launcher by increasing the range of the ammunition and the probability of hitting a target by combining the modes of detection and hitting a target in it, while ensuring minimal overall weight characteristics and financial costs for its production.

The invention proposes a new ammunition for the grenade launcher GP-30 (GP-34), which includes several parts. In the front part there is a detachable warhead with target detection elements (video camera). In the middle of the ammunition is a housing with electronic filling and folding supports with miniature electric motors and propellers installed on them. The design is completed by a replaceable propellant charge. The ammunition is controlled by the shooter-operator using a portable device, such as a tablet.

In the complex, the proposed ammunition is able to improve the characteristics of standard ammunition for an underbarrel grenade launcher and solve the above problems.

The essence of the invention is illustrated by the drawing, which has a purely illustrative purpose and does not limit the scope of the claims. The drawing shows the proposed ammunition with a combination of modes of detection and destruction of the target to the underbarrel grenade launcher.

The invention is illustrated by the drawing, which shows:

in fig. 1 - general view of the ammunition with the mode of detection and destruction of the target to the underbarrel grenade launcher in the pre-combat state;

in fig. 2 - scheme of ammunition with the mode of detection and destruction of the target to the underbarrel grenade launcher.

An example of the invention is an ammunition for an underbarrel grenade launcher with a combination of detection and target destruction modes, adapted to the dimensions and configuration of a regular 40-mm grenade launcher ammunition, which is not the only possible one, but clearly demonstrates the implementation of the proposed design in a stable relationship of structural elements.

The proposed ammunition is a warhead 1 and a bearing part of a cylindrical shape. Four through slots 3 are provided in the wall of the body 2 of the carrier part, in which four folding supports 7 with electric motors 8 and propellers 9 are placed before launch. navigation 11, a signal transmitter 13, a video camera 15 and an electromechanical breaker of the warhead from the body of the bearing part 14. On the shank 10 of the body 2, a replaceable combustion chamber 18 with an igniter capsule 20 and filled with a powder propellant charge 19 is screwed into the thread. The rear wall of the compartment is reinforced to protect against exposure to powder gases.

The warhead of the ammunition directly includes a bursting charge of explosive 1, a fuse 16 and a built-in video camera 17. On the adjacent side of the warhead to the body of the bearing part there is a mount for the undocking mechanism.

The described ammunition functions as follows.

In FIG. 3A schematically shows the process of firing from an underbarrel grenade launcher with ammunition in the mode of detection and destruction of the target.

When fired, the primer-igniter 20 is initiated, the impulse of which ignites the powder propellant charge 19. The generated powder gases create excess pressure, by which the ammunition is fired in the direction of the enemy.

The existing propellant charge ensures the launch of ammunition at a speed of 76 m / s at a distance of up to 300 meters and a height of up to 50 meters. When it reaches the upper point of the flight path (changes in height from increasing to decreasing value, which will correspond to the maximum gained height of the ammunition and the inclination of the warhead below the rear of the hull relative to its longitudinal axis), the height sensor 6 sends a signal to unfold the supports 7 and start the engines 8 with propellers 9. The ammunition hangs in the air, the video camera 17 starts working, the operator, receiving an image from it, monitors the target and remotely controls the ammunition.

In FIG. 3B schematically shows the principle of control and further use of a grenade launcher with a mode of detection and destruction of the target. Onboard equipment provides two-way data exchange and video signal transmission to the operator. Ammunition control and target observation is carried out by the operator using a portable device, such as tablet 21 from the ground (shelter).

When a target is detected using a video camera 17 built into the body of the warhead 1 of the ammunition, depending on the chosen method of hitting it, the operator managing this ammunition can:

- to make a purposeful movement of the ammunition to the target with the subsequent detonation of the warhead 1;

- to reset the warhead 1 to the target, according to the signal given from the control module 21 to the electromechanical disconnector of the ammunition 14, and then, depending on the remaining charge of the battery - power source 4, to carry out a short-term observation using the second video camera 15 located in the body of the ammunition for the result of hitting the target and to return the bearing part to the required area for re-equipping the powder propellant charge 19 and the warhead 1 for the purpose of reuse.

For the reuse of ammunition, the change of warhead and powder propellant charge, the shooter-operator can independently perform in the field.

The tactics of using the proposed ammunition allows the simultaneous use of several such ammunition with simultaneous air strikes on targets of various classes, significantly increasing the accuracy and range of hitting the target compared to the existing ammunition for the underbarrel grenade launcher. The presence of the camera itself is an obvious advantage for troops operating in small groups, increasing the likelihood of detecting and hitting a target, both openly located and hiding behind artificial and natural terrain.
