Description

The proposed utility model relates to the field of weapons technology and can be used as practical training property (ISP) for grenade launchers for training personnel in the rules and techniques of firing from grenade launchers in real conditions.

A practical weapon system for an anti-tank grenade launcher is described in US Pat. No. 6,145,440, which is a practical launcher that simulates a hand-held anti-tank grenade launcher equipped with a rifled barrel from which small-caliber training munitions or bullets are fired. The rifled barrel is connected to the camera to accommodate sub-caliber ammunition. A rifled part is provided in the barrel to stabilize the practical ammunition in flight by rotation. This increases the firing accuracy of a practical launcher.

The described device cannot be used to simulate firing shots with a jet engine and plumage. This is due to the fact that it is practically impossible to combine the ballistic trajectory of ammunition fired from a rifled barrel with the trajectory of a grenade stabilized by plumage over the entire range of firing range. In addition, the use of ammunition stabilized in flight by the plumage allows you to take into account the lateral wind corrections that are typical for firing feathered combat grenades, which is necessary when learning to shoot from a grenade launcher.

Known practical weapon system for anti-tank grenade launcher described in international application WO No. 95/18948

(prototype) and which is a training manual grenade launcher with a coaxially calibrated barrel and a small-caliber training shot. In the breech of the training grenade launcher, a marking charge is fixed. The marking charge is ignited by the powder gases of a small-caliber shot and during combustion creates a force of flame and sound pressure from the breech of the training grenade launcher. Thus, the trainee (grenade launcher) is exposed to noise and sound pressure during firing. The breech of the training grenade launcher contains a node in which there is a threaded hole for attaching a small-caliber barrel, a hole for attaching a marking charge, and also contains nodes of the percussion mechanism and strikers for engaging the capsule of the training cartridge with a tracer bullet.

The disadvantage of the practical weapon system, taken as a prototype, is the presence of a practical shot, consisting of two separately charged parts - the actual training ammunition and the marking charge.

With multiple firing from a practical weapon system, this practical shot design requires a lengthy process of loading the weapon, and at the same time, increased security measures are required.

In addition, when shooting with tracer bullets, the arrow is affected by the force from a grenade launcher of one direction (recoil), while when shooting from a manual anti-tank grenade launcher, the arrow is affected by an alternating pull-back force.

This utility model is aimed at creating a set of practical training equipment for training shooting, allowing effective training of personnel

rules and methods of firing from hand grenade launchers using small-caliber grenades with a jet engine and plumage.

The technical result consists in an almost complete imitation of the technical characteristics of a combat disposable anti-tank grenade launcher (including the flight path of a grenade), as well as the reusability, simplicity and ease of loading a training grenade launcher with a practical shot.

The technical result is achieved by the fact that a set of practical training equipment for training in shooting from a disposable anti-tank grenade launcher consists of a training hand grenade launcher with a coaxial sub-caliber barrel and a practical sub-caliber rocket-propelled grenade with an igniter capsule and an open plumage. The training manual grenade launcher contains a shutter in the form of a reclining case with a pusher located in it, driven by an eccentric with a lever, and the grenade contains a sleeve with a bracket in which a gas duct and a capsule sleeve mounted in the bolt are fixed, while a feather stabilizer and a jet are placed in the sleeve an engine, the nozzle cut of which is connected to the sleeve with a sheared element.

The shutter of a training manual grenade launcher in the form of a reclining case with a pusher located in it provides multiple reloading of a practical rocket-propelled grenade and its fastening in the grenade launcher by the capsule sleeve.

The pusher, driven by an eccentric with a lever, provides a tight, without distortion, installation of the igniter capsule in the charging chamber.

The presence in the grenade of a sleeve with a bracket in which the gas duct and capsule sleeve are fixed, and the placement of the stabilizer and jet engine feathers in the sleeve, provides the convenience and simplicity of loading the training grenade with a grenade.

The connection of a jet cut of a jet engine nozzle to a sleeve with a sheared element, for example, a screw, determines the force exiting the grenade from the liner and allows you to choose the imbalance when firing a training grenade launcher (roll-back), like a combat analogue.

The utility model is illustrated by drawings, which depict:

- figure 1 is a set of practical training property;

- figure 2 is a practical sub-caliber rocket propelled grenade;

- figure 3, 4, 5 - shutter in a closed, open and reclined position, respectively;

- Fig.6, 7, 8 - loading a grenade launcher with a practical rocket-propelled grenade.

A set of practical training equipment (Fig. 1) contains a training manual grenade launcher 1 and a practical sub-caliber rocket-propelled grenade 2. The grenade launcher has a coaxially calibrated barrel 3 and a bolt 4 for attaching a grenade.

Practical sub-caliber rocket-propelled grenade (figure 2) includes a jet engine 5 with a feather stabilizer 6, placed in the sleeve 7, the capsule sleeve 8, the gas duct 9, which are fixed in the bracket 10 of the sleeve 7. The nozzle section of the jet engine 5 is connected to the sleeve using a sheared element 11. In the capsule sleeve 8 is placed the igniter capsule 12.

The shutter (Figs. 3, 4, 5) consists of a base 13 and a housing 14. In the shutter housing 14 is a pusher 15, driven by an eccentric with a lever 16. On the side surface of the base 13

shutter latch 17 is installed.

The shutter 4 (figure 1) is attached to the training grenade launcher, for example, using rivets.

The work of a set of practical training property is as follows.

To load the training grenade launcher, you must:

- move the lever 16 (figure 3) from the front to the rear (figure 4), while the pusher 15 will move back, the pusher pins will come out of the holes B in the base 13 of the shutter;

- holding the lever 16 (figure 4), turn, counterclockwise, the shutter body 14 (figure 5, 6) around the axis 18 until it stops;

- insert into the sub-caliber barrel 3 (Fig.6) a practical rocket-propelled grenade 2 (Fig.7) so that the capsule sleeve 8 is inserted through the groove B until it stops into the base 13 of the shutter;

- grab the lever 16, turn clockwise the shutter body 14 around the axis 18. Move the lever 16 from the rear to the front position, while the latch 17 should snap into the hole A of the lever 16. The training hand grenade launcher is ready to fire (Fig. 8).

After pointing the grenade launcher at the target, by pressing the trigger lever, the trigger mechanism is triggered and the igniter 12 is pierced (FIG. 2). The igniter capsule ignites the powder mount, which ignites the grenade jet engine 5 through the gas duct 9. The powder gases of a jet engine knock the tube of the gas duct 9 from the breech of the grenade launcher, as well as the military counterpart.

Under the action of reactive force, the sheared element 11 is destroyed and the grenade moves along the internal barrel of the grenade launcher.

The powder charge of the engine burns out when the grenade moves along the barrel, and the powder gases expire from the breech of the grenade launcher, as in a military counterpart. When the grenade leaves the barrel, the feathers of the stabilizer 6 open and the grenade flies to the target.

To re-shot, move the lever 16 (Fig. 3) from the front to the rear (Fig. 4), turn the shutter body 14 around the axis 18 (Fig. 5) counterclockwise, remove the sleeve 7 (Fig. 2) with the bracket 10 and capsule sleeve 8, insert the next practical grenade 2 (Fig. 1), close the shutter in the reverse order.

The implementation of the proposed technical solution in the form of a set of practical training equipment, confirmed by real firing, allows you to almost completely simulate the technical characteristics of a disposable anti-tank grenade launcher (including the flight path of a grenade), and also provides multiple, simple, safe and convenient loading of the training grenade launcher with a practical shot.
