Abstract

FIELD: military equipment, in particular, stationary and movable automatic small arms mounts. SUBSTANCE: the rocket launcher has a cradle with a spring-loaded slide, elevating mechanism and a magazine with an ammunition stowage. The elevating mechanism is made in the form of an electric drive with an extensible rod that coupled to the cradle by means of a shackle and transverse support. The rocket launcher ammunition stowage is positioned in an armored magazine fixed on the turret. The rockets in the magazine are installed vertically, interconnected with the aid of links forming a belt that is brought to the rocket launcher through a guide neck with rollers and a tube fixed in the axis of rotation of the rocket launcher. EFFECT: reduced time of weapon elevation, eliminated probability of hitting of the shooter and ammunition by bullets and fragments, as well as improved conditions of packing of the ammunition stowage in the magazine. 2 dwg

Description

 The invention relates to military equipment, and more particularly to stationary or mobile installations of small automatic weapons. The invention can be applied in armored vehicles for additional armament of tanks, infantry fighting vehicles and armored personnel carriers, as well as in stationary rifle-gun remote control installations.

 It is known to install the PKT course machine gun on the T-54M tank [1], which is located inside the tank, to the right of the driver’s seat. The installation consists of the following main parts: an arm with front and rear sliders, in which a machine gun is mounted, a magazine-box, a drive (for cocking moving parts of a machine gun) and a machine gun loophole seal. A firing machine gun is a driver. The disadvantage of the installation is the lack of an independent sector of machine gun shelling, since its guidance in the target is carried out by turning the tank.

 Known installation of a machine gun PKT, coaxial with a gun on the T-54M tank [2]. The installation is mounted inside the tank tower on the cradle of the gun. Aiming the machine gun at the target is through a telescopic sight using stabilized or manual drives. The machine gun installation consists of the following components: bracket, rear support, frame, trap, front and rear struts, front and rear sliders, shock absorber and frame seal with guide cover for installing a magazine box with cartridge belt. The disadvantage of the installation is the long time the machine gun was aimed at the target due to the large moment of inertia of the moving parts of the installation, including the artillery gun.

 The known armament complex of the armored object [8], which, according to the authors, is the closest technical solution to the claimed object and is selected as a prototype.

 The armament complex of an armored object consists of a main gun mounted in an armored turret with the possibility of pointing it in a vertical plane, and a grenade launcher placed on a turret of a combat vehicle.

 The grenade launcher is mounted on a carriage equipped with a flange, by means of which it is fixed on the roof platform of the armored turret with the possibility of adjustable rotation about the vertical axis.

 The disadvantage of the grenade launcher is the large time for vertical guidance on the target, carried out together with the main weapon.

 The objective of the invention is to reduce the time of vertical guidance of the weapon, as well as eliminating the possibility of damage to the ammunition by bullets and fragments and improving the conditions for laying the ammunition of the grenade launcher in the store.

 The problem is solved in that in a grenade launcher placed on the tower of a combat vehicle and containing a cradle with a spring-loaded slider, a lifting mechanism and an ammunition magazine, the lifting mechanism is made in the form of an electric drive with a retractable bayonet connected by means of an earring and a transverse support to the cradle. The store is made armored. The ammunition grenades in the store are installed vertically and connected to each other by links forming a tape connected to the grenade launcher through a guiding neck with rollers and a pipe fixed along the axis of rotation of the grenade launcher.

 The implementation of the lifting mechanism in the form of an electric drive with a retractable rod connected by an earring and a transverse support with a cradle, reduces the time of vertical aiming of the weapon at the target. Placing a grenade launcher ammunition in an armored store mounted on a turret eliminates the possibility of damage to grenades by bullets and splinters, and in case of ammunition detonation it eliminates the defeat of a tank crew or infantry fighting vehicle. Installing grenades in the store vertically, supplying the tape to the grenade launcher through the guide neck with rollers and a pipe fixed along the axis of rotation of the grenade launcher improves the conditions for placing the ammunition in the store and supplying the guarantor to the weapon.

 The invention is illustrated in graphic materials, in which Fig. 1 shows a general view of a grenade launcher, a side view, and Fig. 2 is a top view of a grenade launcher.

 The grenade launcher consists of a cradle 1 pivotally mounted on a fixed bracket 2. In the cradle there is a spring-loaded slider 3 in which a grenade launcher is mounted 4. An electric actuator 5 with a retractable rod 6, on which the earring 7. is pivotally mounted, is mounted on the fixed bracket 2. is bolted to the transverse support 8, pivotally mounted on the cradle 1. In the armored store 9, the ammunition load of the grenade launcher 4. The ammunition load of the grenade launcher consists of vertically mounted grenades 10, is connected links with each other 11. Grenades 10 through the guide neck 12 with the rollers 13 and the pipe 14 are led to the grenade launcher 4. The axis of the pipe 14 coincides with the axis of rotation of the grenade launcher 4. On top of the armored magazine 9 is closed by a cover 16. The cradle 1 using the rod 17 and the lever 18 is connected to a position sensor 19, mounted on a fixed bracket 2.

 Grenade launcher works as follows. When the handles of the gunner’s control panel are rejected, the sighting line of the gunner’s sight is aimed at the target. The resulting mismatch angles between the sighting line of the gunner’s sight and the grenade launcher are received in the form of electric signals from the sensors of the angular position of the mirror of the gunner’s sight and from the position sensor 19 of the grenade launcher 4 (VN channel) and the gyroscopic angle sensor (VN channel) to the stabilizer control unit and through amplifiers power to the electric motors of the lifting and swiveling mechanisms that rotate the grenade launcher and the tower in the direction of decreasing the mismatch angles, i.e. the barrel of the grenade launcher tracks the stabilized sight line of sight of the gunner’s sight, keeping the position of the barrel of the grenade launcher relative to the line of sight of the gunner’s sight unchanged. Shooting is carried out by pressing the shooting button on the handle of the gunner's control panel. The length of the queue depends on how long the button is pressed. Grenades 10 through the guide neck 12 with the rollers 13 and the pipe 14 enter the grenade launcher 4. The axis of the grenades change their direction, which is determined by the rollers 13 and the receiving window of the grenade launcher 4. The empty link is thrown out through the trunnion 15. When placing the ammunition in the armored store 9, the lid 16 is separated and the grenades 10 connected by links 11 are vertically mounted in the magazine section and through the guide neck 12 and the pipe 14 are inserted into the receiving window of the grenade launcher 4. The grenade launcher is charged and the armored magazine 9 is closed by the lid 16.

 Thus, the proposed technical solution allowed to reduce the time of vertical guidance of the grenade launcher, to eliminate the possibility of hitting the shooter and ammunition with bullets and fragments, and also to improve the conditions for laying the ammunition of the grenade launcher in the store.
