RU2655706C1 - Launcher grenade for hitting enemies behind an obstacle - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to hand grenade launchers. To hit the hiding enemy the grenade launcher has tail unit significantly protruding across the flight for the envelope of the warhead of the grenade. Tail unit is made folding and in the folded state the edges it forms parallel straight lines. Grenade flies by, say, a corner of the building, clings to the corner by the tail unit, and from this jerk the fuse triggers. Warhead of the grenade at this time is located about 60 cm behind the obstacle, explodes and strikes an enemy with fragments and a blast wave from the side (or from above, if he is in a trench).

EFFECT: grenade launcher is designed to hit the hiding enemy.

Description

The invention relates to grenades for hand grenade launchers.

Known for such grenades, over-caliber and caliber, see, for example, US Pat. No. 2499973 and 2513629, Internet. The invention relates to both types.

A disadvantage of known grenade launchers is the impossibility of hitting an enemy who has taken refuge behind the corner of a building, beyond the edge of a window or doorway, behind a tree or pillar, or behind a trench parapet.

The objective and technical result of the invention is the elimination of this drawback.

For this, the grenade has a plumage that protrudes significantly across the flight beyond the envelope of the warhead of the grenade, that is, in the radial direction - at least three times (see Fig. 1). Really - 10 times or more.

Of course, the plumage is more convenient to make folding, and when folded, the edges of the feathers of feathers form parallel lines, and the feathers have a rectangular or trapezoidal shape. This is a prerequisite for placing a grenade in the tube of a caliber grenade launcher.

If the maximum transverse size of the folded plumage is also equal to the diameter of the warhead of a grenade, then such a grenade will fit well in the barrel of a caliber grenade launcher. That is, in other words, when folding the plumage, the edges of its feathers form the edges of a regular multifaceted prism, and the "radius" of this prism is equal to the radius of the warhead of the grenade. In this folded state, a grenade with plumage with the necessary clearance enters the barrel of the grenade launcher and is well fixed in it (that is, it does not hang). Caliber grenade launcher will fire more accurately.

The optimal number of feathers is 4-5. And only if necessary, reduce the length of the equipped grenade can you use 6 feathers. Feathers should be rigid, that is, it is desirable to make them from carbon fiber.

The outer end of the pen grenade should cling well to any surface, so it either just needs to be in the form of an acute angle, or it should have a bevel in which a sharp needle should be fixed, oriented so that in the open state of the tail it is oriented forward or forward-outward . That is, it is a hook that should cling to everything. However, ideally smooth surfaces are almost never encountered in battle, so it’s enough to just have a sharp, not rounded bevel angle.

If the grenade starts to rotate during a shot, then no special devices are needed to open the plumage - the feathers will open under the action of centrifugal force. In the absence of rotation, the grenade feathers should be slightly spring-loaded in the direction of opening.

No special stop for open feathers is also required; they will abut with their rear ends into the tube of the rocket engine. In the place of this contact feathers should be reinforced (increased thickness).

The grenade may have a full-time fuse, or - better, a high-sensitivity fuse (verified experimentally). Such fuses are known.

It is not recommended to give the feathers an angle of attack (more precisely, an aerodynamic step), as this will reduce the longitudinal stiffness of the pen.

In FIG. 1, 2 shows this grenade. It consists of a warhead 1, a rocket engine 2, eight pillars 3, in which four feathers 4 are articulated. The feathers at the front ends may have needles 5 (the outer end of the upper feather is shown in FIG. 2). It is assumed that the grenade is calibrated, that is, the feathers 4 in the folded state lie on the body of the rocket engine 2, and in this position the resulting transverse "cross" has a size equal to the diameter of the warhead 1. In this form, the grenade is charged into the barrel of the grenade launcher.

A grenade works like this: let's say the enemy fires from behind the corner of a building or rock, from a door or window of a building, from armored vehicles, from a tree in a forest, from a parapet parapet, from a steel shield, etc. P. When fired at him, the soldier aims so that the grenade flies next to the obstacle behind which the enemy took refuge, at a distance less than the length of the grenade's feather. Either below or above this obstacle. That is, if the maximum swing of the grenade feathers in the open state is 1.1 meters, the soldier aims so that the grenade flies 20-30 cm from the obstacle (horizontally or vertically, according to the type of obstacle).

A grenade flies nearby, for example, with the corner of the building, clings with a pen or a needle to the pen around the corner, and a fuse is triggered by this jerk. The warhead of the grenade at this time is approximately 60 cm behind the obstacle, explodes and hits with shrapnel and a blast wave from the side (or below, if it is in the trench) of the enemy.

If the adversary is in the window or door of a building with thick walls, or behind a thick ledge of rock, then the mentioned 60 cm may not be enough. In this case, the fuse should fire with a delay, ensuring the passage of the grenade another meter. The delay can be adjustable depending on the obstacle. Or for the same purpose, you can increase the length of the rocket engine, for example, up to 1 meter. It is possible to increase the mentioned length a little more, if in the open position to give the feathers a moderate sweep - no more than 10-20 degrees (otherwise their radius decreases, that is, the distance from the axis of the grenade to the end of the feather).

In the place where the folded feathers lie on the rocket engine housing, it is desirable to have two protrusions on each rocket on the rocket engine so that the folded feather lies absolutely parallel to the longitudinal axis of the grenade.

Of course, a good scope is desirable, preferably with a zoom and rangefinder.

To increase the accuracy of the shot, the grenade launcher should have a rotating barrel (this is a separate, simultaneously filed invention).
